Description

Benefits of the Pack: SPCE BMX drivetrain kit

Pack includes: 1 chain + 1 front sprocket + 1 stainless steel sprocket + 1 chain tensioner.

The SPCE BMX 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 front sprocket and increase your performance.

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

To learn more about the concept of our chain kit, we advise you to read our article.

Special features :​​

* Our SPCE Drivetrain kit fits all BMX frames except the following brands : Meybo HSX, GT, 4NIX and the Meybo instant-engagement hubs.

The particular shape of the SPCE BMX front procket is the result of an optimization by finite element method simulation (FEM). This increases the resistance and considerably reduces the weight.
        • Centre distance : 104 mm – 4-bolt attachment for SPCE BMX chain
        • Size : 75 to 85 teeth – 5 mm
        • Weight : 97 g to 117 g depending on number of teeth

The AllYoogs® SPCE front sprocket are machined in France by CNC from 7075-T6 aluminum (stronger than 6061). This material guarantees a lightness and above all a very high resistance of the product thanks to the hard anodization. This treatment implies a greater longevity of our products.

The SPCE stainless steel cog 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.

        • Type : rear sprocket for Single-speed cassette
        • Size : 28 and 30 teeth – 4 mm
        • Weight : 37 to 42 g depending on number of teeth
        • Choose your SPCE front sprocket
 

Our SPCE chain tensioner fits on most* BMX Race frames to ensure constant chain tension and therefore solve the recurring problems riders have been having for years. Our product is discreet, compact and designed for single speed.

Advantages of the AllYoogs SPCE chain tensioner :

  • Tensioner that absorbs the tight point and ensures constant chain tension thanks to the spring and stop.
  • It permanently ensures the engagement of the chain in all the rear sprocket teeth, thus enabling the transmission of high levels of power.
  • Change the front sprocket in a few minutes, stress-free !
  • Tensioning the chain without moving the rear wheel.
  • The original tensioners ensure simply the rear wheel position and no longer intervene in chain tensioning.
  • Quick front sprocket change from 2 to 3 teeth (+1 and -1 minimum).
  • The large size of the bearing reduces its rotation speed, considerably increasing its lifetime and load capacity. It’s diameter also limits vibrations.
  •  Available in 10 mm bolt and 12, 15 and 20 mm axles
  • Tensioner sprocket in anti-friction and silent technical plastic.
  • The bracket fits between the frame and the wheel.
  • Completely rustproof
  • Easy to maintain and disassemble.
  • Use of the SPCE chain tensioner is mandatory to obtain the results announced for the SPCE drivetrain kit!
