Alternator 2.0 is the latest iteration of Salsa’s adjustable dropout system. Alternator 2.0 Dropouts are a modular system consisting of replaceable dropout plates and fixing hardware. They are specifically designed for, and only compatible with, Salsa frames using the 2.0 system. Frames designed around the first-generation Alternator dropout system are not compatible with the 2.0 system parts, and frames designed around the Alternator 2.0 dropout system are not backward compatible with first generation Alternator dropout plates and hardware. Alternator 2.0 Dropout plates are compatible with frames featuring 142, 148, 177, or 197mm spacing. Hardware kits must always be paired with the style of dropout plates being installed on the frame.
