I agree about traction in the wet. I find I have to climb seated a bit more than I used to with the old Rubinos
Rubino Pro III "150 TPI" 28mm review:
Bought in 2022 (I think due to a thread I can't find by vickster?)
Mostly very happy with them (9 days in NED/GER/BEL 👌but wet!), especially at the price.
Today uncovered the Achilles Heel: grip :-(
Now I think today's conditions were very tricky (3'c, roads not QUITE dried out after prolonged rain/flooding, etc ... ) But I had several moments.
GP5000 on the front coped fine. They do cost twice as much! Tyre has done a few 1000km, so worn in, but lots of tread visible so I wouldn't expect Worn Out.
Not dreadful though - think Gators would have been even worse.
So: totally unscientific data, but enough to convince me. For now. Might put a more premium tyre on until April ...
