Shimano 12-speed Dura-Ace Di2 launched the wired version in 2021 and got a small 2024 update. Is the $4,300 full-kit price worth it?
The Garmin HRM 600 is a premium ECG chest-strap HRM with rechargeable Li-ion (2 months at 1 hr/day), detachable sensor pod (machine-washable strap), step speed loss and ground contact balance, secure BLE pairing, and on-board activity recording. Matches Polar H10 within ±1 bpm. 5 ATM water rating. $169.99.
In a 5-activity study with 10 participants, the Polar H10 achieved 99.6% signal quality vs 94.6% for the Holter ECG monitor — the traditional medical reference. The H10 remained stable through high-intensity running and strength training, where the Holter signal quality dropped 8-10%. The Pro strap (anti-slip silicone + snap closure + interference-resistant electrodes) keeps the signal locked during high-sweat efforts. 400-hour CR2025 battery, 1000 Hz internal sampling, 5 kHz GymLink for gym equipment, 2 concurrent BLE + ANT+.
The Wahoo KICKR V6 delivers ±1% power accuracy, 2,200W resistance, Wi-Fi Race Mode, and pre-installed 11-speed cassette at $1,049.99. The benchmark indoor trainer, refined for 2026.
Zipp redesigned the 454 NSW — 58 mm rim depth + SawTooth wave + hookless bed. This is the most aero-efficient climbing wheel in Zipp’s history.
Trek claims the new Émonda SLR is the “lightest production climbing bike on the market” — 6.2 kg flagship with 900-series OCLV carbon.
The Garmin Fenix 7 Solar is the most all-round outdoor sports watch today — GPS accuracy, battery life, training features, maps, and solar charging are all there.
The 2024 SRAM Red eTap AXS upgrade is the strongest wireless electronic groupset today — shift speed and reliability fully improved.
1.2" AMOLED touchscreen (1500 nits), 5 physical buttons + touch, 40g, Gen 4 optical HR sensor, 13-day smartwatch / 5-day AOD battery, 60 sport modes, training readiness, training status, acute load, VO2 max trend, Garmin Share, quick workout, race widget, Garmin Pay. JoyVelo internal testing, 4 weeks.
The Zwift Ride Smart Frame is a stationary-bike frame that pairs with any Zwift-Ready trainer (KICKR Core, V6, JetBlack Victory, Zwift Hub) for virtual shifting, silent single-speed operation, and built-in handlebar controllers. 3 weeks of testing: ±2% power, 24 silent virtual gears, single Bluetooth pairing, 20h battery. $799.99 frame-only, $1299 full bundle.
The 2024 Garmin Edge 840 Solar adds solar charging to the 840's touch + button interface, 26h battery (32h with solar), multi-band GNSS, and $499 MSRP. The mid-range Edge to beat.
Favero’s Look Keo compatible Pro spindle. 130 g per pedal, 160 h battery, 28 tension steps, and a 5° cleat that snaps cleaner than the Look original. Two months of testing and we agree with the marketing line.
The PRO RS is Favero’s dual-sided road pedal — same Pro spindle as the PRO MX, but in a Shimano SPD-SL body. At 124 g per pedal it undercuts Dura-Ace 9000 and crushes Garmin Rally RS by ~200 g per set, with no compromise to Q-factor or stack height.
Cervélo redesigned the S5 — lighter, more integrated, and more aggressive aero shape. Is the $13,500 flagship aero road bike worth it?
The ENVE SES 6.7 embodies the ‘different front and rear rim depth’ design philosophy — 60 mm front / 67 mm rear. $3,800 / pair.
AMOLED 2000 nits (Suunto’s MIP era is over except for dive watches), 65h dual-band GPS (matches solar MIP watches), 20-day smartwatch, 250h Tour mode, magnetic charging (no more accidental disconnection), LED flashlight with SOS + breathing + red strobe modes, $100 price hike vs Vertical 1 ($499 -> $599). JoyVelo internal testing, 4 weeks, 70km mountain hike.
