Special Tools Needed to install
Recommend using Hadley 18mm and 15mm open end thin wrenches
or you can use a ParkTool 15mm PW-5 pedal wrench in place of the Hadley 15mm.
Recommend using Hadley Tools to remove existing end caps.
Re-dishing the wheel may be required since the axle on this adapter kit protrudes out 6mm more on the disc side than the drive side.
