The Tracker front wheel hub is built with the same design as the White Ti front but with a larger axle for front suspension use. The hub shell is machined and polished similar to the Ti front. However, the Tracker has an outer diameter of 34mm in the axle area, larger than the 28mm of the Ti front. It uses larger Japanese IJK 6903RS bearings, pressed into each hub side. The Tracker features a Cro-moly steel axle with a 17mm outer diameter and a 15mm inner diameter, unlike the 12mm Ti axle of the Ti front. The machined aluminum axle end cap is bonded to the axle, providing a 20.3mm contact surface, and then reduced to the 9mm diameter axle required for the fork blade. A locking collar, also with two 2mm set screws, secures the axle in place. Similar to the Ti front, a machined aluminum axle end cap is used to complete the hub. The White Tracker front has a 48mm hub flange diameter, with 70.5mm spaced flanges. The spoke holes have a 40.5mm center circle diameter, and it is available in 32 spoke hole drilling. The entire front wheel hub has a shiny silver finish.
