Hi guys, I wrecked the front rim of my DA7900 C24 wheelset. Instead of buying another DA rim from Shimano, I would like to re-lace the DA hubs to aftermarket wide rims. Pacenti, H PLus Son, etc.

My question is with the C24 hubs being 16 front and 20 rear, will I be able to build up a set of wheels stiff and durable enough as my everyday training wheels? I weigh 165lbs. Don't put down a ton of power but do ride on crappy roads and even gravel sometimes.

Those hubs need shimano spoke I think so it is a none starter. Also try finding a alloy 16H clincher. They do exist but no common either.

@grnrcr - Good luck finding a rim. There are a couple of fairly common options with 16h drilling like the KinLin XR300 and Velocity DeepV but they're quite narrow. AFAIK most of the new 'wide' rims only go down to 18h.

@bm0p700f - 7850/7900 series wheels use a regular straight pull spoke. 7800/7801 use the double ended spoke.

I think it would be damn near impossible to find a wide 16 hole rim. You could take a 32 hole and just use every other hole but the drilling offset wouldn't be correct at that point.

Can you weigh those hubs before you build? I have an estimate but never seen an exact weight. Also, can you weigh your rear rim? Thanks.

So if I use the XR300 rims, what are the chances of building up a set of wheels durable enough at 16/20?

I would email and ask Kirk Pacenti if he can make a SL32 with 16h. Sometimes manufacturers have a few undrilled rims lying around and can drill it on demand.

I just wrecked a WH7850-SL rear rim and the hubs are prefect (free hub is less than a year old thanks to a warranty issue). Does anyone know of a rim that could be used to build up a new rear ?

Cheers
Dave.

When my C24 rims go, I'm going to get some of the 38mm carbon clinchers from light bicycle. 380 grams of T700 carbon will be plenty stiff.
