A highly efficient solution for achieving precise fits between seat tubes and frame tubes

The Seat Tube Reamer is a compact, user-friendly, and robust modular unit designed for swift operation and compatibility with various frame types. Its primary function is to create a precise fit between the seat tube and the bicycle frame tube, accomplished by adapting the reamer on the machine to the required format. What typically consumes a considerable amount of time can now be achieved in less than ten seconds.

The machine’s frame holder is adjustable, ensuring suitability for all frame types. Foot-operated, it features an electric foot control lever that sets the machine’s reaming tool spinning at high speed, effectively reaming the tube to the necessary format. To prevent overheating, the machine incorporates a liquid cooling tank with an adjustable tap.

The Seat Tube Reamer offers both ease of use and speed, resulting in significant time and labor cost savings. It’s a highly efficient solution for achieving precise fits between seat tubes and frame tubes, ultimately contributing to smoother bicycle assembly processes.
