I’m happy that’s concise enough as far as testing goes.
I could stick on the other Kenda tyre i recently bought, but the testing shows me that even with GP4000s, the Isaac is a chunk lower HR for me. So fitting a tyre in the middle of the two is still pointless, the Isaac is quickest/best/whatever.
A pleasing one is that i was the same on SPD-SLs and Flats, that helps as i wonder if part of my knee issue i sometimes get on the Isaac is down to SPD-SLs, so i can run flats now on it and know i’m pretty much exactly the same.
Unlikely to race now and will just call it an easy/gentle/recovery spin day 🙂
