Synergetic Chainstays

Synergetic Chainstays

When you introduce asymmetry into a frame design, you have to restore balance. Our Synergetic Chainstays serve this function. Their unique design allows clearance for full-sized chainrings and 28c tires. They let us run a sub-41cm chainstay with a 160 mm disc rotor.
