Clem chain/fender interference

[Jim Bronson]

One of my big regrets of my Clem is not paying Riv the $40 or $50 they wanted to install the fenders.  Instead, they just arrived in the box.  After a particularly cold rainy ride a couple of years ago, I finally installed them.

Now it seems I cannot adjust out the tendency of the chain to rub the fender.  They've always rubbed when I use the 34 in the back and the next lowest gear as well.  After the bike's only trip ever to the shop this month to diagnose a dragging freehub which has since been replaced, the chain is rubbing worse than ever in the lower gears, and the front small ring is about impossible.

I'm feeling like I want to take my Dremel to the fender and trim back a quarter inch or so.

How does Riv install these fenders?  Surely they don't send them out with this kind of interference.

From the Riv website for SKS fenders:

Most of the time these fenders fit without modification, but sometimes the fit is imperfect and they need home-surgery to clear a front derailer or chainstay or seatstay. Use side-cutters or snips of some sort to cut away the interferering plastic, then dremel or hand file the rough edge smooth. Add tough tape to cover it or leave it raw.

+1. It's not hard to do. In fact, some wide Planet Bike and SKS fenders come pre-cut.

I used a milling bit in a dremel tool.  This is the best pic I can find, but hopefully helps.  Just took a moment, didn't affect rigidity/integrity of fender at all, and was able to locate it precisely as needed.

I had this issue on my Clem. I used a pocket knife to make the notch. It took two minutes.

I had this same fender chain rub issue, and had a bike shop cut out that little section of fender pretty much the same as Keith's photo. Still plenty of coverage and no noise :)

Ok, so it sounds like my instinct to use the Dremel to trim it back is what everyone else is doing.

Thanks.
