What cranks need 125mm bb?

[Martin]

Need some cranks for my Attitude and as Cook's are going skyhigh at the moment I am looking for replacement.

As far as I know XT M730 takes 125mm and Ritchey Logic.
Is this true and are there others??

Help would be really appreciated.

Cheers,
Martin

AC first type if I'm not wrong... However I'm using a 125 BB on a forced AC crank which requires a 110mmm. In fact, I'm using a double chainring, and need to push the middle ring outwards to get a decent chainline with the 11t cog... You might think about a double chainring setup too...

XT M730 takes from 122.5 to 127.5 (68x122.5 with mine on the KHS)

I had a few Shimano & Suntour catalogues which gave the required BB lengths in them, but I've lent them to Fluffychicken to scan them, so I can't check any others out at the mo.

Hi Martin,

The non-MicroDrive SunTour XC Pro bottom bracket was 125.5mm, so I'd presume that's what the corresponding cranks need on a 68mm BB shell.

All Shimano MTB of that era before XTR.

RaceFace should be the same (none LP)

Pretty sure the ritchey logics take 120mm. At least that's what came on my '92 bridgestone mb-1 and '94 ritchey p-21, both 110bcd and original bottom brackets.
