I usually resort to doing a Lance imitation on a Tour de France spurt for a couple of hundred yards, but I get the feeling dogs are getting faster by the year
I used to have a frame pump under the TT which when raised aggressively made dogs cower, but my new one is under the DT :/
Never been sure if they really want to bite/kill/eat me when they're snapping at my furiously peddling heels... AirZound sounds interesting, especially taped to the drops (as in pic above).
