I have a Bianchi Via Nirone 7 which has a full 105 groupset apart from the cheap looking FSA omega chainset. I would like to replace this with a compact 105 item but am not sure how to tell if it will fit, could you please let me know how to check this?

Many thanks

    It uses a square taper bottom bracket so you need to be sure you get the correct bb/adapter.

  • Thanks. So I can buy an adaptor rather than having to buy a shimano BB.

    A Shimano 105 BB will only cost you about £20 and they're a doddle to install, add that to your chainset and your looking at £120ish.
  • Thanks. I think I'll do it that way.
