Salsa Post-Lock Rack Mount


A seatpost mount with two threaded eyelets for attaching a rear bike rack. (Not a seatpost collar.) Positioned along the exposed portion of a seatpost.
Available for 27.2mm, 30.9mm and 31.6mm seatposts.


This seatpost mount by Salsa come with two threaded eyelets for attaching a rear bike rack.  This secures to your seatpost with a single allen bolt. A smooth bore on the inside of the collar protects your seatpost from scratches.

This is a solid solution for frames that don’t have rack mounts on the top section of the rear triangle, or for when using the rack mounts causes the rack to be non-level (such as with some small frames).

Available for 27.2mm, 30.9mm and 31.6mm seatposts.

**This is not a seatpost collar — this gets positioned along the exposed portion of a seatpost and can be adjusted up and down on the seatpost as needed.

For a seatpost collar with threaded rack-mount eyelets, see: Salsa Rack-Lock Seatpost Clamp

    This part is a problem solver !!!!

    I purchased this part since my bike frame did not have the upper mounting points to attach a cargo rack. This part does NOT act as a seat post clamp. As a result, I can slide this part onto the seat post and tighten it at any height needed to mount the rack. Also, I can use it on any of my bikes that have a 27.2 mm seat post.

    Good Company to Deal With

    The website was clear and the presentation of the product was easy to understand. They kept me on top of the order’s progress. And this Salsa Rack Mount is an excellent, well-made product. I’d recommend it to anyone. It helped me get a perfect fit for a rear rack.

    Just what I needed

    No Salsa rack locks are in stock anywhere online. Stumbled across this Salsa post-lock on campfire cycling. Awesome find! Fits my bike perfectly and easy to install. Unfortunately Salsa’s alternator rack would not work for my Salsa Timberjack. So I installed an Old Man Mountain rack instead. Although the OMM rack has a “fit kit” that comes with pucks to mount the rack extenders to your seat stays, I decided to use the Salsa post-lock instead, seemed more robust of a setup to me. Also I’m still able to make complete use of my dropper post travel with it installed. Works great if your bike does not have braze on’s for mounting a rack!

    Nothing but great experiences w/ Campfire

    Haven’t used it yet but I’m sure it will work just fine. The main review here is for Campfire and their commitment to getting things right.
