Bushnell Lightweight Eccentric Bottom Bracket


Bushnell Lightweight Eccentric Bottom Bracket

Stock Status: In Stock
High end eccentric lightweight bottom bracket shell for tandems or single speed frames.
Bikemonger says... Very clever mechanism that makes this the choice for many when replacing their rubbish creaking EBB. Two wedges move away from each other, from the centre outwards, causing the whole BB shell to expand.

It ain't cheap, but nothing else works like this, What do you want, creak free chain adjustment, or £50 in your pocket and a cruddy BB that needs constant attention?

Bushnell says.... The Bushnell Eccentric Bottom Bracket is the industry leading design for chain tension adjustment on tandem and dedicated single speed bikes equipped with eccentric bottom bracket shells.

The lightweight version features additional machining and drilling of the alloy body to reduce weight.

Accepts English threaded bottom bracket cups (1.37 X 24 tpi)
Lightweight, cut-out body design made from aluminum
Fits BB shells from 53.8 - 54mm I.D. without shim
Standard width (68mm)

Expensive but . . . highest quality engineering that ends all EBB problems forever. Fitted mine using plenty of copper grease. NEVER slips, NEVER welds to frame, NEVER knocks grinds or clanks! Worth every penny. Would definitely buy again but won't need to as it will last forever.
