    Truvativ chainring source

    Broke the bank and bought a bikesdirect Windsor for $300 and it has a Travativ Touro crank (aparently not even track specific) and despite my best googling, can't find anyone that sells Truvativ chainrings.

    Any ideas?

    You don't necssarly need Truvativ chainrings, just chainrings with the proper BCD (bolt circle diameter) to fit your crank.

    For example I have a 38T Truvativ ring on an LX crankset on my commuter. The only thing that matters is BCD. But if you really want Truvativ brand rings your LBS should be able to order them through QBP (Quality Bike Products, one of the big bike part wholesalers.)

    Thanks for the info. Would you know of a popular manufacturer that makes chainrings that would fit a Truvativ?

    What is the BCD of the crank? Without that you can't but the proper rings. But Shimano, Salsa, Sugino, etc, should make rings that fit.

    Why do you want to change the chainring? Wouldn't it be a lot easier and cheaper to change the rear cog if you want different gearing?

    Measure the BCD, then try Rocket rings or TA. I installed a Rocket ring on my Bianchi Pista with Truvativ Elita crankset. Rocket has the combination 110/130 BCD so it doesn't look very cool. TA has good looking rings made to fit 130 BCD but at more than twice the cost of the Rocket rings. Here's a link that will get you started on your search:

    130 BCD is your likely measurement for Truvativ

    TA Alize track rings appear to be available in 1/8 inch chain size only.

    The bike comes with a 48/16 which is 81in. 48/15 is 86.4in.

    I haven't ridden the track in decades, and my previous experience was pursuit, so it'l take me a while, but eventually I'm going to have to gear up, so I probably will need a 49 or 50 eventually.

    What do you recommend as far as gearing? I'm getting a 15 cog. Will 81 and 86.4 be ok to start? I eventually want to try sprints, no more pursuit for me. I'm going to start with the open track sessions at Brain Piccolo park.

    Stronglight, TA and Sugino will all make those sizes. The crank will be 130BCD I expect.
