STEEL IS REAL  !
 
This seamless air-hardening steel tube sets new standards for professional cycle frames and proves that steel still has a future at the highest levels. It is suitable for TIG welding and brazing, using lugged or lugless construction. The production process ensures tight tolerance, gauge tubes. The strength to weight ratio of 853 is close to that of quality titanium frames. A normal chrome molybdenum steel will lose strength in the joints after the heat has been applied.

This material (853) INCREASES in strength as the frame cools to strengths well in excess of the delivered values shown above. This unique air hardening property of Reynolds 853 provides additional stiffness through reduced microyielding at the joints, allowing stiffer frames with excellent fatigue strength (when compared to standard chrome molybdenum) and a superior ride quality from the finished frame. On road and  touring frames we recommend the use of 631 or 725 fork blades with 853 frames.

We offer this tube set in many sizes for custom framebuilders, and is suitable for lightweight frames, strong/tall riders and has also been specified for free-ride and BMX frames due to its' high impact strength.
