    Building a Lefty wheel (x-post)

    I've got a Mavic 717 disc rim and a new C'dale Omega hub. Has anybody recently built a similar wheel? What length spokes did you need? The calculator I use (http://www.damonrinard.com/) has an older Lefty hub and I think the dimensions have changed.

    I'm considering to build the same wheel (Mavic XC717 disc + Omega Lefty Hub).
    Did you finally get the correct hub dimensions?
    Which spoke lenght did you use?

    More than that.

    How are you guys getting the wheel true and dished?

    What is needed is the Cannondale Lefty adaptor that mounts the hub to a standard truing stand.

    Not sure about the spoke length thing.

    I rebuilt my front wheel with Wheelsmith double-butted spokes and aluminum nipples. The rim is an older Mavic 317 disk, which I'm told, was relabeled to 717 disk.

    The spoke length used was 256 mm on the disk side and 260 on the other. These are too short by about 2 to 4 mm per side (I see about 2mm of exposed threads on most of the spokes). I'm going to rebuild the wheel down the road with longer spokes. I'll try actually measuring the hub next time and putting the measurements into Spokcalc.xls and see how close my initial rough measurement was.

    Cannondale makes a truing plug that you can buy. Mines cost me $20. You remove the reverse-threaded cap holding the bolt in and put this plug in. This whole assembly drops into a truing stand (or front fork in my case) with a normal QR skewer and allows you to spin the wheel like a normal wheel.

    First go here
    http://www.dtswiss.com/spokescalc/we...px?language=en
    it's the best spoke calculator I've used.

    Then contact this person
    http://feedback.ebay.com/ws/eBayISAP...id=dirtychic25
    and purchase a set of lefty truing/dishing spacers. They are easier to use than
    the c-dale unit and much prettier. (not that pretty matters)

    Then build your rim and ride safely!!!!!
