My experience is that if there’s water and mud on the ground, a fender doesn’t help much. Especially on a higher travel mountain bike (I ride 150mm of travel front and back) where you can’t get it close enough to the tire. After a while it turns into a gunked up rattling sagging mess. I’ve tried a few and ultimately stopped trying, even on an XC bike. I don’t meet people using them either.
