Tensor de cadena con patilla de cambio Problem Solvers

The Problem Solvers Chain Tensioner with Derailleur Hanger is a practical solution for running a single-speed drivetrain on a frame with vertical dropouts. It replaces the standard derailleur hanger and uses a spring-loaded pulley to maintain consistent chain tension — keeping your drivetrain quiet and engaged without the need for a dedicated single-speed frame.

Designed for riders converting a geared frame to single-speed, it mounts directly at the derailleur hanger interface and keeps setup straightforward. A reliable choice for commuters and urban riders who want a clean, low-maintenance build without changing frames.
