BMX Teeth Less chainring 4mm – 11/128

Our lightweight 4mm Teeth Less chainring is an excellent alternative for riders who have reached the end of their SPCK chain kit’s capacity, or for riders who want to improve their performance with a standard chain.
Riders will notice the smoothness and improvements from the very first pedal stroke.

Advantages of the lightweight TLS 4 bolt – 4mm :
– 2 times less lateral chain friction
– improved mechanical efficiency
– weight saving
– smoother pedalling
– compatible with 11/128 and 3/32 chains

The special shape of the lightweight 4-bolt TLS is the result of optimisation using Finite Element Method (FEM) simulation. This increases resistance and significantly reduces weight. The TLS 4-bolt chainring is designed for a standard chain.

The AllYoogs® front sprockets are machined in France by CNC from 7075 aluminium (much 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.
