Trek Knock Block Spacer-Set 1 1/8" 10mm black (3个)

The Knock Block Spacer Set for 1 1/8 "10mm

Knock Block - Trek's proprietary control bearing prevents the handlebars from twisting and the fork crown striking the frame. This new tax warehouse is used on almost all 2017 Trek models. In addition to the new control bearing special spacers and a special stem (with 2 notches on the bottom) are provided. With the help of the KNOCK BLOCK Lockring Spacer, this system can be mounted on any stem. This allows the KNOCK BLOCK to adjust the seating position and ergonomic settings. The lock ring is mounted as the top spacer under the stem.
