Most Popular RockyMounts for 2020 GMC Sierra 2500

Good, solid product. Easy to install.

This is not the first bolt-on 12mm thru-axle fork mount I've attempted to use, but it IS the only one I've ever actually been able to use properly. I'm always please with RockyMounts quality and this is no different!

Good mount over-all. Item was delivered without the packing straps. Not sure if the package was opened prior to shipping. There were no missing parts. The mount seems to function normally. I do have one complaint - the mount is not level when attached to my Ridgeline 2" hitch. My hitch is in perfect condition - unused prior to the purchase of this mount. The mounting bolt for the hitch is fully tight, but still the mount is crooked to right by 1 inch. Oh well - not a deal breaker.

We have two e-bikes and researched for a rack substantial enough to carry them long distances. The RockyMounts Monorail is doing the trick. We remove the batteries and seats. Based on other's advice, we put pieces of foam pipe insulation over the straps and braces that contact the bikes. Also, just for overkill, put additional cinch straps over the front tire rim at the wheel support. I also fabricated a license plate holder because the plate is obstructed on the SUV. The quality of construction and ease of assembly are both outstanding.
