For Sale Shimano BB-UN91 / XTR Bottom Bracket

[Monkeeee01]

£50 + P&P

In mint condition. I don’t think it’s ever been used, I installed it to find it was too short for my set up

Shimano BB-UN91 / XTR Bottom Bracket. B.C 1.37, 68, 115mm. (DH marking on spindle that defines 115mm)

 

[Once A Hero]

Thought they only came in 107mm and 113mm lengths?

I think you are right from a quick google.

I’ll get my callipers out and measure it tonight and update

I'm tempted to buy this because i'm about to do a full M900 XTR build on my 92 Kona Explosif. Thing is I don't know what size length axle i need,the bb is 68mm width on the Explosif and i'm using M900 cranks with M900 hubs on the wheels.
Any idea if this one is the correct one to use, just because i don't want to spend £50 then find out it's wrong.

Cheers