Radar + 1080p camera + tail light in a single unit. $399 launch, 147g (2x RTL 515), 4-10h battery depending on camera mode, Micro SD storage, USB-C, ANT+ radar + light + Bluetooth + Wi-Fi. The radar is best-in-class (same RTL 515 chipset). The camera is subpar: no image stabilization, 720p/1080p options, poor low-light performance, no lens protection. The Varia app UX is poor. The 16GB SD card is too small for 1080p recording. JoyVelo internal testing, 3 weeks.
MIP screen with optional Solar version, 7 physical buttons + touchscreen, 26h battery, free ClimbPro (no route required), Climb Explorer, multi-band GNSS, Power Guide, course deviation recovery. The 840 is the right answer for multi-day tour riders and Club ride enthusiasts. JoyVelo internal testing, 1,500 km road + gravel + MTB.
The Zwift Cog is a single 14-tooth cog that replaces your bike’s rear cassette so multiple bikes (11/12/13-speed) can share one Zwift-Ready trainer without swapping cassettes. Paired with the Zwift Click controller, it delivers 24 silent, instant virtual gears that shift under load. V2 design adds adjustable chainline. $49.99 USD.
Garmin's 2026 Varia Vue is the first cycling headlight with a built-in 4K camera and incident detection. 600 lumens, auto-recording, and incident auto-save. $799.
Firmware v7.09 (and above) on all Pro spindle pedals boosts claimed battery life from 60 h to 160 h. We tested the update on a PRO MX2 over 6 weeks of road and gravel — the new runtime is realistic, the data is unchanged, and the update process takes 2 minutes.
The PRO MX is the SPD version of the Pro spindle — mountain bike, gravel, cyclocross. We logged 5,000 km on it across gravel and mountain bike setups over a year. The data was so good that the PRO MX is now our new SPD baseline for head-to-head testing.
Garmin's flagship rear radar now records 1080p video continuously. Three months of daily commuting shows it is the most complete rear-end safety system on the market.'
Is the flagship solar-charging bike computer worth the premium? A 600km brevet and 5,000km of mixed riding put it through its paces.
The mid-range Edge 540 punches above its weight with multi-band GNSS, 26-hour battery, and the same software as the flagship 1040.
Garmin's flagship multisport watch adds solar charging, dive mode, and a brighter AMOLED display. After 6 months of use across running, cycling, and swimming, here's the verdict.
The Magene T600 is Magene's first self-powered direct-drive smart trainer at $899. ±2% accuracy, 20% max grade, no mains cable.
The Tacx NEO 2T brings self-powered operation, road feel, and ±1% accuracy to the mid-premium tier. A long-term review after 1,200 hours.
Garmin’s dual-protocol chest strap has been the industry reference for years. Here is what three winters of daily use look like.
No magnets, no cables, no fuss. Wahoo’s RPM sensors attach in seconds and just work across every head unit on the market.
The Apple Watch Ultra 2 is Apple’s flagship outdoor watch — dual-frequency GPS + 36-hour battery + titanium case. $799.
No camera, no fuss. The RTL515 is the radar-and-light combo that has been keeping road cyclists safe for years, and it is still the value pick.
The third-generation 4iiii left-only power meter delivers ±0.5% accuracy at a price that beats every crank-based competitor.
The Assioma DUO remains the reference pedal-based power meter: rechargeable, dual-sided, and accurate enough for pro-level training.
Scott pushed the Addict RC to an extreme 5.9 kg lightweight, and offers lifetime frame warranty + lifetime service.
The Bontrager Aeolus RSL 62 is Trek’s in-house premium aero wheel — 62 mm rim depth + OCLV carbon + DT hubs. $3,000 / pair.
Garmin's premium chest strap adds running dynamics, advanced running metrics, and dual Bluetooth/ANT+ transmission. Worth the $129 price?
