Questions fréquentes
How do I choose my BMX Race drivetrain?
It all starts with the gearing: a chainring paired with a sprocket sets your gear development. A 44/16 setup is a versatile standard; you then adjust it to suit the track and the rider's power.
What chainring size should I choose?
The chainring is chosen together with the sprocket to set the gearing. A 44-tooth paired with a 16-tooth sprocket gives a versatile ratio; go up or down in teeth depending on the track.
Chromoly or aluminium for drivetrain parts?
7075 aluminium is light and favoured in competition, while chromoly is tougher for young riders or intensive training. In BMX Race you want the best weight-to-stiffness ratio.
Are chainrings universal?
They mount with 4 or 5 bolts (BCD) or directly on the spindle (spline). Check your crankset's mounting type before ordering a BMX Race chainring.
Is shipping free?
Yes: shipping is free within mainland France from €99 of purchase. Below that, the cost is shown at checkout according to weight and the chosen shipping method.
