Bullseye/Klein Press-Fit Bottom Bracket

This is the original solution from Bullseye which enables those who wish to install Bullseye 2-piece cranks on an early press-fit  bottom bracket Klein frame.

Simply remove your existing press-fit Klein bearings and replace them with these Bullseye cups instead.

The cups measure 35mm (OD) to fit a Klein bottom bracket shell and 22.2mm (ID) to fit the diameter of a Bullseye bottom bracket axle. Bearings are loose ball bearings covered on the outside by fibre board seals.
