I reckon they are all do-able. Plus, it will mean you have less time hanging around in cold wet clothes when you re-group mid ride. Let the geared riders ride off up or down the hills, and then they can freeze/dissolve whilst stopped and waiting for you. Win!
Ah, that could be significant then. The rim strips that are in there are just like normal rim strips and are a green/blue colour. Definitely nothing built up at the valve area.
Looks like I need to get some specific rim strips then.
