Advice to customer want to modification:
1. If you are single chainring, recommend change to narrow wide tooth. Performance will better

2. More tooth means more likely to round, but only recommend add 1 tooth. For example, if you are using 11T, the max you can change is 12T. 13T is too big for you.

Polyoxymethylene (POM), also known as acetal, polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability.

POM is characterized by its high strength, hardness and rigidity to −40 °C.

Typical applications for POM include high-performance engineering components such as small gear wheels, eyeglass frames, ball bearings, ski bindings, fasteners, guns, knife handles, and lock systems. The material is widely used in the automotive and consumer electronics industry.
