Hi, if I had a 15lb bike, I would at least like to be able to ride it without damage. Some pix would be nice, let us know when you have some to share, from memory my Rigi is around 20lb, I have not used to much Ti or OMAS on it, I have 36 spoke wheels with 400gram rims, I am sure if I used more Ti, alloy and OMAS I could get that down, I am not going to weight it again until I have the Gian Robert FD rebuilt, hollow pin chain at the right length, changed the HB/stem to 3ttt & fit the GPM headset, on a side note, does anyone know which Rigi frame is lighter, stainless steel or steel?........regards wayne davidson invers NZ........
