    Fuji Gran Fondo 2.5 Crankset Question

    Greetings all. This is my first post. I am considering a new road bike in the spring and am leaning towards a couple of carbon frames. Scott CR1 20, Trek Domane 4.3 and, the only one I have ridden so far and really like, the Fuji Gran Fondo 2.5. The Fuji is the only one of thee three without a triple chainring option. I have old knees and live in hill country so I really want a triple.

    My question: Will the Gran Fondo accept a triple crank and will I need a different front deraullieur? The LBS has offered to make the swap if it;s doable but the guy I spoke to didn't have the tech savvy toknow one way or the other if it will work.

    It will, but it's not cost effective. You'll need a new shifter (left) and front & rear derailleurs, and possibly chain if it was sized properly for the compact.
    A more affordable route would be to swap in an MTB rear derailleur and cassette, you'll still probably need a new chain as well. Much easier and much less expensive.

    Thanks for answering so quickly. Why would the rear derailleur need replacing? I would keep the stock 12-30 cassette. Also, even though we didn't go into a lot of detail, it was the saleman who offered the swap. He seemed to offer it as an incentive.

    Google "rear derailleur capacity"

    This thread is pretty good...I know it's from MTBR, but the info still applies to road bikes.
    When to use a Long Cage vs Short Cage Derailleur?

    What he said. To get gearing equivalent to a triple with just a cassette swap you will probably exceed the capacity of the stock derailleur. An mtb derailleur will work without issue. I was thinking an 11-34 or 11-36. A new road derailleur in a GS model should handle up to 32t in the rear, and 'may' handle 34. 36 would be pushing it and shifting would likely suffer.
