Enhanced Stability and Handling: Long chainstays and extended frame reach provide exceptional traction and load balance for confident off-road rides.
Shifting Options for Every Rider: Frame setups include Shimano GRX, Pinion C1.12, Pinion SmartShift, or electronic Di2 for smooth, reliable gear changes.
