Is it possable to keep my Sora Front Crank when I upgrade my shifters to 105's?
I have just made a silly bit on a new set if shifters on Ebay and won them :shock: Will i have to upgrade the crank too? Think ill have to change the Font and rear derailer?
Thanks.

    It'll be fine. If your Sora stuff is nine speed anyway it'll all just work.

    If they are the black 105 sti's from Nottingham at £101 you beat me by £2
    Yellow is the new Black.
  • Ha ha yeah the were, sorry! I put the bid on this morning not expecting to win them.

    If your Sora stuff is 8sp or 9sp it'll just work.

    If you run 8sp chainset with 9sp chain you'd not have any issue of 8sp rings being so thick that a 9sp chain was too narrow to fit on them, nor the gap between being so wide that the chain fell down between.

    OP says will need to replace front & rear mechs - no you won't, they'll happily work too.
