SRAM Rival AXS E1 DUB Power Meter Crankset

The SRAM Rival AXS 1 E1 DUB Power Meter Crankset combines lightweight aluminum arms with a discreet, spindle-based power meter that measures left-side power to calculate total output. With a long-lasting AAA lithium battery offering over 400 hours of ride time, the system is waterproof to IPX7 standards and adds less than 40 grams compared to a standard crankset. It features a wide chain line for Full Mount derailleur compatibility and a direct mount chainring with SRAM’s X-SYNC technology for precise chain control. The DUB bottom bracket interface ensures durability and simplicity across a wide range of setups. This crankset is an advanced but affordable way to improve cycling performance.
