Park Tool BBP-1.2 Dub Adaptor 2292-2

Bottom bracket bearings for 30 mm spindles use 2292-2 drifts. It is important to first install any other drift from the BBP-1.2 against the handle assembly before using the 2292-2 drifts (see image gallery). This extra drift prevents the smaller (DUB/28.99 mm) side of the 2292-2 drift from contacting the handle press plate and being pushed into the handle.
