We has decades of experience in working with 4130 chrome-moly steel for its bike tube products.

Chrome-moly steels are the work horses of industry world-wide, because of the excellent combination of strength, ductility, workability, and reliability.
Speed one had developed new technology which called “SCUZZI Cr-Mo SPIRAL” and combined the spiral tubing shape.

The RS30 accommodates SCUZZI spiral which means the frame are 20% lighter and 30% stiffer.
With its SRAM Apex drivetrain and BB30 shell, plus Speed one Carbon Monocoque high performance carbon fiber fork,
the RS30 delivers the unique ride qualities of steel and race-worthy performance.

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 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.
