    42T - 110 BCD chainring recommendations?

    Thanks for entertaining my build questions, I appreciate the advice - and I am almost done!

    I want to run 34/42 gears, so i have decided to ditch my standard 130 BCD Shimano cranks and get the the FSA Gossamer Compact MegaExo 50/34 Crankset (similar to this
    http://www.pricepoint.com/detail/227...4-Crankset.htm

    It uses 110 BCD rings. I have replaced the small ring with a SRAM Red 34t chainring and am looking for a good 42T 110 BCD chainring. Any recommendations that would beat just using my big 42/110 BCD ring from a Shimano MTB crank (other than weight since it is steel)?

    isnt the mtb ring 4 bolt?
    if its a steel ring isnt it sort of funny to pair that with the expense of a sram red ring?

    42 should be easy enough to find, or go 44t.

    just spend the $ as you'll probably use it for a long time and clunky shifting is not cool.

    Since you are using 8 speed and can custom build a cassette to your liking I'd find a 44 front ring. There are some dry/concrete sections to some courses that a 44 could be useful. Also, over really bumpy stuff a low cadence can help smooth stuff out.
    I'm not one for fawning over bicycles, but I do believe that our bikes communicate with us, and what this bike is saying is, "You're an idiot." BikeSnobNYC

    Thanks again - I will go with a 44 per your suggestion - and yes, I have already arranged a "custom" rear cassette 11-32