The Wahoo TRACKR is the company’s first rechargeable chest-strap HRM, replacing the discontinued TICKR family. 100-hour battery (rechargeable, via magnetic USB-C cable), ANT+ + 3× Bluetooth Smart, IPX7, $89 USD. Tested 3 weeks across indoor cycling, outdoor cycling, strength training, and Zwift. The strap is the best Wahoo has shipped in years.
Replaces the 6-year-old RTL 515. USB-C finally. 170m official detection range (verified to 224m in drone-validated testing). 60° beam angle. Same-speed tracking is best-in-class. Lane detection + vehicle classification on Edge X40/X50 (Secure Bluetooth, EU mandate). No false positives in 6 weeks of real-world riding. Radar-only mode gives 25h battery. User-replaceable battery via T2 Torx. $299 (up from $199). JoyVelo internal testing, 6 weeks, 200+ km road + 100+ km MTB + multiple bus-route tests.
3.5-inch 1000-nit transmissive LCD, 480x800 resolution, 64GB storage, real speaker with electronic bike bell, Group Ride, hazard reporting, Garmin Pay. The bigger screen and faster processor justify the $699 price — if you can live with 20-hour battery instead of 1040’s 35-hour. JoyVelo internal testing, 1,800 km.
The Garmin HRM 200 is a 2026 chest strap that replaces the 6-year-old HRM-Dual. Headline upgrades: a physical button + bi-color LED for open vs secure mode indication, a child-safe quarter-turn battery door (tool built into the strap slider), secure BLE pairing for EU health-data privacy compliance, 3 ATM water rating, and two size options (XS-S, M-XL). Heart rate accuracy is on par with the Polar H10 reference across running, cycling, strength training, and Ski Erg. No onboard recording, no running dynamics. $79 USD ($20 premium over HRM-Dual).
The Magene T500 is a 2nd-gen direct-drive trainer at $699 USD: ±1% accuracy, 2200W max, 20% max grade, 88 N·m peak torque, and pre-installed Shimano 12-speed cassette. The headline weakness: no native virtual shifting and a flywheel-slip limitation at low gear ratios. Both can be solved with the third-party QZ App, which pairs the T500 with the Zwift Click.
The Magene T600 Eco is the 2025 Eurobike flagship direct-drive. 110 N·m peak torque, ±1% accuracy, 10 Hz Race Mode, 2800W max, 27% max grade, Wi-Fi + Ethernet, self-powered (3 min pedaling = 7 min flywheel energy), USB-C PD 20W. $899 undercuts KICKR V6 ($1,049.99) and NEO 3M ($1,999). Caveat: no native virtual shifting.
The 2019 Garmin Edge 830 paired a 2.6" touchscreen with the 530's button layout. Still a strong buy in 2026 at $399 if you can find it.
The Garmin Varia UT800 delivers 800 lumens with Edge auto-brightness integration. 1.5h on high, IPX7, $199. Still the smart headlight benchmark in 2026.
In our head-to-head testing with the Favero Assioma Pro RS, the spider-based Magene P515 matched peak sprint wattage to within one watt (1257 vs 1257, 1309 vs 1308) and showed no cadence dropouts, no residual torque, and no ANT+ sticky-watt artifacts. For a $229–$549 spider, that is unheard of.
COROS's mid-range watch delivers 80% of the Fenix 8's capability at 35% of the price. After 4 months of testing, here's the comparison.
Campagnolo launched the 13-speed Super Record Wireless in 2024 — the only big-three brand still keeping Italian hand-assembly for its high-end groupset.
The COROS Vertix 2 is sold on 60-hour GPS battery + dual-frequency GNSS + all-round sport modes. $649, 25% cheaper than the Garmin flagship.
