Hi, just checked and my bbs are for 68mm shell. Sorry about that

 

[baron von greenback]

No worries cheers anyways I do need one for a Indian fire trail I measure and let you know unless you know

 

[carlhcyc]

Err.. not sure on marin bb shells. But I have a lot of different axle lengths for 68mm frames if it turns out to be that

 

[baron von greenback]

Just measured it it is 68mm but I don't know what length I need

Depends what crank you're intending to use. XT FC M730 (and DX, LX, deore equivalents) would be 122.5-127.5mm. Slightly later low profile cranks like LX FC M560 would be 113-118mm. Later still micro drive cranks (22/32/42 chainrings) would be 107-113mm. The shorter options give 47.5mm chainline (ideal), the longer options give 50mm chainline.

What era is the frameset? And what crank do you have?
