Wheels, rolling resistance - anything new?

Dawn Cass

Pulling on the team for anything new in the world of rolling resistance and tires.  I have seen the posts and the chart that I believe Rich posted before and the conclusion has been Vittoria open corsa has been the best.  I have been racing on them and pleased but now time to get a new set.  Just wonder if going with the same is the best choice or if there is new data out there to suggest something else.  Not sure if the open corsa cx still exist or there is an updated model.  Thoughts?

Conti gt 4000 (apparently) is the best 25 mm tyre. You need latex tubes to maximise the benefit.

A very interesting podcast I listened to last year.  Wider tires, lower pressure seems to be a better choice than narrow high-pressure tires.  I've lowered my pressure based upon this talk!

I'm looking at the Conti TT, again, from a popular test site that's out there.. 25s for sure

@Peter Greagg I have always run 23c...if I go to a 25, does the wheel need to be adjusted? Thought I read something to that effect however to be honest all I have ridden was 23 so haven't thought about it.

i just bought a Vitoria 25 and was about to take it back....but all my other wheels are conti 4000. Will need to check difference to the TT.

thanks all!
