I’ve used 1.0 - 1.3” on my repurposed HT.
Geax Street runner I think was the 1.0”
Got rid of those for two reasons:
1) they were a wickedly, tool-breaking tight fit. A roadside tube replacement with cold fingers was a gamble.
2) 1” on a bike with a pannier wasn’t a great combination when dealing with curbs.
I had some Hutchinson Top Slick, which I really liked for unloaded riding. But again, they weren’t fully pannier-compatible.
Mostly, I’ve run Conti Sport Contact in 1.1-1.3”.
These will play nice with a pannier bike, service-friendly and good enough in grip and rolling resistance for me not to think about it while JRA.
