Quite honestly, I don't mind if my bike is slower than a 26 " or maybe even a 650 B (those tri-bikes sucked back then as well)

What I will say is that every time I get on board my bike I grin from ear to ear and when we hit the thick sand I turn around and laugh at everyone else getting stuck.

So quite honestly, if 29'er is slower then I don't mind a slow bike.

Looking at the Para's spreadsheets, even the baby gears gain more ground.

So the key would be to just maintain the cadence.

More development* = bigger gear

bigger gear = I must use more energy to turn it.

 

Therefore I better be a damn site fitter than the O I'm trying to beat If I want to make use of the development*

 

THere is no such thing as getting something for nothing**

 

*Development is the linear distance a bike moves per revolution of the wheel for a given gearing.

What I expect you meant is "per revolution of the crank". The linear distance per revolution of the wheel does not change...unless you move from a 26er to a 29er...which is why a given gear ratio on a 26er has a larger development on a 29er.

Well, with all conditions the same and at the same cadence, a 29er will be faster.

You mean in the same gear right? Of course a 29er will go faster if you pedal the same gear at the same cadence - you go further per pedal stroke. Silly statement though - it's like saying "you'll go faster in a 53x11 than a 39x23 if your cadence is the same".

 

Faster sure but you'll be bleeding out of both ears.

Eldron, you will also go faster on a Lynskey if you pedal at the same speed????

 

Pah! Lynskey's are for old dudes who spend too much time making money and not enough time riding their bikes :P

 

Mmmmmm PRO29.....love the BB work....and warped tubing....
