PowermeterMagene PES P515 Power Meter Set 4 Bolt 110BCD 24mm Cadence Pedal Balance Ant Steel Spindle Crankset Chainring for Shimano Sram
Created: July 04, 2025The reviewer purchased the Magene PES P515 power meter crankset from AliExpress for £225 to improve their winter training. They were greatly impressed with the results and found no downsides. The reviewer found installation straightforward as a direct replacement for their Shimano Ultegra crankset. They tested the power meter's performance against Wahoo Powrlink dual-sided pedals and found the data to be accurate, consistent, and reliable, though it read slightly higher. The crank stiffness was comparable to Ultegra, and the shifting performance of the chainrings was very good, nearly matching Shimano's gold standard. The reviewer concludes it scores really well, especially considering its significantly lower price compared to competitors.
