The Wheels Manufacturing Headset Cup Drift is an essential tool designed specifically for use with the Wheels Mfg Headset Cup Press (PRESS-8). Crafted from machined aluminium, this drift features a 1/2-inch thru hole and stepped machining to precisely fit common headset cups with 1-1/8" (30mm) and 1-1/2" (40mm) bearings. Its robust design ensures reliable alignment and smooth pressing, making headset installation more efficient and accurate. While optimized for the PRESS-8 model, this drift may also accommodate other headset cup sizes, offering versatility in workshop settings. However, it is not recommended for use with Wheels Mfg PRESS-1 or PRESS-4 handles and rods, which have a smaller 3/8-inch diameter rod, as this can compromise the straightness of the pressed cups.
