Better p protection?
12% better rolling resistance 20% better puncture protection 10 g lighter (25-622) than the GP 4000 S II
Aerocoach have confirmed the rolling resistance is better (not sure if it's 12%) the rest is un tested. I've bought a pair to try them out.
Ah I guess I’ll have to try them. We should really pool our testing expenditure over the next few months!
Have you tried the 46/34 yet?
