Yeah, I finally tested the 2.0 tires last night and they were *identical* in CRR to the 1.0 tires, so no changes there.
Thanks for the info, but damn.. was hoping for an improvement. I heard 3rd hand of someone else getting the same result. Have you ever tested the Pista? Thinking that might be the best choice if you aren't doing tubeless anyway.
When you say 3W at 40kph vs GP5000, what is the weight?
A few answers for you and others:
-- I've never tested the Pista but heard it's a bit faster than the CS. I can't really imagine using one myself given the roads I race on so never bothered to get hold of one.
-- The watts saved is calculated at my weight, so 85kg for total system weight (on both wheels together)
-- On the TL version of the 5000, yes the main difference seems to be a thicker sidewall and bead, but that's simply eyeing it. I'm thinking of using them for races on bad roads and that have some dirt road sections.
-- On the regular Corsa (not Speed), I tested that too. The 2.0 is a bit better than the 1.0 but they're both dogs (IMO - sorry for people that like them). I actually kind of screwed that one up (the roller drum got dirty and I didn't notice at first) so would have to redo it to get it exactly right, but I'm confident in saying it costs another 5-7watts above the 5000TL (at 40kph for two tires and at 85kg).
