I recently purchased an entry level Iron Horse Maverick Trail. I have a new set of Shimano Deore LX shifters and a new cassette and chain to make it a 9 speed but I'd really like to lighten the bike up by a few pounds. Does anyone has an idea or two with regards to component changes that would help. The bike is all stock right now including the grip shifters and the manually adjustable rear shock. Thanks Wardie
