This Xero rim is brand new but has 20 spoke holes around the rim with each pair being in parallel. So you end up with 10 pairs of 2. We don't have any hubs like that in our shop and I have never seen one like that.

What the heck kind of hub is used with that kind of rim? How do we figure out spoke length? Does anyone even have a hub like that laying around that they would like to donate to our co-op?

It's a Formula (Taiwan) hub and Xero is their wheel brand.

I have a front hub if you need it - but not the matching rear.

Well since its a 20 spoke, I figure its only a front rim. We only have 1 of them anyway. Do you know the spoke lengths by any chance? If you don't want it, we could put it to good use.

Radial pattern spoke length is pretty easy to figure out, using a couple of longer ones.

Sure I can send the hub to you...PM me.

However, be aware that the rims with parallel spoke holes are going to crack...these things are kinda phasing themselves out in my part of town...

You can however re-use these hubs on regular rims. One member only a few months backed laced a front radial to a traditional rim. Looked a little skewed but it works.

You can lace drive rear like normal - standard 2-cross...and then on non-drive probably do a half-and-half +1mm / -1mm spoke length compensation for the skew that results....or something like that.
