The CLIQ integrated tapered headset is made from the same high quality machined aluminum parts and sealed bearings as our regular 1 1/8″ headset but the bottom bearing is increased to a 1.5″ size. The tapered headset headset also includes two lower bearing races to accommodate both 1 1/8″ steer tube and 1 1/8″/1.5″ tapered steer tube forks. 3 different size alloy top covers are included to achieve a variety of stack heights.
