ACROS Blocklock Headset Lower Part 120° - 1.5 Inches - ZS56/40 - black

The semi-integrated ACROS Headset Lower Part integrates the innovative Block Lock steering limiter system (steering angle: 120°) to prevent frame damage due to handlebar or fork impacts. Cutouts in the upper cup guide a pin on the headset top cap and mechanically limit the steering. The impact forces at the steering limits are reduced by elastomer bumpers to increase the grade of protection. The Block Lock steering limiter is especially suited for super-light and delicate carbon frames.
