I am a fender newbie. i mounted my berthoud fenders for my fall/winter commute. But something seems very wrong. the rear fender is not keeping spray away from my drivetrain, or left foot for that matter. The fender atttaches to the chainstay bridge with a p-clamp in the upward position. The fenders are 40mm wide, tires are 32mm Vittoria Randonneur. I've got a bit of clearence and the front fender sits and works perfectly. i guess i could go down to 28mm tires - but i'd rather have the extra cushion. i am also going to reverse the pl-clamp with the intention of lowering the fender. any other suggestions?
aren't fenders supposed to keep that gunk off my bike?
