We just bought our son he's first MTB and I haven't hit a trail for like 8 yrs, so not up to speed with all the new bits n pieces. Anywhoo, I want to put a mudguard on my son's bike but he has a Manitou fork with the arch on da back. Just wondering people's experiences of putting a mudguard on one of these? Do you just put it on the same, run it backwards, etc etc. The wheels are 24 in. Thanks.
