QNT, mounting a 1" curb at 45 degrees, about 10mph. Rear tyre slid, then gripped, equivalent of a motor cycle high side. Blink of an eye, you would have missed it. Ended up side down, flag, head and hands on pavement. Potentially embarrassing. No damage.
Taken by surprise. Have done the same move many times before, no problem. Different rear tyre this time. Marathons. Hard. Don't like them; let go and regrip digitally, on off. No warning, unlike marathon racers. (Any news on the Shwalbe trike tyres?)
Learned to mount even shallow kerbs at a more acute angle.
I have front suspension. Much harder to lift the inside wheel, since fitting. Sometimes outside slides, rather than inside lifts. (Could be desirable to have a tyre that gently lets go just before the inside lifts!)
3 wheeled recumbent, so good in this weather!
