Careful about your choice of saddle. The other day, I tried the Butterfly (I think that was it) on TrekHawk's Juliana and could get off the bike without really concentrating on spreading my legs (no smart remarks, please). In my opinion, it's just too wide and poofy for a mtb saddle. I'm sure there are those that like it just fine.

Also, a pink saddle will get filthy really fast and dirt in the scuff marks will probably be permanently ingrained.

Just a couple of thoughts since these "accessories" aren't cheap.
