    Hi Folks,

    I ride a Norco Java MTB, and a Giant TCR2 Roadie...

    On the Java, running slicks, I can average around 36 km/h spinning at what I
    guestimate to be a cadence of around 90 RPM... On the Giant, in a similar
    gear ratio, I can average about 27 km/h, with a cadence of around 80 RPM,
    but also get a lower back pain...

    Now, I've measured both bikes, being seat to bottom bracket, seat to stem,
    and front hub to handle bar. The only major measurement difference I can
    find is that the bars on the road bike are about 10 cm lower than on the
    mountain bike... Is this going to be the cause of my lower back pain? And
    would the best way to work with this, to be to take both bikes into the bike
    shop, and adjust the road bike to similar measurements as the MTB? I
    believe if I turn the Giant headstem over, I should raise the handlebars
    about 5 cm... Is this going to be enough??? Or is it a matter of suck it
    and see?

    Cheers,

    Andrew

    Very likely.

    You can do it yourself unless you want to try different size components.
