Wait a minute…based on the Crr differences, that means the Rubino Pro Speed would need to be ~5W faster aerodynamically across the board in order to “out perform” it, on an overall system basis, no? Are you saying that’s the case?
Hi Tom,
Yes.
A couple things about the Rubino Pro Speed give me pause after looking at the BRR review. First, there’s no puncture strip and the tread is thin. Secondly, the scores for tread puncture resistance, and especially sidewall puncture resistance, are among the lowest he’s measured. If people think a Corsa Speed is “fragile”, then this is even more so…and it’s not even TLR. Thirdly, my past experiences with similar Vittoria models using that 220tpi nylon casing (Diamante Pro Light) tell me that these will probably suffer sidewall cuts just looking at them…just sayin’…
Yes, speed costs, how fast do you want to go? (j/k)
Actually, we’ve been riding the Rubino Pro Speed a lot and haven’t suffered the punctures we though we might. But the Rubino Pro (not the Speed version) has the same great low-drag shape, with more puncture protection. And of course other tires (like the GP4ksII or Corsa series) also fit the KNOT 64 wheels. And the rims are tubeless ready so you also have that option.
Well…according to Slowman, the GP4Ks don’t actually have “consistently great aero performance”…so, I’m not sure that’s saying much
LOL, “Show me the data” Ha ha.
Cheers,
Damon
