Install the stem on the cartridge, then align the stem with the shim slot and the front wheel. Torque the stem according to the manufacturer specifications. Install the brakes.
Install the top cap, then torque to 18 in-lbf (2.0 Nm).
Fig.8:
Adjust the two preload screws (K) using a 2mm Allen key, until they both contact the compression ring. Gradually and evenly alternate between the two preload screws while engaging
the front brake and rocking the bike back-and-forth until any movement/looseness is eliminated and the headset rotates freely.
To access the preload screw (lower), the 2mm Allen key goes through the upper locking screw. The upper locking screw is tightened using a 2.5mm Allen key.
Fig.8:
Torque the upper locking screws (L, 22 in-lbf (2.5 Nm)) down onto the preload screws (K) below to lock the preload screws in place. DO NOT GREASE THE LOCKING SCREWS!
