Alternator 1.0 / 1.5 Swing Plate Left Non-driveside Thru Axle with Fender Mount - 3797

The Salsa Alternator 1.0 / 1.5 Swing Plate Left (Non-Driveside) Thru Axle with Fender Mount is a direct-replacement dropout plate for Salsa frames that use the Alternator 1.0 or 1.5 system. It restores the fore-aft adjustability that makes Alternator dropouts valuable for dialing in rear-wheel position, drivetrain fit, and handling—while retaining a dedicated fender mount for clean, secure coverage in wet conditions.
