I just recently purchased a 7.3FX, and it's a great ride. I'm 6'2", 300+ and ride the 22.5".. and it fits great! In fact, that was one of the selling points, that it fit me so well.

The only thing I'd recommend a change on is the suspension seatpost, if your 7.2 comes with one. I've seen the 7.2's with and without it.. can't figure THAT one out! And the saddle, you might like it, but you'd be one of the few Try it out for a week, if it's still painful then yeaaah.

Only problem I've had with mine is the rear wheel. But I think that's a combo of my big butt and, as someone else put it, my "freaky" quads . I keep popping spokes when I'm taking off, but that will soon be alleviated, providing the LBS ever gets the parts for my new wheel build in.

Enjoy it! They are great (and very popular!) rides
