3. ASSEMBLY METHOD AND REQUIREMENTS
(CONTINUED)
3.3 Mounting the rotor to the hub
1. Remove the wheel from the bike. Attach the rotor to the hub with the supplied Torx bolts and tighten with a T25 Torx wrench.
Final tightening torque: 6.2 Nm.
2. Make sure the side with Tektro logo is facing out (rotor must rotate in the same direction as wheel set).
Tighten rotor screw then install the wheel on the front fork or frame.
Note: The rotor must be installed with the“rotation”arrows pointing in the same direction as the forward rotation of the wheel.
3.3.1 Mounting the adapter and caliper
1. Mount the relevant adapter to the caliper body. Insert 5 mm bolts through the two adapter slots on the body
and screw into the holes on the adapter. Do not tighten yet.
2. Mount the caliper body and adapter to the frame/fork by placing the slot in the caliper body over the rotor.
The mounting holes on the adapter should be behind the frame/fork mounting holes (the hub side).
Screw and tighten two 5 mm Allen bolts into the upper and lower holes in the frame/fork mount.
Final tightening torque: 6-8 Nm.
3. Check that the rotor is centred between the disc brake pads, and tighten the two bolts holding the caliper to the adapter.
To re-adjust the caliper positioning, loosen these two bolts and slide the caliper over until it is centred on the rotor,
then re-tighten the bolts. Final tightening torque: 6-8 Nm.
