Just had a rim failure (Pacenti), and need to get the wheel built up with a new rim and spokes. It's a slightly tricky hub (24h Powertap GS) with straight pull spokes and effective flange width that's really a bit too narrow. Hence the high tension and a spoke ending up pulling through...
So I need someone good (otherwise I'd just do it myself). Happy to post, anyone got any good recommendations?
Thanks!
DCR and the Cycle Clinic have both been good for me.
Cycle Fast in Halifax, excellent wheel builders and not too £ 😃
Rim swap should be fine.
I'd just drill a new spoke hole myself.
Where are you based?
Pacenti rims dont like high tension in my experience.
DT Swiss RR 411 asymmetric could be worth a look, the offset spoke holes helps with spoke tension side-side, PHR washers help spread the load inside the rim.
Max weight on RR 411 is 110kg, RR 511 is 130kg if you want something a bit stronger.
I think the previous post from bigyan is on the money. You don't have a wheel builder issue, you have a rim issue. I'd have a discussion with a couple of builders and see what rim they recommend. Probably, as bigyan said, an asymmetric rim with a robust spoke bed and maybe nipple washers too.
Used DCR for both road and MTB. Good advice from owner. Excellent builds with good tight spokes.
It's worth building with an offset rim like a Kinlin XR22RT. Drop me a line at pete@owenwheels.com
What is the mm offset on road rims?
The asymmetric rims are offset by 2 or 3mm. The flange offset varies depending on the hub.
Thanks guys!
The effective flange spacing / positioning is such that the rim sits centred over the flanges, i.e. you use the same length spokes on the DS and NDS. I didn't realise this when I bought the hub, otherwise I might have gone for a G3 instead of the GS... So an asymmetric rim is no good here.
(I did use nipple washers on the Pacenti, but clearly there's only so much they can achieve.)
I'm based in Oxford (often work in West London though).
