I have an Orbea Diem w/ disc brake and rear rack mount. Will the SKS Raceblade Fender fit on it?
Of you are using a tire less than 23mm they should fit fine. I think the Diem has a larger tire though. Also, I believe the Diem has mount for standard fender so if you are looking for a full time fender get those for sure because the raceblades are best used one day at a time and not permanently.
