A club mate got caught in a crash on the weekend. The front rim on his Dura Ace c24 clinchers is toast but the hub is still good. I was going to look at building the hub (DA 9000) onto another wheel for him. He will be getting a replacement through the insurance of the rider at fault but may take some time.

I think it will be neigh on impossible to get another carbon laminate rim. What good options are there for a replacement rim with 16h? It is going to need to be something quite stiff with the very low spoke count. These will be a back up race/fast club ride wheel not every day use.

What are the best options for sourcing straight pull spokes, DT Aero comp? Probably better than the Aerolite with the low spoke count.

I'd abandon the effort and buy a whole wheel if you cannot find a replacement rim plus it wont be cheap. Maybe get an Ultegra or RS81 front wheel.

So many people have this dilemma: lovely smooth DA hubs with worn out or damaged rims. The C24 has been produced since 7900 came out IIRC - the user base must be pretty large. There must be a market for someone to produce a half - decent aluminium rim with the same ERD as the C24?

I looked into it once upon a time and gave up! Best option was rs81 c24 rim which were considerably cheaper than the DA equivalent

They are standard replacement parts from memory - LBS can confirm.

Doing a bit of research I found this. http://www.evanscycles.com/products/col ... m-ec028912. From a similar thread viewtopic.php?f=113&t=125415

Weight = 450g
ERD = 590mm

I am not sure of the shimano ERD but it seems to have a very similar profile. Although, As I will be replacing the spokes its not an issue.

The rim is quite cheap so might give this a go. What do people think about spokes. Will the DT Aerocomp give a bit of extra stiffness over the Aerolite?

I'd suggest the opposite. Find an open mold rim in 16h that you like and take that plus the hub to a builder. They can sort out the spoke details for you. For reference, I had a DA7900 16h hub built with a nice carbon hoop, and have somewhere around 20,000km on it now. Total cost was ~$300 all in.

I think a carbon hoop may be an option but a C24 is a alu track. A lot of alu rims will build up pretty flexy with 16h.

9000 series? Tubeless or Clincher hub? The clincher hub is easier to source spokes for. I'd put a 35mm+ carbon clincher rim on it.
