My favorite tyre.
Use 23’s and 25’s on my training bike.
Use them for my Audax bike so comfy.
Use them for cycling trips because they’re so reliable.
I ran out of race tyres for the last road race of the season, so I lobbed on some old 25c Rubinos and ended up contesting the sprint on them.
Needing tyres in a hurry I bought Gatorskins. Several tears after day one, puncture on day two. Too tough, uncomfortable and misbehave. Rubinos seem almost too good.
jonk mentioned the Fortezza Tri comps, a slightly snazzier version IMO, but they wear far far quicker.
Doing a 400km this Saturday on mine.
Edit; They’re always about £17 at Ribbles anyway. And I find them very easy to fit and remove by hand.
