1996 on a then-knackered 1989 Raleigh Mustang on Panaracer Smokes 2.1’s that I had trimmed down the side knobs of the rear tyre to prevent frame rubbing due a slightly buckled rear rim!
We had to give up half-way around as my mate’s supermarket bike broke in a number of ways.
I’ve subsequently ridden it on all kinds.
On the subject of new bikes v old:
My 2007(?) Kona Dawg full susser on Mk1 coil Pikes is good fun on rocky stuff, but like a very heavy museum piece and less good on smaller stuff. Plush it is not.
It was best on a DHX 5 coil shock rather than the current RP23(?) air shock, but weighed even more….
My 2003 Kona Stuff (in singlespeed or geared guise) hardtail on Dual air Rebas is still a fairly light, great bike to ride.
