The bike I’m refering to is my old Giant Warp Ds2. It’s a FS bike! I have been letting my wife ride this bike while she waits to get her own. Its a pretty heavy bike but I figured I could make it a little lighter for her. Everything on the bike is stock! It has an aluminum frame but I think the rear triangle is steel. Not sure why it’s so heavy. Maybe you could help me with ideas. Thanks
