Salsa Post-Lock Rack Mount

Salsa says...... Our Post-Lock is an attachment point that can be positioned anywhere on your seatpost to provide a mounting for a rear rack. 

Strong rack attachment points

Threaded for M5 bolts
Stainless steel pivot and bolt
Available for 27.2, 30.9 and 31.6mm diameter seatposts

Post-Locks do not have a lip like our Lip-Lock, Flip-Lock, and Rack-Lock so therefore cannot be used as a seatpost clamp. Not recommended for carbon seatposts
