and just to add some more work to our design schedules. SRAM have filed a patent for a similar sort of thing on the NDS with a axle mounted brake mount. There are the usual pros and cons and like the UDH is a puzzle at first. From what I can tell the frames ends are mirrored ie. same dimension inerface as UDH and that it uses current caliper and hub inerface dimensions. So no changes to components.
I’ve commented elsewhere this will have been driven by the big box carbon frame brands and it makes sense to them. Whether you adopt it for your bikes is entirely up to you, as the current interface works and will still work…until they decide to change the caliper mount standards. Which I don’t see for a little while yet.
Thoughts?
