Too cheap to use a jet-wash on my bikes. Hose and Muc-Off all the way.
Out for 2.5 hours on the 29'er today. No big revelations, I'm not that smart of a rider, but I think it does maintain momentum a little bit better - definitely noticeable on a couple of road stretches I did, where I came over all Tour de Falkirk for a few hundred yards.
Thaw seems to be under way, plenty of mud and oomsk, still some hardcore ice hanging about though, and not all of it the slushy kind either. Only one low speed off due to the ice, got off the beaten trail up Callendar Park and found a couple of nice little bits through the trees - no tyre tracks either... Let's offroad!