1.2" AMOLED touchscreen (1500 nits), 22mm quick-release band, 40g (silicone) / 32g (nylon), 6-day AOD / 15-day lift-to-wake battery, Gen-2 optical HR sensor, microphone for voice memos, 60+ sport modes, no speaker, no offline maps, $249. JoyVelo internal testing, 4 weeks, 200+ km.
Wahoo's KICKR ROLLR is the wheel-on roller-based smart trainer that now broadcasts a native estimated power signal after the 2025 firmware update — no separate power meter required. The estimate is not lab-grade (±1%) and is highly dependent on gear ratio and rider weight, but in a mid-range gear (“Goldilocks zone”) it tracks a reference power meter within a few watts. Original $799 launch price has dropped to $699 at retail.
The Garmin Tacx NEO 3M is the 2024 Tacx flagship. The ‘M’ stands for Motion: built-in 49mm front-back and ~5° side-to-side motion plates integrated into the chassis (no accessory), plus 32-magnet road-feel vibration. ±1% accuracy, ERG mode is the new benchmark. $1,999 USD. Caveat: no built-in Wi-Fi ($129 adapter required).
The 2020 Garmin Edge 1030 Plus brought a 3.5" touchscreen, 24h battery, and Trailforks integration to $599. Now superseded by the Edge 1050, but still on the used market.
The 2019 Garmin Edge 530 brought multi-band GNSS, ClimbPro, and a button-only interface to $349. Still competitive in 2026 for button-first riders.
GoPro's latest flagship adds 5.3K 60fps, better stabilization, and modular lens options. After 1,000 km of cycling footage, here's what matters.
Garmin's second-gen speed and cadence sensors are small, lightweight, and ANT+/Bluetooth dual-transmit. Worth upgrading from the original?
The JetBlack Victory is the 2025 Australian direct-drive that sets a new sub-$500 benchmark. After 420 km of testing against Favero Assioma DUO, reproduces power within ±2%. 1800W max, 16% max grade, Wi-Fi Direct, 10 Hz Race Mode, sensor bridging. Ships pre-installed with Zwift Cog v2 + Click. At $399, undercuts KICKR Core 2 by $150.
The Tacx NEO 2T (2019) is a mid-cycle update to the NEO 2: native 12x142 / 12x148 thru-axle, 25% max grade, 2,200 W max resistance, redesigned neodymium magnet array that resolves the "virtual tire slip" issue at low flywheel speeds. ±1% claimed accuracy, no calibration required, ANT+ + Bluetooth Smart. The benchmark direct-drive trainer of the late-2010s.
No screen, 7-day battery, 50m water rating, optical HR + SpO2 + skin temp + ECG-style AFib detection, magnetic Pebble core clips into a choice of three bands, $99 launch with no subscription required for core data. JoyVelo internal testing, 4 weeks, ~150 hours of wear.
First Wahoo radar. $199, 150m detection (vs Garmin RTL 515 140m), USB-C, 99g, 35° beam (vs Garmin 40°), ANT+ radar + ANT+ light, brake mode, side-LED visibility, 0 false negatives in 1 week of real-world testing. 19h solid / 12h peloton / 6h day flash / 5h night flash (claimed). The biggest miss: the quarter-turn mount is 1mm thicker than Garmin, breaking 10 years of third-party mount ecosystem compatibility.
3.2-inch AMOLED touchscreen (the best screen contrast in the category), processor + storage + RAM all doubled, 12.5-13h real-world battery, louder buzzer, and a new companion app. SIM card slot removed. JoyVelo internal testing, 1,500 km road + gravel.
Bryton's first rear radar focuses on Garmin compatibility and long battery. Four weeks of testing shows it is a credible mid-range option.'
The Magene C706 brings a 2.8" color touchscreen, multi-band GNSS, and 25-hour battery to a $329 price. A serious Wahoo competitor.
Trek's CarBack is the first credible challenger to Garmin's Varia RTL515 in the radar tail light category. After 3,000 km, here's the comparison.
