The Grafton B/B is a well crafted dual adjustable fixed spindle B/B type with extra contamination seals and a Titanium spindle. The spindle is machined from Titanium rod, with tapered ends so the arms slide on easily. Turned on a lathe, the spindle has a smooth 17mm diameter where the bearing sits on it, and a raised shoulder for it to rest against as the cup is tightened. The spindle is drilled through to reduce excess weight and tapped for the crank bolts. The bearing cups are flawlessly machined from aluminum rod. The inside of the cup is drilled to accommodate the bearing cartridge and spindle. The outside face of the cup is given a polished, convex surface with six equally spaced holes for pin spanner use in making the final cup adjustments. There are three aluminum pieces to the lockring, which are sandwiched together. The outer aluminum piece is threaded with six equally spaced cuts for the lockring spanner. Behind this is a thin, non-threaded aluminum ring, with another thicker, non-threaded aluminum ring.
