BROTURES TECH CHAINRING

“From Code to Cadence” — The Philosophy Behind the Design

The starting point for this product was an old code disk.
Back when computers stored data through a series of punched holes—
we reimagined that inorganic code as the rhythmic rotation of a track bike, and that idea became the origin of the TECH CHAINRING.

A design where form serves purpose, balancing lightweight construction with true functionality.
We set out to create a dynamic shape—one that is only completed when you pedal and bring the crank to life.

TECH CHAINRING is CNC-machined from aircraft-grade 7075-T6 aluminum, achieving both stiffness and lightness.
It’s built to handle high-load movements—from city riding to tracklocross and tricks.
By improving chainline precision and reducing tension fluctuation, it delivers light initial pedal stroke and smooth rotation.

The name itself reflects the product’s core philosophy:
to embody the very beauty of “riding with pure pleasure.”

Three Sprocket Sizes to Match Your Style

The size lineup isn’t limited to the popular 49T and 47T, but also includes options suitable for tricks and off-road riding.

With strength sufficient for racing scenarios, the TECH CHAINRING is sure to perform exceptionally well even in the increasingly popular tracklocross scene.

43T: Ideal for tracklocross (TracX) and FGFS setups
47T: Perfect for street actions such as skids and tricks
49T: Suited for high-cadence sprints and track riding

These variations are designed to let you freely customize your gear setup and enjoy playing with your track bike.
With BROTURES TRACK COG offering many different sizes, you can experiment with various combinations to find your own optimal setup.

Change the way you ride, change your style.
The TECH CHAINRING is a component that embodies that very freedom.
