    Ridley Gladius Road Frame Question on Top Tube Lengths

    Does anyone own and/or could measure their top tube on Ridley frames? I'm attaching what is considered frame measurements published by sellers.

    -The top tubes seem very long for the seat tube sizing.
    -Are these true centre to centre measurements?


    Any help on this would be appreciated.

    For instance, the 57cm C2C seat tube is a 59cm C2C top tube. Odd. Is this correct?

    Given how the tt measurements bounce around, I wouldn't put too much stock into the chart anyway... I mean, why would the 57cm ST bike have a 59cm TT and the 58 ST bike have a 57.5 TT. Don't even get me started on the 59cm ST bike...

    This quite common these days due to sloping top tubes and such. Creates a more aggressive position, siffer triangle and more comfortable ride due to more exposed seat post. My bike has a 48cm c-c seat tube and a 52.5 top tube, the difference only seems to be becoming more drastic too. Top tube is the only measurement that should really matter for getting the bike to fit you, as a longer seatpost can always be used.
