I fitted my Trek 7100 with SKS mudguards not so long ago, and they’ve been fine ever since, if just a little ill fitting.
I noticed this morning that the back of the front mudguard was rubbing ever so slightly against the tyre. A little manipulation of the mudguard solved the problem. It was only when I got to work that a fellow cyclist mentioned to me that my front mudguard didn’t look exactly right. Looking at it closely I know what he means.
I have about 1.5” of clearance at the front of the mudguard and about 2mm of clearance at the back, where it was touching the tyre. The front mudguard doesn’t follow the circle of the wheel at all. There is a fixed bracket on the top of the mudguard that attaches to an eyelet on the frame, under the brakes, I’m guessing this is what dictates how the guard ‘sits’ around the wheel – so why is it so far out?
It looks a bit funny I must admit, and the clearance shouldn’t be so different back to front, should it?
