SPCE drivetrain kit: a concept for top-level performance !

Our SPCE BMX Race drivetrain kit is first and foremost a global concept born in 2021 to improve performance up to the top level of the discipline!
Months of research and testing have gone into making this project a reality. Incomparable technical advantages felt from the first pedal stroke!

TECHNICAL ADVANTAGES OF OUR SPCE DRIVETRAIN KIT

  • The SPCE drivetrain kit for BMX Race is a definite advantage for riders. In fact, our SPCE drivetrain brings a measured gain of between 2 and 2.8% on lap times !
  • The SPCE kit reduces vibrations by increasing the number of teeth on the front sprocket and the rear sprocket (polygonal effect reduction and winding angle on the rear sprockets). Its operation is similar to a belt, but without the disadvantages (lower mechanical efficiency, imposed rear-wheel position, elasticity, etc.). All riders note a reduction in effort for the same development. Mechanical efficiency is improved.
  • The reduced pitch makes it possible to precisely adjust the position of the rear wheel compared with a conventional or half-link chain. The result is twice the precision of development adjustment. One tooth on the SPCE sprocket corresponds to approximately 1/2 tooth on a standard sprocket.
  • The smaller diameter of our front sprockets makes them easier to mount on different chassis. In fact, our SPCE 85-teeth front sprocket = ∅ 194 mm, while the diameter of a 52-teeth front sprocket =∅ 218.5 mm.
  • Front sprockets are CNC machined and made of 7075-T6 aluminium (71% stronger than 6061-T6) with hard anodising to increase durability.
  • The rear sprockets are made of stainless steel and heat-treated to increase hardness.
  • The tensioner absorbs the tight point and ensures constant chain tension thanks to a spring and stop system. It ensures that the chain always engages all the teeth of the rear sprocket, enabling high power to be transmitted. This prevents derailment.
  • The SPCE drivetrain kit is suitable up to the “ELITE” categories.  A project and a concept born with the help of several “PRO” riders to overcome the recurring problems of top-level riders!
  • Our SPCE drivetrain kit has been validated by the UCI.
  • The SPCE chain’s lifespan is dimensioned to achieve the same wear as an adult with a standard chain and BMX Race use. A balance between performance and durability.
  • The special dimensions of the SPCE chain require a front sprocket and a rear sprocket adapted to it. There is no compatibility with conventional drivetrains.
  • Since the height of the teeth is reduced, the risk of serious injury or tearing of clothing is minimized. The drivetrain’s reduced overall dimensions also contribute to this.
