Octalink V1 or V2??

Just purchased a Ritchey compact crank that is Octalink BB compatible... I have a Shimano BB that is octalink but it doesn't seem to fit right. (It sort of fits, but there's not much engagement of the splines.. I've seen on Sheldon's site that there are 2 versions of Octalink.....I was tempted to bolt the thing together and see if it would work, but I'm afraid I may damage something - can anyone help?

Ritchey compact road is V1.....The V2 splines are longer and wider.If you honked it onto a V2 spindle,you've hosed it.

Bikes: '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

There are two Octalink crank/bottom bracket configurations. The road cranks (105, Ultegra, Dura Ace) used one bottom bracket type and the MTB (LX, XT, XTR) used a different one. They are not interchangable.

Whoops. Thanks for the correction. Yeah, I guess I knew the XTR used the same design as Dura Ace. I didn't know Sora and Tiagra used the MTB design. I always thought Tiagra was just a lower finish quality version of 105.
