Steering uses a gears and apparently steering response speed can be tuned by adjusting the gear ratios:

I'd love to give one a go, who knows, It might be working. I suppose advancements in tyre technologies to get those puppies down to sub 900grams is required.

Why fore is the saddle on the 39er drawn as set up for a 38" inseam, while bars, reach and cranks are at the same spacing as the 29er? He'll have to CG a suitably stilt legged rider to go along with his CG bike.

Chain & sprockets for steering...

Just think of the KOM's you'll crush with the correct steering ratio!

Wont be long before 36ers come back into fashion and prove 39ers sucked all along
