Look, he wants a 24, so he is going to get a 24. Does there need to be a point of a 24 trials bike? Whats the point of using hydroforming? There isnt a point, but it is change.
And no, people are not trying to suggest that Marc Caisso would have been a better rider if he had been riding a 24" trials bike.
EDIT: G, im riding a 24 Echo now and its really, really nice. I prefer it from my mod alot more. I was running a very low echo stem, 20 x 120. It was horrible on 2 wheels but felt quite nice on the back wheel. I've put a mod stem on and it feels alot more stable and still feels nice on the rear wheel.
Look forward to seeing your next video on the 24 mate!
