I have a 2001 (I think) Litespeed Blue Ridge. Nice Bike, but I've noticed that compared to some other bikes, even steel framed Surlys, it's heavy. I have Ultegra stuff on it, an Deore XT chain and Cassette, but I do have a Dimensions stem, and a Velo Orange Grand Cru seat post. I also have Mavic A719s. So, what do I need to do to drop weight on this thing?
