Lots of mudguards are available for mountain bikes but these days when most riders have or aspire to have a dropper seat post a lot of the designs just don't work as they attach around the post with a big clamp that would hinder the dropping function. So i needed to look for something that fitted in a different way and I came across The Mudhugger
guard fits again with zipties to the fork legs and arch (or in my case
the crown of my rigid forks) and goes a long way to stopping the mud
that is thrown forward from the tyre and back into your face.
guards can be fitted with "extenders" if you feel there isn't enough
coverage. I found them both fine as standard. These aren't like road
bike guards though, so if you are expecting to get no mud on you at all
then you'll be disappointed as of course they only cover half the wheel,
and mud will find its way onto the seat tube of your bike, BUT having
a dry backside is so much preferable and comfortable than muddy legs,
there is nothing worse than riding for hours with wet shorts!
proof though is in the pudding though and after a two hour ride in the
tail end of hurricane Bertha my shorts looked like this
