The ThinkRider PP5 Power Meter Spider & Carbon Crankset is praised for its affordability and reliable steady-state power data, making it an excellent entry-level option. However, reviewers consistently report accuracy issues during high-torque sprints, residual torque drift, and compatibility limitations with certain cranksets, indicating that it may not suit competitive sprinters or those with non-standard setups.

Reviews & Ratings
14:11The reviewer purchased the ThinkRider PP5 Power Meter Spider & Carbon Crankset with their own money to test its performance. They installed it on their bike and tested it on a climb called Bansong Gogae and on flat roads. They found that the power data was stable with no spikes or false readings, and they even achieved a personal record on the climb despite the added weight. They concluded that at the price point of around 130,000-140,000 KRW, the performance is impressive and suitable for those looking to enter power meters.
14:20The reviewer tested the THINKRIDER PP5 Carbon Fiber Spider Power Meter Crankset over several months, finding it accurate for steady-state riding and pacing climbs, but noting drift issues during maximal sprints. Despite concerns about AliExpress reliability, they consider it excellent value for most cyclists.
The THINKRIDER PP5 is a dual-sided power meter spider with Easton interface, available as standalone unit or bundled with carbon or aluminum cranksets. Users report prices ranging from $80-290 USD/EUR depending on configuration and sales. The carbon crank version weighs 486g and features a titanium DUB spindle, while aluminum versions have steel spindles. The power meter claims ±1% accuracy with 300-hour battery life and uses ANT+/Bluetooth connectivity. It requires the ThinkRider Tools app for firmware updates and calibration. Compatibility is limited to Easton interface cranks; it is not compatible with Riro Acrossfire, Senicx PR3, standard Red DUB, or CUES FC-U6030-2 cranksets without modifications. Firmware v1.9.1 has been released, but independent testing confirms residual torque drift issues persist after high-torque efforts, and the manufacturer acknowledges a hardware issue that may require a future product revision. Some users report a ~3 second power data delay when paired with iGPSPORT BSC200. Chainline issues and bolt length concerns have been noted with double chainring setups.
