Converting my 2011 Epic 29 EVO R from 1x10 to 2x10. I have read a bunch of posts here that have really helped figure this out. I've have decided to replace my SRAM 2200 BB30 with an XO BB30 from a friend and have the following questions:
1) Specialized stated the the Q-factor for this Epic is 166, Chainline is 49.5. I cannot find the Q-factor listed anywhere for the XO as an option, only the XX let's me choose between 166 and 156. Will this matter? Or can I go ahead and use the XO?
2) Is the XO BB30 crank likely to work with the SRAM-2200 BB cups or will I likely need to replace those?
3) From what I understand, even though I can find a compatible 2x spider for my 2200, I have been told by Specialized and SRAM that the chainline will be off and that this 2200 was built to a specific spec, just for this bike. Thus, I have to replace the crank. If anyone would like to weigh in on this, please do.
Again - I have read everything I could find on this site, really interested in answers to questions 1 & 2 as I have a viable (cheap) option to replace the entire crank.
