MRP on a 97 Animal

[ianc]

Hi - I'm looking to fit an MRP World Cup system 1 on a 97 Proflex animal, and wondered if people could help me with BB size? It's an octalink XT crank and BB, I bought the cranks/BB/MRP secondhand together. The BB that came with them is a 73x118. I *think* the animal needs a 68 shell BB, so is it as simple as getting a 68x118 ES-71 XT BB?

Cheers,

Ian

I've had nothing to do with MRP's but I would of thought that if you purchased a new one you wouldn't be expected to fit a new B/B,so I'd say you need a standard size B/B to go with your MRP,I'm unsure what size B/B you would require with an Octalink system but the standard square taper that came on my old 856 (world cup frame) was 68x108mm.
Hope this hasn't confused matters

Just had a look at some MRP's and there can be the possibility that a longer spindle could be required, if only they gave the extra length required over the standard spindle,but yes you are running a 68mm shell so will require a new B/B.

Guess I'll just bite the bullet and hope it fits, MRP haven't got there instructions on the web yet!

Thanks for looking Simon,
