    Compact Crankset on 2003 Fuji Cross

    Hi All,

    I'm new the forum, so thanks in advance for any help and advice.

    I'm looking into putting a compact crank set on a 2003 Fuji Cross. I use the bike primarily on the road with 700x23 tires, and occasionally on crushed rock/dirt trails with the original 700x32 tires. In other words, I don't ride actual cylcocross, I just like the versatility of the bike.

    The setup the bike comes with is:
    • Crank set: Ritchey Pro Cross 48/38
    • BB: ISIS
    • 105 Shifters/Derailleurs
    • SRAM R-9, 9-speed cassette, 12/26


    I've so far only found two compact crank sets in my price range set up for ISIS. These are:
    • FSA Gossamer Compact ISIS Crankset 50/34
    • Leopard Cycles Carbon Crank set 50/34


    I don't care much about getting the higher gearing with the 50/12, although I would probably still use it on longer flats and downhills. I would be making the change to get the lower gearing with the 34 chain ring.

    I've been messing with bikes for 30+ years, but have never switched out a crank set. If I understand it, I just need to get the right tool to pull the ISIS cranks (Park CCP-4), switch out the cranks, then adjust the derailleurs. I'm assuming I'll need to shift the front derailleur a little bit on the seat tube.

    Does this all sound right or am I missing something? Other options I saw are a FSA Compact Cross at 46/36 but I'd like to get down to the 34. Or, go with a full new BB and different crank sets but then you're talking more money and I currently have no issues with how the bike rides, other than wanting some lower gearing.

    Thanks in advance.

    Can you just switch out the chainrings? I believe they're both 110BCD.
    Besides the crank puller, you'll need a BB tool. (edit: Oops, sorry - no need for this tool if you're keeping the ISIS BB).
    Yep, just the crank puller then.

    Thanks for the idea, SaddlBags. But I double-checked and the current cranks have a 130 BCD.

    However, the Ritchey website says the Pro Cross uses Octalink but the Fuji website says the bike has ISIS. Other Fuji bikes are also showing ISIS with Ritchey cranks. Is it possible these were made on order for Fuji?

    Is there someway to tell which BB by visual inspection?

    Thanks.
