so im looking at scoring a m950 crank set off the bay for my lady’s mtb tourer im in the middle of wasting all my time obsessing over,
but it dosn’t come with a bb
now they use the octalink v1 bb’s, yes?
ive seen a few floating about on ebay but was wondering will they work with the more modern v2, that happen to be cheaper? and more accessable?
will it work with any octalink bb? road or mtb only? other than the v1 or v2 is there anything else i should be worried about with sorting a bb out for it?
I would either keep an eye for a square taper crank set, there are occassionally 110/74 bcd triples on ebay from 90’s MTB’s or just buy new hollowtech deore cranks.
I am 99% they would work in terms of crank/bb spline interface, but only coming in two spindle lengths, means you might wanna do some careful measuring of your frame to see if you’ll get chain stay / crank clearance…
for the hassle and cost I’d just go new (or square taper 2nd hand) to be honest
e.g. a brand new set of deore cranks can be as cheap as $70 (incl BB), I know its ext BB and that might not be great for looks/q-factor but it does come in silver.
according to mombat.org the xtr m950 and m952 bb’s came in 112.5 and 116mm spindles, so surley the 118mm spindle would fit if not give me a touch more room, and i doubt very much courts will ever be putting it in the big ring for very long
Did some sleuthing and read that early model MTBs often had 73mm BB shells. Sorry I thought it was a Downhill/freeride STD. My bad. FWIW 73mm and 68mm have the same BB diameter (both are English).
arggghhh my bad i thought that was the shell size, si its the width hey???
i’ll have to do some measuring when the frame lands,
its a vintage fully ridged mtb, got all the mounts and such i need to make it in to a versatile little winter bike/tourer for my lady
