Can anyone here comment on riding, say, a 36 vs. a Schlumpf 24?
I’m very interested in high-performance high-speed, and I’ve been thinking a lot recently about possible advantages and disadvantages of big wheels. I’ve never gotten the chance to try anything geared or even a giraffe.
My thoughts have been that the differences are mainly between stability and energy.
- Half the wheel size will mean half the moment of inertia for the same speed, ie, the energy going into making the wheel turn faster or slower (as opposed to moving you) is half. That assumes that the mass of the wheel is half, but I think it's probably much less (thinner tires, rim), so the difference would be even greater.
Does a 24 schlumpf feel more responsive than a standard 36?
I’m seeing two main parts to this one
- Larger wheel diameter. As you fall forward on a wheel, the point of contact of the wheel with the ground moves forward. The actual distance the point moves forward would be proportional to the wheel-size. Does a 24 guni feel like it has a smaller balancing envelope?
- Angular momentum, wheel size over bumps. On my 36" I roll over bumps and usually I don't have to do anything, just loosen up and take them. On my 24 (non-geared), if I hit a bump it slows down the wheel and I have to recover. Obviously the wheel size has something to do with it, but I think it's also related to the angular momentum of the wheel. Since a smaller wheel at the same speed has much less momentum, would it be more prone to upsets from terrain?
This is not about geared vs ungeared. Big or small I’ll be gearing up. Comparing the 24 geared with a standard 36 just seems like good way to test for differences in wheel sizes.
