I’m not that concerned about them TBH, they do look **** but then so does riding a bike to most people, seems an odd thing for people to evangelize about though…
I use/have used crud catchers, old bits of inner-tube between fork crowns or a DIY version of a “Mucky Nutz” type fender on the front end of various MTBs to keep shite out of my eyes but I can’t say I’ve ever been impressed enough with any rear fender/mudguard to actually want to fit one to any MTB that I own…
Road bike – close fitting guards in winter makes perfect sense to me, but I don’t have any at the minute so I cycled in today without, and as there was almost no standing water and I didn’t die or get particularly wet… I doubt I’ll be able to get away with that for much longer so some new road guards shall be ordered tonight need to decide between something from SKS or Crud race guards…