Bryton's new flagship is half the price of Garmin's Edge 1050, with comparable screen, GPS, and battery. After 2,500 km of testing, here's where it wins and loses.
180g rear light + ANT+ radar. $180 radar / $125 front light / $280 combo. 146m detection (verified), 35° beam (vs Garmin 40°), 0 false positives in 3 radar trouble spots, threat persistence on slow-moving cars, brake light (sensor-based), 300 lumens solid max, 20h battery (claimed), Lezyne Strip Drive strap mount (no quarter-turn, so NOT compatible with Garmin third-party mounts). JoyVelo internal testing, 3 weeks, mixed road + suburban.
2.7-inch transmissive LCD, real speaker with electronic bike bell, 7 physical buttons, 5Hz MTB recording, Garmin Pay, 64GB storage, and weather overlays. The new screen cuts real-world battery to 10-12h. JoyVelo internal testing, 1,500 km across road + MTB.
The Wahoo KICKR Core 2 is the 2026 successor to the 7-year-old KICKR Core. Same mechanical package (1800W, 16% max grade, 22 Nm) but fully refreshed electronics: 2.4 GHz Wi-Fi, 10 Hz Race Mode, KICKR Bridge sensor hub for HR straps and Zwift Click v2. $549.99 MSRP, $350 less than 2019 v1.
Our two-round test of the second-generation XCadey X-Power S GEN 2 spider found it can drift 18W mid-ride, lose sprint peaks to a cadence dropout, and shift zero offset on every gear change — a power meter that passes the spec sheet on paper and fails the data-integrity check in practice.
iGPSPORT's first rear radar includes a 1080p camera at a $249 price point. Three weeks of testing shows it is the most affordable radar-camera combo on the market.'
The iGPSPORT BSC500 brings a 2.6" color touchscreen, multi-band GNSS, solar charging, and 28-hour battery to $279.
Zwift's first smart trainer delivers ERG-mode accuracy comparable to the KICKR Core at a $599 price. After 4 months of indoor use, here's how it stacks up.
41mm $349 / 45mm $399 (LTE +$100), 3000-nit AMOLED curved display with 16% smaller bezels, dual-chip architecture (25% faster / 50% lower power), 2-day battery (45mm), 14-15h GPS, two-way satellite emergency SOS via Skylo (US only, LTE model required), Gemini AI assistant, repairable battery (EU regulation), dual-band GNSS, Fitbit health platform. JoyVelo internal testing, 4 weeks.
The 2018 Garmin Edge 520 Plus brought maps, incident detection, and Strava Live Segments to $249. Discontinued in 2022, but still on the used market at $80-$120.
The 2020 Garmin Edge 130 Plus is the smallest Edge with a 1.8" display, 12h battery, and $199 MSRP. Still the go-anywhere compact unit.
Sigeyi brings carbon-fiber dual-sided power cranks to the mid-price market. Tested against the Quarq DZero and the Magene P515, it lands in an interesting middle ground.
Wahoo’s second-generation Roam brings dual-band GPS, 17-hour battery, and a color touchscreen that challenges the Edge 540 head-on.
The iGPSPORT BSC300T brings a 2.4" color touchscreen, offline maps, and 22-hour battery to $229. A strong Bryton competitor.
Wahoo’s first new HRM since 2021 adds onboard memory, 100-hour battery life, and a sub-$90 price tag that undercuts Garmin.
The Magene C606 brings color touchscreen, ANT+/BT, and 20-hour battery to a $199 price. The new budget benchmark.
SRAM’s Quarq DZero delivers dual-sided power from a hidden spider, with 200-hour battery life and ANT+/BLE in a weather-sealed package.
Power2Max's PM-Dual offers ±1.5% accuracy with left/right balance at $799 — undercutting Favero and Garmin by $300. Does the cost-saving come with real compromises?
The wheel-off KICKR Core brings direct-drive accuracy and 12% max grade to a price point that was unthinkable five years ago.
