This is a great product; I recommend fully reading Rogue's Description and Reviews to make sure you understand what options will work best for you when ordering. As such, I wanted to provide some detailed feedback on my purchase. I have a Rogue Monster Lite Wall Mount rack in Rogue red. One thing that attracted me to these J-Cups is the built-in protection to ensure your rack does not chip or dent since I paid extra for the fancy paint job. I owned the J-Cup and J-Cup 1" sandwich versions before Rogue added rack protection. I used Plastidip previously to help prevent wear and tear with moderate success. These are very solid; the stainless steel pin makes them slide effortlessly when repositioning. Like other reviewers, I had one that fit perfectly snug and one that sat a little loose on the rack. I opened a ticket with Rogue Support, and they immediately sent out a plastic replacement kit with three size options that replace the rearmost guide support and some shims to use if needed. This fixed the problem immediately. (Some feedback to Rogue: putting little size markers on the rear of the plastic components would have made identifying the sizes a little easier.) I purchased the steel rollers; again, as other reviewers have stated, the trade-off is either cleaning the plastic off your bar or having marks on your bar. Not spinning the bar while racked is just not something you will ever do. I have a Rogue red Ohio bar; I plan on buying a stainless steel bar to use with these J-Cups and use the red one for deadlifts, etc. In the meantime, I bought a roll of APT's 3" UHMW (Ultra-high Molecular Weight) Polyethylene Tape from Amazon. It doesn't look too bad, and it resists the abrasion when the bar rolls in the cups. The way it sits in the cups, you only need to cover 3" to protect your bar when sliding from side to side. The portion where the bar rests on these cups is a little shallower than what I was used to with the 1" sandwich version, and the bar does automatically reseat itself in the forward position, which I really like. Overall, it's a great product; the shim fix from Rogue should get everyone back on board with this being a 5-star product.

After reviewing all the online reviews, I began to realize that most popular ones were 1-2+ years ago. These hit that sweet spot of features, quality and price. Glad I did because these are awesome. Game changer from your standard J-cups. The rollers really do improve the functionality of your rack and impact every exercise using a barbell. If you are looking, go for it. You will not be disappointed.

If you are worried about them being loose, don’t. They fit really tight. Puts the bar in the perfect spot every time.

These are a wonderful product. They replaced my standard J cups and fit much more snugly on my older RML-3 rack. So snug that removing them requires some effort. I’ll be buying another set to keep at my incline height. I don’t lift heavy enough to really need them, but there is something unexplainably nice about shifting the weight back and forth before a lift. I also like the knurled wear pattern that develops on the composite roller after use. i also have the camber blocks for these for the CB-4 bar but have found that I use my mono lift more for squats with that bar than J cups.

Started with squating using a bar with low knurl. I was and am concerned with the longevity of the rollers. I wanted to see what happens so I started with the light knurl. Squated 3x5 267.5. The rollers have definite marks but only time will tell. I use a wider grip than I should and the cups make it a bit harder to get into my same grip. I am now using a bit narrower of a grip and that's OK because that was my goal anyways. The cups are tight on my Monster Light rack, but they still can move a bit when adjusting the bar, not a big deal. The bar now sits more forward and is another thing to get used to but I found it to be an easy adjustment. The convenience of the roller outweighs any inconvenience the cup has. Next I moved to the bench press and switched to my power bar with heavy knurl. This is a game changer. The bar being in the front of the cup is a small but impactful difference. The roller has more marks but only time will tell how long they last. These are worth it. Hopefully the roller last 12 months before I have to buy replacements.

I purchased the upgraded version of the Ghost Rollers mainly because I wanted the stainless steel shoulder bolts that go through and support the roller. The shoulder bolts offer an extremely smooth operation of the roller. I also opted for the composite rollers to protect the knurling on my stainless Ohio Power Bar. Definitely a beautiful product.

I was worried I wouldn't be able to use these with my strap safeties but they do fit. The bottom of the roller j cup sits about an inch lower than standard monster lite j cups but that worked in my situation. The bar is at the same height in both pictures.

Ordered 1/14 and received today! No customization. I really never write and have ordered lots from Rogue but this has to be some of the best packaging I have ever seen. Love the included packing sheet with the check offs for quality control and signature. Fit perfectly in the rack and easy to move up and down with one hand but heavy and overbuilt. First workout was a pleasure. Very pleased with this kind of quality. Very fair price in my opinion.
