    If you look around (I'm assuming you have a "compact" double with 110mm BCD) you will find that FAS do 39 and 52 tooth chainrings to suit. Here is one example - they're called Pro Compact rings.

    I assume that you have a compact double chainset, and you want larger chainrings?

    If so, you need some 110 BCD chainrings to fit your chainset.

    Praxis works are a company that make larger ratio rings in this BCD. They aren't cheap, but they are excellent.
    Red bikes are the fastest.
  • For alternate chainring options you need to find 110 BCD rings in the sizes you want. I personally run 50 outer and 36 inner.

    A supplier with a wide range of chainrings is spa cycles. For example £10 for an inner stronglight ring:

    £14 for an outer ring:
    http://www.spacycles.co.uk/products.php ... b0s149p293

    The outer rings do have pins to help shifting.
  • Why do you want to change to a standard chainset and why do you think it is an upgrade?
  • Doesn't really matter why he used the word upgrade, or why he wants to change gearing. The question was what rings to buy that would fit.

    I'm using Sram red 52/38 rings on my 110bcd chainset. Spa cycles is a good shout on somewhere to buy rings though.

    I think the OP doesn't understand what standard and compact cranks are. That would explain his thinking that either / or was somehow an "upgrade".
