Problem Solvers Chain Tensioner and Derailleur Hanger


  • Product Description

      This little device will stop your rear wheel moving forward when you stomp on the pedals. It will also give you a derailleur hanger to bolt a derailleur onto. That makes it very useful for converting track frames into geared city bikes.

      Will take either a 10mm solid axle, or a quick-release skewer.

      For frames with track ends (also called rearward-facing horizontal dropouts).
