Question:

Hi, I am looking for a light-weight single bike carrier for my 2016 Mazda Miata with a 1 1/4inch hitch, and am wondering about the differences between the Rocky Mounts Monorail rack and the Rocky Mounts High Noon rack. Ill be carrying either a carbon road bike or an alloy gravel bike. I have a Swagman platform 2-bike rack but its heavy and not ideal for a carbon frame. They seem similar in price and function. Can you enlighten me, and perhaps explain why one would be a better fit than the other for my needs? Thanks.

Hey Tim, this is a really great question as the RockyMounts HighNoon part # RKY87RR and the Monorail part # RKY10007 are both very similar. To the point I almost don't see why they have both available at first glance.

But anyway the Monorail has a shorter max wheelbase at 48 inch compared to HighNoon which is 52 inch. The Monorail also sits about 4 inches closer to the vehicle at 12 inches compared to 16.

The Highnoon weighs 29 lb and the MonoRail 25 lbs.

Hey Tim, how did things turn out with the bike rack for your Miata? Did the weight difference between the HighNoon and Monorail make one a better fit for your carbon and gravel bikes? Your feedback could help others choosing between these two racks.
