The CK-1 crank from Promax is a rare offering in the BMX world being constructed from carbon fibre. A few companies have tried before, but haven't quite cracked the formula. Promax has the experience and the know-how to make a BMX race set of carbon cranks work at the top level.
Manufactured with a 30mm spindle proves that this BMX company knows what they are doing when it comes to maximising strength and stiffness in this vital component.
These cranks offer direct-mount chainring compatibility for additional weight savings, but honestly, not many BMX racers run this set up. Our tip is to grab the 4-bolt 104 BCD chainring adapter, available separately. Then any of your existing 4-bolt chainrings will bolt straight up to these carbon beauties.
