  • I've got new wheels coming in the next few weeks and highly tempted by the 26mm Turbo Cottons. However, In 7,000 km I've not yet had a puncture with 25mm GP4000IIs and have gotten complacent enough to leave my tools/gas at home lately.

    Considering above comments about Durability am I to be sorely disappointed?

    My old wheels are 11mm wide internally requiring a good 110+ PSI for effective use, is high pressure having a positive effect on my durability?
    New wheels are a lot wider allowing for lower pressures and hopefully a bit more comfort.

  • The 26mm cotton have the same rubber width as the 24mm cotton, the only difference is more sidewall on the 26mm.

    In theory 26mm are more likely to get cut on sidewall.

  • Very useful information, thanks ed.
    i guess the comfort difference between 24/26 is non existent

  • You sure the rubber width is the same? The 26 would look a bit funny with less rubber, no?

    I think I have both at home. Don't make me get the ruler out.
