Because it's a fixed gear bike without gear changes, we want you to ride it with a gear ratio that suits you.
This idea led to the creation of BROTURES' original cog.

We have created something that is easy to use, in terms of price, material, and number of teeth.
The optimum gear ratio for city driving is around 3 to 2.7.
We offer 15T, 17T, and 18T, which are compatible with each other and take skid points into consideration.
The material is rust-resistant stainless steel.
The cogs are machined by CNC machining and are boldly hollowed out to achieve both strength and light weight. (The 15T is not hollowed out.)
Despite all this attention to detail, the price is less than half that of branded products, and the teeth are just the right amount of precision.
This is the perfect item for stepping up from a completed bike.
