Hi folks,
Im looking for new tubular rims and tyres. Rim width (external) is 25m.
Can I fit on these wheels 23mm tubular tyres or not? :?:

Thanks for help

    Technically you can, but you may end up with a small 'step' between rim edge and tyre..

    It depends on how the tyre actually measures up. Different 23mm tyres actually come out anywhere between 22 and 25mm. Schwalbe Pro One, for instance, come up very large; Challenge Strada very small. Dry fit them and have a look.

    Wow, if the rim is 25 m wide, how big's the bike? :-)
  • In my case I want to know, if is possible fitting 23mm tubular tyres to these two wheelsets:

    1 - Prime RR-50 Carbon Tubular Road Wheelset (for training) (Rim Width: 25mm)
    2 - Campagnolo Bora One 50 tubular wheels (for races) (Rim Width: 24,2mm)

    For both - recomendation is 25mm tubular tyres. If this is the only options, I will live with them.