Wahoo’s SPD-SL power pedal brings dual-sided measurement, replaceable batteries, and cycling dynamics to a more accessible price point.
Polar's arm-band optical HRM promises chest-strap accuracy without the chest strap. After 200 hours of testing, how close does it actually get?
Lezyne's flagship front light hits 1000 lumens at $99 — undercutting Garmin and Bontrager by 50%. Does the price savings come with real compromises?
The Decathlon Van Rysel D100 is a $249 direct-drive trainer that is a rebadged Magene T110. ±5% claimed accuracy (real-world ±1.5–2%), 600 W max power, 6% max grade, Bluetooth FTMS only, no cadence broadcast, no ANT+. Tested 4 months across 2 units, including the Zwift Cog and Click edition. The best budget direct-drive trainer in 2024–25, with caveats.
41mm $549 / 45mm $549, AMOLED 2000+ nits (shared with Forerunner 570/970), metal case (vs Venu 3 bezel-only), 2 buttons + touch (down from 3), LED flashlight (4 white + red), FDA-cleared ECG + AFib, Lifestyle Logging (free for all Garmin users), shared OS with Fenix 8 / Forerunner 570/970, 80+ sport modes, dual-band GNSS, Mix Session multi-sport.

The Wahoo TICKR Fit is an optical arm-band HRM that pairs ANT+ and Bluetooth. Tested against the Polar H10 reference.
The Binavi Air brings a 2.2" color display, ANT+/BT, and 18-hour battery to $129. The cheapest real bike computer in 2026.
Apple's flagship watch has great hardware but limited cycling-specific features. After 6 months of testing, here's who it's for.
Elite's entry-level direct drive trainer hits a $449 price point with reasonable accuracy. After 800 hours of indoor use, here's the breakdown.
A long-form review of the Wahoo TICKR Fit optical armband HRM. ANT+ + Bluetooth, 30-hour rechargeable battery, IPX7, $79 USD. Tested 3 months across running, indoor cycling, mountain biking, strength, and rowing. The strap quality is a real concern; the sensor data is genuinely good.
Our two-month test of the Magene P715 SPD-SL found dual-sided power within 2-3W of a Power2Max NGeco reference across every dataset, with 120h battery, IPX7 sealing, 322g measured weight per pair. The catch: a vendor-confirmed pedal-phase bug that locks start angle at 0° (fix promised by end of April 2026). At $499.
The 2024 Wahoo KICKR MOVE adds a fore-aft motion deck underneath the 2022 KICKR V6 hardware. ±1% power, 20% max grade, 2,200 W, 5.4 kg flywheel, integrated motion lock. $1,599 USD. We tested 1 month of solo + partner riding vs a third-party rocker plate reference.
Slightly larger LTPO3 display, 5G with dual antennas, two-way satellite emergency SOS (US/CA/MX), Find My over satellite (18 countries incl. EU), 14h GPS verified in a 70km / 14h50min mountain hike (Apple said 14h), Workout Buddy with pre/in/post-run voice coaching, WatchOS 26 sleep score. JoyVelo internal testing, 4 weeks, 4 weeks of daily wear + 70km mountain hike + 8 training activities.
Free update for Apple Watch Series 10 / 11 / 12, Ultra 2 / 3, SE 3. Workout Buddy now runs independent of the iPhone (offline voice alerts for runners). Sleep app gains cross-timezone support. Find My consolidates devices, people, items into one map view. Women’s health adds perimenopause tracking. Siri gains a dedicated app + cross-device sync. The catch: Apple Watch Series 9, Ultra 1, and SE 2 are dropped from the support list — a 3-year support window that mirrors Garmin and erases Apple’s historic 5-6 year advantage.
42mm $429 / 46mm $479, MIP display + sapphire glass + titanium bezel, dual-band GNSS as standard (previously APEX 2 Pro only), dual mics with wind-noise reduction + real speaker for Bluetooth calls, depth meter (no dive certification), customisable Action button, 32GB storage, 30x faster map rendering, depth meter bug fixes pending. JoyVelo internal testing, 4 weeks, 70km hike + 200+ km running + 1 open-water swim.
