If you need more information on installation and maintenance BMX chain kit, you’ll find answers to your questions in our FAQ.

SPCE BMX front sprocket

The special shape of the SPCE BMX front sprocket is the result of optimisation using Finite Element Method (FEM) simulation. This increases the resistance and considerably reduces the weight.

        • Axis distance : 104 mm – 4-bolt fixing for SPCE BMX chain
        • Size : 75 to 85 teeth – 5 mm
        • Weight : 97 g to 117 g depending on the number of teeth

        Choose your SPCE front sprocket

The AllYoogs® SPCE front sprockets are machined by CNC in France from 7075-T6 aluminium (stronger than 6061). This material guarantees a lightness and above all a very high resistance of the product thanks to the hard anodising. This treatment gives our products a longer life.

SPCE BMX stainless steel cog – onyx compatible

The SPCE stainless steel cog is machined by CNC in France. This material guarantees lightness and, above all, very high product resistance thanks to heat treatment. This treatment increases hardness and durability.

        • Type: rear sprocket for onyx single speed cassette
        • Size : 28 and 30 teeth – 5 mm
        • Weight : 39 to 43 g depending on the number of teeth

        Choose your SPCE cog

SPCE chain guide

Our SPCE chain guide fits most* BMX Race frames to guide the SPCE chain and ensure that all teeth are engaged on the rear sprocket. Our chain guide is compact and designed for single speed.

How to choose your SPCE drivetrain kit ?

 
 
1. Development calculated in mm with a 20 x 1.3/8 tyre

In the table below, find the value indicated at the intersection of the front sprocket and the rear sprockets.

For example: rear sprocket = 16 and front sprocket = 42. The value to be taken into account = 442.0

To obtain the SPCE equivalence :

In the table, find the value that is closest to the one found in the table above (equal or greater value).

Example with 442.0 : we advise you to use a 30 rear sprocket with a 79 front sprocket.
