Anyone experimented with different size wheels?

I was reading the interview with Brandon Sloan where one of the questions was:

Are there any particular design difficulties to overcome when you’re building a 29er version of an existing 26in model?

That’s a good question. On the 29er side of things, there’s still trouble fitting the wheels in, especially with our geometry – low bottom brackets, short chainstays, roomy top tubes and relatively slack angles… The biggest problem is the chainstays. These are really short, because we like a nice nimble bike, and putting the big wheel in there makes it difficult to get the travel we need with the tyre and chainring clearance clearances and the stiffness that we need. It’s tight.

It got me wondering if anyone has experimented with a larger front wheel and a smaller back wheel similar to motocross bikes? Maybe you could get the smooth rolling front end and the agility from short chainstays.

Yup, there are a fair few 69ers on the market. In fact most fairly slack 140mm hardtails will happily take a 100mm travel 29r fork and front wheel...

Cheers for that. The 69er concept completely passed me by :oops:

I see that Trek have done a few.

Specialized used? to make a 26 front 24 rear. PITA sorting wheels.
