Emo 149 Report post Posted December 4, 2018 Can anyone give some advice or links to reviews on 25 mm v 28 mm? I have been using 25 mm for some time and are great, love to read or hear more about the newer 28 mm. Share this post Link to post Share on other sites
goughy 3,185 Report post Posted December 4, 2018 Only experience I have is a mate rides them now, and swears by them. Reckons he's no slower on them but the ride feels so cushy by comparison. Pretty sure he said he rides the same psi in them as he did his 25's. Share this post Link to post Share on other sites
more 156 Report post Posted December 4, 2018 I have NFI but from Zipp "23mm tire – optimal for TT/tri25mm tire – almost as good, especially in rear. Using in front will increase drag and worsen crosswind handling characteristics on our narrow/deep rims28mm tire – tangibly worse aero performance, especially for drag and handling in crosswinds" Share this post Link to post Share on other sites
