12H Hub Used by a Guy Weighing 83kg

Posted on
  • I weigh 83kg and got a 12H Mid Flange Royce Front Hub and planned on building it up. I am a bit worried about using the wheel on the road (which was my intended use) so what do you guys think? I called up Condor and they said I was mad but I keep getting different opinions.

    Many thanks.

  • You’ll need a seriously strong rim and some seriously strong spokes under a lot of tension. At least it’s a good hub. The hardest part will be finding a 12 hole rim. The only ones I’m aware of are tubular Shamals.

    You could always phone Cliff at Royce up and ask if he can drill 12 more holes in it.

  • add 12 more holes

  • Add 24 more holes you fatso

  • Called them up and they said that they can't add any more holes, I guess I have to sell the hub sadly...

  • 12 hole hub?! Bonkers

  • Any decent machine shop can add the additional holes.

  • Any shop that you would advise senor bear?

  • Pass. Although 20 mins on the phone should find you one no probs.

    There's a 12 spoke Corima front wheel with carbon rim hanging in our basement. I've only seen my house mate use it twice in 4 years and even at ~60kg's he's rather cautious with it. I'd not even consider sitting on his bike with it fitted at my size.

    Pretty much this. Lightweight makes a mind-boggling 8-spoked front wheel and that thing is significantly heavier than pretty much everything else they make, front or back, because of the massively strong rim, spoke and hub. So you probably won't be saving any weight there.

    The hardest part will be finding a 12 hole rim.

    That said, no one said you have to use all of the holes on a rims: with a suitably strong (and I mean extremely strong) 36-holed rim, you can THEORETICALLY use every third hole. Any other number of holes on the rim will THEORETICALLY work too, but the then the spokes will not be evenly spaced and calculating spoke length becomes a nightmare, see http://sheldonbrown.com/mismatch/index.htm for example. And a 12-spoked wheel is going to be a real bitch and a half to true as well.

    All of this is IN THEORY ONLY, I'm not saying you should actually do it.

    I assume you bought the thing from sasoph? Why not ask him how he used it?

    I've seen it done to a Hope hub by a friend of a friend. Masking tape, plenty of measurements and two drill bits.
