Always thought rear guards look crap.
Where I'm riding lately there seems to be lots of large stones flicking up and chipping my paint.
Is there a rear guard that looks good?
Have a Crud Race Guard, similar to the above but fixes to the seatpost. Quite good. VGC. The rubber shims are long gone but easy to replace. £7.00 posted if you are interested....
If you're worried about chips maybe some helitape is needed. A seat post mounted guard will be no use .However I've used a Zefal No Mud and placed it well back of where it should be. That would work and then the Crud guard keeps the muck off my back.
