RockyMounts BrassKnuckles

The Rocky Mounts BrassKnuckles Up-right bike rack gets its name from its iconic grip on the pivoting arm of the rack.  This makes it easy for the user to load and unload their bike securely and easily.   Contrasting most Up-right style bike racks that can accomodate a 29er, this rack is extremely low profile and more aerodynamic than any other up-right on the road.  When not toting a bike the rack  is 1/2 the height of its best competition (Thule SideArm, Yakima HighRoller).  Plus, it is available in a variety of colors to complement your vehicle and bike.

Availability: In stock

I really like the BrassKnuckles from RockyMounts. RockyMounts as a company is very bike focused and always do a great job designing their products with the user in mind.

The BrassKnuckles is one of the easiest racks to assemble and very simple to install. On my old rack, I had to remove my front tire. With the BrassKnuckles you leave the tire on, which saves me time and the interior of my car. Plus it works with all the bikes in our garage and both of our crossbar systems!

VEHICLE FIT TIP: Some vehicles have back hatches that love to get in the way of bike rack wheel trays. The BrassKnuckle's design pushes the rack forward on the crossbars and allows for much more rear hatch clearance.

INSTALLATION TIP: The only real complaint I have is switching the arm to the opposite side. Even with the bolts all the way loose, the arm can be difficult to remove. Ask a friend for help and save yourself some frustration. As your friend holds the rack, move the arm back and forth as you pull out. Sometimes I will use a rubber mallet and a deep socket to help get it started. (Posted on 10/26/2016)
