Have to say, I've never really been into weight saving on bike components, I've always gone for strength and burliness... but since buying light wheels and tyres for the Canyon, it flies!
Proof is in the pudding too, beat my PB on a long climb by over 2 mins. That is all-time too, the Canyon weighs just under 36lb and I got up there quicker than on any short travel/trail bike I've owned!

Does this now prove that 29ers are poo? :wink:

    Its BS though - in what world are two identical weight wheels built with either all the weight in the hub or all the weight in the rims. The hubs are the same weight on most bikes, so the weight of the rim changes with wheel size - a ZTR Crest 26 weighs 340g per rim, the same rim in 29" weighs 380g, a 650B version weighs 355g so what i would like to see is the proportional sizes and weights represented in the same experiment.

    Or am I misunderstanding the point?

    We should all ride FS Penny Farthings with a dropper post. That would end the big wheel, small wheel debate.

    no it means that heavy rims/tyres don't roll as fast as light rims/tyres - this is nothing new

    but it is also saying that the closer the mass is to the hub, the faster the wheel.

    So as 29er rims/tyres are bigger and the weight is further from the hub, they inherently roll slower than the equivalent 26er setup.

    Was that supposed to be scientifically conclusive? How do simple plastic discs freewheeling down a couple of metal rods prove anything about complex bike wheels being driven by pedal power?

    You can work it out with a pencil, paper and a sliderule, but it doesn't make for awesome Youtube.

    I am convinced I am now going to go to the shed and wrap 2 kilos of roofing lead round each wheel hub. I am going to go soooooo fast I will be winning the next World XC event. As long as the course for the XC race is held on 2 smooth steel rods that is.

    Next years big development will be 24" wheels then two years later a compromise of 25" will be released and marketed as having all the advantages of 24" and 26" with none of the disadvantages of either.

    Doesn't take into account rolling resistance, in particular energy losses due to tyre carcass deflection - in which case the bigger diameter tyre wins every time.
