Surly Cross Check Chainset and stuff....
After much reading, forum scouring, etc etc I've decided to buy a Crosscheck. I really want it for road at the moment but hope to do some cross next year. I've sort of decided on 700 wheels and Ultegra STIs so mostly I'm set - except for the BB and chainset........
I've seen that most of the racers tend towards 39/48 but if I go for a double (don't think I want a triple) road chainset I can only get down to a 52 on the big ring. Does anyone have an opinion on this? Is there a double alternative that will shift with the Ultegra STIs and get me the flexibility of a 48 or bigger ring?
Also for the Crosscheck I have assumed I need an XT BB to fit both the frame and the Ultegra chainset. Any idea if this is correct? Wil the chain line up etc etc
So I guess I 'm really asking the following question. What BB chainset, front derailleur and shifter would I need on a Crosscheck to get a double set up with 39/48 up to 39/52 (if at all possible?) considering I would like the STI shifters.... Phew.
