and the answer is?? just fit? if so, then i can see that. ive never used a setback post, and tend to ride pretty big frames with traditional/ish geometry. maybe if i were riding something compact id see the benefit. so for the record, is a seatpost with cradle that curves back slightly (not centered with the seat post, and seat tube) considered a set back post? or are we talking major set back like those bendy thomson posts?
