Hello,
I have a Colnago C60 currently running Mavic Kyserium SL's & Conti GP4000S / 25C.
I have experienced a bit of rubbing where top of tire meets frame arch.

I have a set of Zipp 404's arriving and I'm wondering if anyone has any experience with this combo.
C60/Zipp's/Conti 25C
I'm hoping that the the wider rim will lower the tire profile enough.

any advice based on experience appreciated
thx
Greg

    What width are the Mavics and what are the Zipp's?

    I have a C60 with Vision Trimax T35's these are 18mm wide iirc, currently shod with 25c Michelin Lithion tyres and it still has a little extra room.
    My winter bike is exactly the same as my summer bike,,, but dirty...

    Mavics are 6 yrs old and "pre-wide era". Slow twitch.com says 15/20

    Zipp #'s are
    Brake Track Width (center) 24.73mm
    Max Width 26.53mm
    Clincher Bead Width 16.25mm

    I just want to have the right size tires regardless of brand ready for when the wheels arrive

    no idea about the specifics of the frame but the 25mm generally come up very large on wide rims. id play it safe and use 23mm tyres.

    I have 25mm Conti Gp4000iis on my C60 on wide carbon rims with no problems. They are a little tight under the fork crown but so would 23mm tyres. Mine is a disk braked frame though if that makes a difference.
