Dual-sided power meters used to cost as much as a new wheelset, but Magene completely flipped the script here. The 24mm spindle makes it a dead-simple, immediate upgrade for anyone running a Shimano groupset. You literally unbolt your 105 or Ultegra crankset, move your existing chainrings onto the P515 spider, and slide it straight into your current bottom bracket.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePrecision Spider Data.
