Reviews & Ratings

The reviewer presents a new product from XM Carbon Speed, a set of carbon cranks featuring a 24mm titanium spindle designed for Shimano drivetrains. They highlight its key features, including the titanium spindle for added strength and weight savings, the use of a Shimano-compatible standard instead of the more common SRAM DUB, and its in-house design. The reviewer provides the weight (343g), compares it favorably to a Shimano 105 alloy crank (565g), and details its price ($340 USD), available lengths (170mm, 165mm, 155mm), and included accessories like spacers and pre-applied thread lock.
