PRODUCT INFORMATION
The SRAM RED AXS Power Meter Kit E1 builds Quarq power measurement into one-piece direct mount chainrings, for riders who want accurate power data from a light, stiff, durable unit. It reads within +/-1.5%, is not affected by temperature changes during a ride, and measures left and right leg balance.
Every chainring pair has a 13-tooth gap for crisp front shifts and a gentler change in cadence. It fits SRAM 12-speed road cranks with the DUB spindle interface. Choose 46/33T for climbing and mixed terrain or 56/43T for big-gear time trial and triathlon speed.
