## Description

SHIMANO - Bottom Bracket BSA 122.5/68mm-BB-UN300 Square Taper (LL123)

Review: Nice bottom bracket. Good price. - I had mechanic fit bottom bracket, cost me £50 and the crank came loose, whilst cycling. desertcart AI told me which bottom bracket would work, and it seems excellent fit. And I got the tool to fit it also, for around £24 total, so good deal. Working perfect.
Review: Good buy - Very happy customer will buy again
