    Surly track hub dimensions?

    I am getting ready to build a wheelset for a fixed gear road bike, my first wheel set. I was planning on using Surly's track hub for the rear, but I am having some trouble determining the proper spoke length. I've gone to the DT Swiss site and used their spoke length calculator. The calculator only lists the Surly 1x1 135mm rear hub, but not the 120mm track hub. Surly's website wasn't much help either. The hub bodies look very similar, are both 32 hole, and high flange. The only difference that I can see are hub the threads. Does anyone happen know if these two hubs are similar enough to use the same spoke length?

    I don't think you would be able to use the same spokes for a 135mm hub as a 120mm hub, since it would likely throw off the dishing.. (or the spoke would be poking into the rim tape?)

    you might want to e-mail surly and see what they say, otherwise you could take it to a LBS...

    I am guessing that the hub bodies are the same and only axle lengths are different. So building a wheel will take the same size spokes regardless of axle length.

    For a rear track wheel there should be no dish. Both sides should be the same spoke length (the DT spoke calc confirms this). The hub will sit in the middle of the drop outs regardless of axle length (as long as it is spaced equally on both sides). This enables you to flip/flop the wheel.
