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.
