The Reynolds has developed a newer stainless steel called 931, which is more akin to 853 in terms of strength but is easier to draw into smaller tubes.

The properties of the metal ultimate tensile strengthis 1200~1350 MPa. At around 1300 MPa tensile strength depending on heat-treatment,

this steel is strong enough to be cold-drawn to tube walls around 0.4mm thick, offering light, competitive frame weights for durable frames.


The RSL 931 is your cycling life of steel.

BB30 - New BB Industrial Standard

The BB30 system is new BB industrial standard. The BB30 crankset is 10% stiffer, 20% lighter, and provides 300% more ankle clearance than the GXP system. The results are an impressive increase in rigidity in the frame and crankset, better durability, lighter weight, and more ergonomic design for the crankset. With so many advantages, it’s hard to deny the validity of this system.

The maintenance of steel frame

The charming slim tube, the timeless epic, faithful paddle power, excellent rough road absorption, these steel bike character is too strong temptation for the cyclist to resist. All Speed one bike have complicated electroplating rust treatment when it ship out the factory.
