Bullseye Rollerbracket and Open Bearing Bottom Bracket


The rollerbracket BB accepts JIS taper cranks: http://www.sheldonbrown.com/bbtaper.html
It uses roller (needle) bearings which dissipate the stress over a larger bearing surface area: http://www.bikepro.com/products/bottom_ … ulls.shtml
The early open bearing BB fits 1st, 2nd or 3rd generation 22.2mm spindle Bullseye 2-piece cranks.
The Euro to US adaptors shown are not made by Bullseye.
