I've made a couple different seats. None of them quite as nice as my buddy's Bacchetta Giro, which is the bike that I'm basically copying. (Spirit with 2 700c wheels / Highroller with "atomic zombie" rear axle, however you want to look at it)

I like everything else about my build, but the seat is less than ideal. Comfort and storage are key, and I might just plunk down some bucks to ensure I get a good, comfortable ride even at 100+ miles.

Bacchetta (and obstensibly other) bike seats are made for round or oval tubes. Has anyone had any luck or experience trying to attach a commercially made seat to our square tube jobbies? I'm guessing some kind of adapter or jig might have to be made.

I figured this would be the place to ask instead of asking the name brand folks.
