The White TI bottom bracket is a jewel-like marvel of a replacement B/B. The cups are made of machined aluminum, using precision sealed bearing cartridges for the bearing structure, machined Titanium crank bolts, and a TI 6-4 Titanium spindle. The bearing cups are made from machined aluminum rod, turned and cut on a lathe, drilled from each side for the bearing and spindle, then threaded for the B/B shell. The bearing cartridge is pressed in from the outer side and nestles against an inner lip in each bearing cup. Outside the bearing cartridge is a machined aluminum locking collar, that slides down the spindle and cinches down on the spindle using three recessed allen head bolts. These 2mm allen bolts are accessible through two small holes on the flat sides of the outer flange on each bearing cup. This locking collar fits in the bearing cup flush with the outer surface of each cup. This accessibility permits you to simply and easily "float" the spindle to the position needed for your crankset.

White also makes a Cro-moly spindle version of their B/B. The Cro-mo model uses the same bearings, bearing cups and locking collars as the Titanium model, but it doesn't come with crank bolts or anti-seize compound. The Cro-moly spindle is well machined from Cro-moly steel rod to a 17mm smooth outer diameter. The spindle is drilled through to reduce weight then the ends are tapped for the crank bolts. Crank bolts are not included. The bearing cups for this B/B are anodized Silver.
The White Cro-mo is available in English thread, with spindle lengths of 110mm, 112mm (XTR), 112 (XT), 114mm, 117mm, 119mm, 122mm, 125mm, 128mm, 132mm, or 135mm. The weight of the White Cro-mo bottom bracket with a 122mm spindle, (with no crank bolts), is 238 grams. USA
