plus one for the fender benders.
mate recently added a small piece of inner tube in a neogard type of stylee between teh front end of his crudcathcer and the seatpost tube, just below the seatpost clamp. Genius as it stopped alot of crap building up around the clamp/ i'd imagine that it would eb even more useful if you were thinking about teh seals on an uppy-downy seatpost too.
as we ride msotly cannock chase where there is very little in the way of claggy clingy mud, wheel pickup and clearance aren't much of an issue here, so in the back of my mind i have several designs for a crudcatcher "hugger" style rear mudguard. Anyone tried making one of these?
