    New 29ers quicker uphill than good rigid hybrids.

    It's hard to undetstand why, but both myself and my wife feel that our new bikes, Cannondale Trail SL2 29er, and her Specialized Jett Expert go uphill better than our last bikes, Cannondale rigid hybrids (bad boy and quick feminine)

    The old bikes are lighter, stiffer, rigid and with slick tyres, but at the top of hills we did regularly, we both have more puff left, and we've ridden them marginally faster now on the new bikes.

    Can anyone explain this? Is it a common phenomenon? Not complaining, obviously.


    Cheers

    That's not a very controlled experiment, is it? I would guess it's mostly new bike excitement. A few pounds of weight will hardly make a difference.

    RIGID, not "ridged" or "ridgid"
    PEDAL, not "peddle." Unless you're selling stuff

    I do kinda buy that theory seat boy, and you're not the first to make that suggestion.

    We both feel fresher after rides, as though we have used less energy.

    You are right about it not being very scientific though.

    Different Geometry?
    Steeper seat angle?

    The bike certainly feels longer when out of the saddle. Sounds bit odd, I know.

    Better components?

    Too much it could be and not enough info.
    Just stick it in granny and start grinding.

    It's either psychological or the bike's geometry is better for climbing. I was amazed at how much my climbing improved just by changing to drop bars...Not saying that drop bars are better for climbing, just that the change in geometry made me climb in a much more efficient way.

    The fact that you feel fresher at the end of a ride could be entirely down to the tyres or it could be that the geometry suits you better (maybe a bit of both). I think people underestimate how much good bike fit effects your riding...Moving your saddle or bars by as little as 1cm can have a big effect on how fresh you feel, how efficient you are and how much power you can produce.

    I climb better aerobically on my 29er that has higher handlebars than my 26er. Could be any number of things.....quite frankly the reasons I see as unimportant, only my times.

    Your in better shape or the wheels-tire combination is lighter.

    I saw a vid that explains why. It has to do with the sine wave of your power stroke. Bigger tires have a longer power stroke and will not spin out as fast as a 26" tire. The 26" tire has a very short power stroke vs. the 29' tire. This vid is on this board somewhere. They were showing an out of the saddle climb up a steep dry climb were the 26" was prone to spin out. If you are in the saddle and not hammering down I do not think that you would notice much difference. Moreover, the front tire is more planted on a 29" so if you are used to pushing down you front tire you might notice a difference.

    ^^^Either this or placebo IMO.
