My last thorn was similar to another thorn a couple of miles from home and...................I put 100 strokes into the pump and made about a quarter a mile then I put 150 strokes in and made a little more then I walked
Deeper tread is the answer with very wide grooves like a cheap and nasty MTB nylon yoo fart, like I use on the other trainer that I have not rode for a month cause the conti shod trainer is way faster
not fast enough for granddad on a stealth pedelec
