Carbon Oversized Pulley System – 14T/18T, Full Carbon Cage, Coated Bearings

Product Introduction

You walk into the garage. Your bike is clean, tuned, and ready. But something‘s missing — that extra detail that makes it yours. Not just another bike with the same parts everyone else has. This pulley system changes the look of your drivetrain at first glance. Full carbon cage replaces the stock aluminum one. 14-tooth upper and 18-tooth lower pulleys. Coated bearings that spin smoother and last longer. Not about saving watts you’ll never feel. It‘s about building a bike that reflects how much you care about the details. Install it yourself in about 30 minutes. Then step back and look at what you’ve built.

Product Features

🎨 Visual upgrade — your drivetrain, redefined
The carbon cage and machined pulleys change the look of your bike instantly. It‘s the difference between “stock” and “built.”

🛡️ Full carbon cage — not nylon composite
Most oversized pulley systems use nylon composite cages. This one uses 100% real carbon fiber. Lighter, stiffer, and visually unmistakable.

⚙️ 14T/18T oversized pulleys — less friction, smoother drivetrain
Larger pulleys reduce chain articulation and drivetrain friction. The difference is small — but for riders who care about every detail, it matters.

🔩 Coated bearings — smoother, longer-lasting
Coated bearings reduce friction and resist corrosion better than standard bearings. They stay smooth longer, ride after ride.

🏁 Hand-built — not mass-produced
Every unit is assembled by hand. Not a factory line. Not automated. Someone built this specifically for a bike like yours.
