I found a couple nice Ritchey WCS compact cranksets to go with my P21 and NiTi.

They take Octalink V2 bottom brackets, so I'm trying to figure out what spindle length I should be looking for. I'm leaning towards 68x113mm, but I'm wondering if anyone here is running these cranks on a Ritchey like mine?

BTW, I'm running mine as 3x9-spd...

TIA!

I think you need to measure the existing chainline first to get a bench mark.

Should be 47.5 or 50mm.

Are there no specs for the cranks?
 
Unfortunately I can't find any information about these cranks. I believe they are early 2000-2004 perhaps, but I'm not even sure about that. For some reason my pic link isn't working right, but if you paste the link you can see what they look like.

My current setup is using an outboard bottom bracket XT m770 crankset, so that's a 50mm chainline.

The original ritchey logic bottom bracket was 68X120 square taper.

Hopefully my guess of 113mm is right because I just ordered a couple in that size! Doh.
