A seatpost collar with two threaded eyelets for attaching a rear bike rack.
A pivoting stainless steel threaded insert reduces fatiguing of the pinch bolt.
Use this when your bike frame has no rack-mount eyelets at the top section of the rear triangle. Replaces your existing seatpost collar.
Available in Black or Silver for 30mm, 32mm, and 35mm seatposts.
