Really large S-3 road frame
True Temper S-3 is about the thinnest wall steel I can buy and it takes a lot of care to weld it. This frame is for a 6'5" rider and it weighs a scant 3 lbs. 13 oz. , a weight you would expect of an aluminum frame, not a steel frame of this size. I didn't use the S-3 seat tube, head tube or chainstays as I feel they would not be rigid enough. Even tough I didn't use the whole set, the frame still came out lighter than I would have expected. I used a sleeve at the top of the 1 1/4" diameter OX seat tube so that a 27.2 seatpost could fit.
I used and OX head tube with a 1.2 MM wall , thinner than I normally use so I put on these old-style re-enforcements at both ends....kind of like an early '90's Ibis frame.
