SEAT POST: ProLite Seat Post In our never-ending quest to make our bikes lighter, we've
replaced our 2003 edition seat post with the ProLite seat
post made out of double-butted 6061-T6 aluminum. We save 90
grams. The ProLite also incorporates an optional rear reflector
bracket for those bikes without rear racks. The SuperOversize
diameter tubing makes it just about the strongest seat post
on the market. As a final touch, we use a hard bead blast
finish that is extremely scratch resistant and will retain
its beautiful looks year after year.
