True Temper's newest steel tubing is the S3 Super Strength Steel Series. This alloy makes possible top tubes and down tubes having end butts of a weight shaving 0.5mm and center sections of 0.4mm. This alloy with its special heat treatment is used to create the S3 Super Strength Steel tube set. This makes a compact style (sloping top tube) frame that weighs only 2.85 pounds (1295 grams) for riders who want the lightest weight possible.
真強.......上下管兩端可抽到0.5mm(OX platinum只能到0.7),中央可以到0.4mm
做成壓縮車架可以做到1295g
這重量已經讓很多鋁車難看了
