Forgive me if this has already been covered. I tried searching and found similar results but I wasn't able to find a thread that completely settled my concerns.
I have a set of road bike 700x23c wheels and I would like to swap out the hubs for ones that can accept 6-bolt disc rotors.
Is it unwise to repurpose rims designed for use with cantilever brakes and use them on a disc brake setup? Is 28 spokes too few spokes for the front wheel of a disc brake setup? Should I choose larger diameter spokes when re-lacing wheels intended for use with disc brakes? I'm concerned about having some kind of wheel related failure and want to know if this is a bad idea.
The plan is to save only the rim (which is designed for standard cantilever brakes), then lace new spokes and hubs. The rear wheels are 32 spoke and the front are 28 spoke. I will have supervision and specialized equipment during the build through a local DIY bike service co-op.
This wheel build is part of a larger project: a disc brake retrofit on my road bike. Its part of an engineering project, otherwise I would just find a more practical and cost-effective way to do a disc swap. I use the bike exclusively for urban commuting around San Francisco (40 miles per week). Lots of hills, pot holes, and bad roads. The bike never gets jumped from curbs, never goes off road, and never sees rain.
Any guidance or direction would be greatly appreciated! thank you!
