I could make a prototype from a steel repair strip (like Mecanno) but wouldn't want to actually attach that to a carbon bike, I value my paintwork!įor now I've bodged it slightly using an Elite VIP ziptie bottle cage mount - see photo. Whilst you could do stuff like bracing/webbing it probably isn't necessary as it won't be taking any load, it's just to stop the unsupported end of the mudguard from flapping around. It could probably be as simple as a U-shaped bracket which attaches to a single bottle boss, goes around the seat tube on the non-drive side, and ends with a captive nut for the mudguard to screw into. I'll see if I can get some time over the Easter weekend.
