Subject: RE: Do you use low Crr tires? I was reading through Tom A's blog, linked above, about tires at Crr versus Aero. There is really some interesting information. It is well worth a visit. A lot of the information is over my head but I still learned a lot.
He seems to say that the Vittoria only gives up 2.5 watts to the other, more aero, tires which is not much, but 2.5 watts is 2.5 watts.
Reading his blog also really emphasizes the amazing difference in rolling resistance between using butly versus latex tubes. I find it hard to believe but it is apparently true that latex tubes are just that much faster.
I run latex tubes in races but like others, have a butyl tube stashed under my seat in case of flat. The latex tubes are more dificult to install and I don't want to be fussing with trying to achieve perfection when trying to change out a tube in a race. |
