12 moderately flared, medium width drop bar balances off-road performance, with on-road aerodynamics and comfort. Vibrocore foam core reduces transmission of harmful frequencies of vibration, and increases bar fatigue life and ultimate strength . Short 110mm drop and 65mm reach geometry is perfect for aggressive riding stance and long days in the saddle on mixed terrain. 31.8mm barclamp zone, and aerodynamic ergo top section enhances hand comfort over longer rides, without limiting range of rider/hand positions . 21.6mm inner diameter barends, allow use of most barend shifters.
