Rack-Locks are a great combination of style and functionality. They not only look good but also securely hold your seatpost in place. What's more, they offer a mounting spot for the front struts of a rack. Here are its features: Max torque of 3–5Nm, made from AL-6061 Aluminum, has strong rack attachment points, a 34mm-wide rack mount threaded for M5 bolts, a stainless steel pivot and bolt. It comes in 30.0, 32.0, 35.0 and 35.4mm sizes, is black anodized with a laser-etched logo, and a 32.0mm collar weighs 45g.

Using your Salsa Rack - Lock Seat Collar is easy. First, choose the right size collar for your seatpost. Then, slide the collar onto the seatpost. Tighten the bolts using a torque wrench, aiming for a torque of 3 - 5 Nm. This will ensure the collar holds the seatpost firmly and also provides a stable mounting point for your rack. When mounting the rack, use M5 bolts on the 34mm - wide rack mount. As for maintenance, regularly check the bolts for tightness. If they seem loose, gently tighten them to the recommended torque. Clean the collar with a mild soap and water solution. Avoid using harsh chemicals that could damage the black anodized finish. Also, keep an eye on the stainless - steel pivot and bolt for any signs of wear and tear.
