Description

The special machining of our SPCE BMX rear sprocket, makes it possible at the spline level to lighten it. This is why you can maintain a high power transmission capacity. Compatible with all freewheel bodies which are a cassette type.

The SPCE stainless steel rear sprocket is CNC machined in France. This material guarantees lightness and, above all, very high product resistance thanks to heat treatment. This treatment results in greater hardness and longevity.

The SPCE drivetrain kit is a definite advantage for riders. In fact, our SPCE drivetrain brings a measured gain of between 2 and 2.8% on lap times.

We offer a wide choice of gears. We therefore recommend that you take a look at our development tables to choose the right rear sprocket and increase your performance.

  • Our SPCE BMX rear sprocket is suitable for all rider categories, including “Elite”.
  • Use of the SPCE chain tensioner is mandatory to obtain the advertised results!
  • Rear sprocket only compatible with the SPCE chain, chainring and chain tensioner.
  • UCI approved
  • Patent pending
  • Drapeau français Designed and developed by AllYoogs®. Made in France
