  • the hub shell is more than stiff enough in torsion to make wind up a non-issue.

    I was always taught that tangential spokes are a must on the drive side, but I suppose the above mitigates that.

  • And of course the Powertap hubs "have to" be tangential on the apparently non drive side... .. the left side of the hub is driven by the torque tube straight off the freehub body.

  • It improves tension balance by a couple of %. Regardless of what mavic claim the torsional stiffness of the wheel is reduced. They have 5 spokes instead of 10 on there wheels doing the drive. If mavic just increased the spoke nipple bed thickness a bit on there rims they would not have to worry about the tension balance so much.

    Worse is zipp with radial drive side and 1x NDS or is it the other way around anyway thats proper daft.

    This is the problem with designing wheels to hit a mass goal. It forces all sorts of design tricks which compromises the whole wheel.

  • Great deal on Alpine III

  • That sounds pretty close to the build I'm looking at. Did you source all the parts or did @arup do it all? And how much did it all come to in the end?

  • I sourced it all, but worth noting that now Arup has everything needed to cut spokes, so in future I’ll ask him to sort that.

    Cost was a shade over £400 all in.

    Worth noting that the hubs are lovely, but pricey. You can easily save £100 or so going Miche

  • Does anyone know how much of a difference the ‘angled drilling’ on the Ryde Andra 40 makes when building up Rohloff wheels? the rims I’ve found~ in stock ~are standard drilling.

  • I've just (about 2 weeks ago) built a pair of Andra 40 in 20"(406), all the nipples look nicely lined up with their spokes.

  • so you can buy standard Andra 40rims, which are pretty easy to find.. and Andra 40 with angled drilling specifically for Rohloff hubs. Just wondering if the difference is significant enough to do a bit more hunting around for the rohloff ones 🤔

    Was the rear you built up a rohloff speedhub? Would the difference be more or less significant if I’m using a 26” rim..?

  • Also I've bought a couple of 32h hubs instead of 36h by accident. How much will it compromise the strength of the wheel by using 4 less spokes? Rohloff hubs, Ryde Andra 40 rims.. to be used on cargo bikes.

  • How much will it compromise the strength of the wheel by using 4 less spokes?

    1/9 🙂

  • hmm think I'll return them for 36h hubs..

    Although do have an issue with the 36h rims cracking along the inner well bed.. wonder if having less holes could make them more resistant to that 🤔: )
