Excuse my ignorance on the subject but I'm looking to replace the SRAM force chainset on my Boardman with a compact and I can't seem to find a compact BB30 item.

Any suggestions? (I'm assuming I can't just fit smaller rings to mine to make it more sportive friendly?)

    Oops, my bad. :roll: Thanks for that anyway dude, I just presumed that because wiggle didn't list it then it didn't exist. :)

    I'm guessing my assumption that I can't fit a smaller ring is correct? Different sized spider no doubt. :?

    The specs here show that the 2010 Pro Carbon comes with BB30.

    Compact tend to be 110mm bcd spiders. I think you might be able to get a 50/38 on the standard 130bcd that you have by changing the rings. Don't think you can go lower than the 38 inner though.

    Sram Red is also available in BB30 compact

    compact = 110mm BCD = smallest ring is 33t

    std double = 130mm BCD = smallest is 38t (39 for Campag)

    They do indeed, SRAM force carbon cranks and BB30. 8) You'd be amazed how good a Boardman is!
