Post subject:  Bottom bracket grumbling
My bottom bracket is making a loving grumbling noise (nothing to do with all the mud and wet weather we have been having :lol: honest), thing i need a new one but strugging with sizes/names off every thing. According to commencals website i have got a SRAM S1000 Press-fit 39/26 crank, frame details says its designed for PressFIT BB92
bottom bracket.

Search for a "bb92" and it only comes up with http://www.chainreactioncycles.com/Mode ... elID=51397
Search for "pressfit" and it comes up with £100+ bottom brackets!

Whats what?

Have you tried removing and refitting it?
mine was making some grumblings so i took the crank out cleaned the axle and popped it back and the grumbling stopped

This looks like the one i have got (from what i remember when i have removed my crank before). I guess when you have an expressive bike, everything is expensive for it =(

I would of though they would have said its wear and tear and not a warranty issue, as i said, it's only from what i rememeber. Not doing anything tonight so may wip the crank off tonight and check to see if theres any numbers for refences.

Right whipped off both cranks.

Bad news, one bearing seams fine, the other is like a bag of bolts. New one it is then.
Good news, it says its an Truvatic GXP (not super duper £150 joby but £30) on it so would of thought i would need
