using some old Scott pads, the aluminum carbon wrapped extensions from some circa 2000 projectX bars, and the clamps from a pair of jammers I came up with a set of clip-ons just over 300g.
I wish aerobar manfs would put their stuff on a diet. Cut out all the adjustability and produce multiple sizes. Why a kilo is an acceptable weigh for a one piece aerobar beats me when one can build an entire frame set in that realm.
Yeah, i've heard that mountain bike handlebars will fit into the Jammers. If the Schmolkes can get theirs down to like 125g----500grams for a shorty aero bar is absurd. I'm surprised that a major component maker (Profile, Syntace, OVAL) havent came out with a super light aero bar.
I just saw the Carbon Profile GT's on www.trisports.com
but no weight is listed.