AMOLED display standard, microphone + speaker for calls and offline voice, dive to 40m with leak-proof inductive buttons, redesigned UI merging all Garmin watch lines, solar ring replaces panel, training-readiness 2.0. $999 launch is $200 over the Fenix 7 and $100 over the Epix Pro. JoyVelo internal testing, 4 weeks.
7 physical buttons, no touchscreen, no speaker (only a buzzer), no Garmin Pay, 32GB storage, transmissive 2.7" LCD, and 5Hz MTB recording shared with the Edge 850 and 1050. The 12-hour real-world battery is a serious regression from the 26-hour Edge 540. JoyVelo internal testing, 1,200 km.
208g (heaviest bike computer on the market), 3.8-inch touchscreen, real speaker with electronic bike bell, integrated wind-speed sensor, 10-15h real-world battery. But TrainerRoad / Xert unsupported, Strava Live Segments missing, no TrainingPeaks auto-upload, route sorting missing. JoyVelo internal testing, 800 km.
MIL-STD-810 rugged plastic case, integrated flashlight (4 white + red brightness levels), 1.2" MIP display, single-band GNSS, older optical HR sensor, Polar OS shared with Vantage M3 / Vantage V3 / Grit X, 3-4 day battery with AOD. JoyVelo internal testing, 4 weeks, 200+ km of running + cycling + hiking + swimming.
MIP touchscreen, multi-band GNSS, ANT+ + Bluetooth, solar top-up, 97g. Officially 120h battery. In real-world testing the solar panel actually LOSES charge in the sun; the device routed the famous Stelvio climb as 3 separate segments; offline route re-planning draws a straight line to the destination. JoyVelo internal testing, 600 km.
Cheapest bike radar on the market at $89. 40° beam, USB-C, ANT+ radar + light, brake light, ANT+ light control disable option. JoyVelo internal testing on 20+ km of road reveals over 20 false positives, missed vehicles, and ghost cars. The radar is fundamentally broken in real-world conditions and should not be sold. JoyVelo internal testing, 3 weeks, 100+ km of mixed road + suburban + urban.
Our first-ride test of the SIGEYI AXO SL spider reproduced a sprint-cadence-sensor failure that renders the power data unusable under hard acceleration: the cadence sensor drops to zero under >1000W load, and the power calculation follows it to garbage. Same failure mode that plagued early Garmin Rally 200 / Vector 3 pedal PMs. 79g, $376 USD. Skip.
Our two-round test of the ThinkRider PP5 spider found it can drift 18W mid-ride, lose sprint peaks to a cadence dropout, and shift zero offset on every gear change — a power meter that passes the spec sheet on paper and fails the data-integrity check in practice. The PP5 shares firmware 1.68 with the Coospo S10, the same 1.72 update bug, and the same Easton Cinch crank interface. Skip.
Our cross-test of the Coospo S10 spider against an Assioma Pro RS and a Garmin Rally RS200 reproduced the same hardware-level residual-torque defect that got the ThinkRider PP5 a skip recommendation — plus a 1-second data-transmission delay. The S10 and PP5 share firmware 1.68 and the same Easton Cinch crank interface. At $88, the cheapest spider PM has the least trustworthy data.
Our two-unit cross-test of the Elilee EK01 spider — aluminum first, then the $1200 AUD carbon as a control — reproduced the same catastrophic failure on both: 4-5 second power/cadence dropout under sprint, residual-torque effect requiring manual re-zero after every hard effort. We paused testing and sent data to the vendor; no fix committed. Skip.
Training software, fans, mats, and indoor cycling accessories reviewed with the same protocol-level rigor as our hardware reviews. Zwift vs TrainerRoad vs ROUVY coming up.
