Elitest thrill junkie
Mullet will probably be my next AM/Enduro/all terrain bike. 29er F and R is too much of a drag at higher speeds in medium radius turns IME, with any kind of significant casing and tire width, they burn a lot of speed here that you have to make up for, but modern geometry has solved the tight technical handling issues and they'll keep speed better in sections and avoid wheel-catchers like mad. I think mullet would help to leverage these advantages and since the rear just follows the front, I think that's where I would like to see a 29er on such bike. The only issue is keeping reasonable geometry and not jacking the ST angle way rearward, which would be happening on a haphazardly designed "mullet".
