Just been reading BettySwollox sad thread about breakaway mudguard clips. Was surprised to notice last year that my otherwise well-sorted Nazca Fuego had none on the front. Fortunately I had a pair in my bits box, and set about fitting them. This was not so easy, as the left hand stays have been heavily reshaped from standard by Nazca and actually attach using one of the disc caliper bolts! This is ok for a hard metal loop (the bolt in question is extra long), but the plastic body of the breakaway clip would be too soft. I therefore drilled it out oversize and lined the hole with a metal sleeve to prevent compression ensuring a solid mounting for the caliper. I imagine quite a few bents have non-standard, modified front mudguard stays. Might be worth checking yours . . .
