“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.
“From Street to Track” — That Marks Your Style Anywhere
The TECH CHAINRING is compatible with major crank brands such as BROTURES BEAT, SUGINO 75 CRANK, and DURA-ACE.
It allows easy upgrades from existing cranks, offering a wide range of customization options—from street riding to tracklocross and gravel.
The 43T is ideal for skids and wheelies when paired with a HOOKUP BAR.
The 47T and 49T, combined with a track cog, balance high-cadence stability with direct torque transfer.
Customization isn’t the end—it comes alive through riding.
That is the true significance of the TECH CHAINRING.
Change the way you ride, change your style.
The TECH CHAINRING is a component that embodies that very freedom.
