Bremmy Roller J Cups

Bremmy Roller J Cups

A slim design to mimic a sandwich J-cup but also have a roller that allows you to easily center the barbell before you lift. The roller is made of 2” UHMW that protects your bars and collars from damage. These have an elongated hole at the bottom that allows you to use any mag pin (not included) to secure it from swaying.

The quality of these are 100% S Tier. Bremmy does an amazing job with these. I use them every time I squat or bench. One of my favorite things about them is the diameter of roller he uses. It prevents any metal on metal contact between the barbell collars and the J cups or your rack. Quality welds, quality powder coat, quality packaging and a quality dude!

I believe these are the best rollers on the market. I personally build these. I also use the every single day for bench and squat. They make minor adjustments very easy while still feeling solid.

I don't own these yet, but they are on my wish list. Literally, they are on my Gym Radar wish list. Make one of those if you don't have one already. It's a great feature. I have played with these roller J-cups in Basement Brandon's Gym, Anand's Gym, and Coach Carp's Gym, and they are my favorite I've ever seen.

I've gone through every pair of roller j-cups there is and at a time was even making my own before they were commercially available. I have no issues saying the Bremmy ones are the best that have been made so far. Thin design, lots of UHMW protection, and they can secure via pin if wanted. The biggest drawback here is he only makes so many a month, so lead times may be long!
