World Class / GT Hadley Titanium Square Taper Bottom Bracket: 111mm x 68mm - 167g (MINT)
The Hadley-made GT BB & World Class BB were the first high end aftermarket units to use the Shimano/Park cartridge BB removal tool. Both were extremely similar in design. The GT usually has a blue anodized center shell, and the World Class usually has a black one. This one is identical to both, but the center shell is silver anodized. Perhaps this is an early model for either brand?
Mint barely used shape. Bearings are buttery as new, spindle tapers show almost no installation marks. Cups and center shell are clean.
