Jon Jwrote a review of RockyMounts SplitRail 2-Bike Hitch Rack on July 17, 2016
Familiarity: I've used it several times
RockyMounts brings a solid contender to the hitch mounted rack field. I've previously owned the Yakima HoldUp, and have used a buddy's Kuat NV quite a bit. The Splitrail is on par with both of those. Though having a claimed weight of 44lbs for the 2in receiver option, the rack feels lighter, and more balanced than the HoldUp which claims to be 39lbs.
It took me 30 minutes to install the Splitrail, and assembly is very straightforward and easy with the included hex wrenches. The hitch's fir system creates a very stable interface, with no wobble, but can be in issue if you're moving the rack from one car to another regularly. The rear handle for adjusting the position of the rack is also a strong point. The rack has ample clearance for 29 and 27+ tires. Though RockyMounts doesn't recommend it, I was bale to fit my fatbike with 4.8 tires onto the rack with a ski strap, but do so at my own peril.
The locking system is a weak point in my opinion compared to other offering. A cable extends from the arms, and a metal chuck locks into the end of the cable creating a loop. No rack's included lock/cable is very substantial, they're all there to keep people honest, but the Splitrail's system limits where you can loop the cable. If I were leaving bikes on the rack during an extended period of time, I'd use a thicker cable looped through the hitch like I have with my HoldUp.
Overall the Splitrail is a great rack, that's easy to use, and will get you and your bike to and from the trail with ease.
