Based on Pedaltrain's popular PT-JR crankset, the Classic JR takes this proven design and makes it even better! First, you can stop trying to thread your cables through those tiny portholes: the Classic JR's open design makes mounting your power supplies a breeze. On top of that, Pedaltrain gave the Classic JR a wider stance and increased its rise by a whole inch, so it can accommodate just about any power supply or switching system you might have in your platform. Get a Classic JR and see why!
