I'm looking for some guidance on how to determine if a certain disc brake is compatible with a certain cyclocross frame.
Specifically, here is my particular situation. I have an extra set of Spyre TRP brakes (and wheel set with matching rotors). I'm looking to get a carbon frame direct from a Chinese manufacturer and build a bike, preferably from Dengfu since they seem to have a very good reputation and have been around for quite a while now.
Originally I was interested in the FM286:
But that frame is not available in the size I would need until another production run can be produced, which will be about a 3 month wait. Dengfu does have their older cyclocross frame available in the size I'm looking for, the FM059:
I'm really not concerned with the 50 gram weight difference, but I would prefer the FM286 due to the newer style front derailleur mount.
Anyhow, my question is how universal is the compatibility of disc brakes to frames? Would the Spyre TRP Cs fit both frames in the front and the rear? I notice with the older style frame (the FM059) the rear caliper mount is on the bottom of the seat stay, but on the newer frame (the FM286) the rear caliper mounts are towards the rear of the chain stay. Does this matter as far as rear caliper compatibility? Please advise, thanks!
