Mountain bike Crankset

You should be looking at short crank arms also.

Here in Aus we can buy 155, 160, 165mm arms with double chainring mounts with 110mm pcd. This would give a 34 tooth small ring and whatever you want for a big ring. I can post a pix if you want one.

No, I'm average (5'10"😉 and looking for 175mm narrower two chainrings mountain crankset.

Anyone else?

Good day,

I need help! Since many years, i'm looking(searching, in fact) for a mountain bike crank wich would be equipped with two chain rings (29/30x42). I know Coda for having been mounted on high-end cannondale scalpel model, few years ago, although I never saw anything equivalent since then.

The reasons of my interrogation is that I need it to reduce the Q-factor because of my narrow hauches - I'm a small frame, 145 lbs - and knee problems induced by regular width of today's crankset...

You can mount an XTR Octalink crankset on an Octalink ROAD BB (109.5 vs 112.5 for the XTR) to narrow the Q-factor slightly if your BB shell is 68mm instead of 73mm.

OR, you can opt for any square taper crank mounted on a 113mm-or-narrower (again, intended for a ROAD frame) spindle ... but, you have to certain that your crank arms will still clear the chainstays (which they may not) with the narrower Q-factor.

Similar situation with an ISIS crankset ... use a ROAD BB ... ... same caveat.

Some pedals have a narrower displacement from the pedal thread than others.

BTW. When ROAD & MTB cranks are mounted on the same BB on the same bike (at different times, of course), the ROAD crank's arms will usually be about 5mm more inboard (closer to the bike's centerline) on EACH SIDE.
