I'm wanting to build up a road race wheelset using some Mavic CXP-30 rims that I've had for years. They're in really good shape as I only rode them on the bike I got them with for a couple of years before I replaced them with something else, and I wasn't exactly putting a ton of miles on in that period of time either. The front is a 24 hole rim, though, which makes it interesting. I've found 28 hole hubs that will work on the rear wheel, but finding high end 24 hole is tough. DT doesn't offer the 240s that way, King classic hubs have the same deal. I'd prefer Campy compatable, but I've got an adaptor cassette so Shimano stuff's alright. I'm going for weight savings with the hubs, so I'd like to stick with the really-light crowd (like the DT 240s). Any suggestions?

If you want weight savings try another 30mm rim. Those puppies are 100 grams heavier *each* than the newest 30mm rims out there.

If you are trying to rebuild these on a budget consider mixing hub brands. Lots out there in 24 spoke front.

I was checking out Velocity's Deep V and while it's a bit lighter, it's not that much better. Suppose I should be rim shopping as well, as the whole hole issue seems to be a bit of a deal breaker.

IRD, speedcific both make a 455 gram 30mm rim. Reynolds and Easton also use a 30mm 455 gram rims on their Alta and Ascent wheelsets respectively.

Check out Sun-Ringle. The City Flea hubs are pretty light (75g front, 190g rear), and the front comes in 24-hole. You can get the rear with a Campy carrier.

When I was building a fixie I was going to have an existing rim rebuilt and the LBS indicated that it is very hard to reuse older rims (these were 15 years old). The story was that the tension holds them in true and when you remove that frequently they are not very true any longer and very difficult to get true. They said it could take longer in labor than it would be worth.

I don't know if I was sold a story or not. I didn't buy anything from then so they didn't get any business out of it.

These rims are definitely worth using it sounds like, but I don't know if I'd want to throw $$$ hubs at them.

I'd be building them up, so the only money I'm out is parts. But it's a valid point, chef.

I might just rebuild them with new spokes and replace the straight gauge spokes that are on them with something more aero in nature. The hubs are high quality (DA 9 speed, hence the Campy cassette for Shimano freehubs) and are still in great shape.

Given that this is primarily a project to give me something to mess with on the bike, it's not that big of a deal. Build these up with new spokes, play with them a little and keep them as a backup set. Sounds cheaper and about as entertaining as the first idea.

The Campy freehub is not a bad idea though.

Which conversion cassette were you using? How did it shift?

I'd definitely use butted spokes instead of straight guage.

I have SpeedCific hubs on my custom made wheelset from www.oddsandendos.com, its great. Mike Garcia at oddsandendos also sells a 51 gram Soul-Kozak 24 spoke front hub as well as some other brands.

white industry makes 24 hole hubs I believe
