"The group's 264 gram eleven speed cassette stands out prominently. Except for its largest cog, which is aluminum, the entire one-piece unit is machined down close to its final shape (minus the teeth profiles) from a steel ingot, a process that takes place in a single, labour intensive step. Shifts are quick and precise, with XX-like chain movement across the cassette even under load. We were never at a loss for gears despite having just one chainring., none of the individual jumps on XX1's massive 10-42T cassette are disruptingly big, and they're admirably even across the spread". bikeradar (rewiev)
Ranging from 10- to 42-tooth, the 11-speed X-DOME™ delivers an incredibly wide gear range while maintaining even, optimized steps. The single-unit cassette combines with the XD™ Driver Body for a superior connection to the wheel.
