- SOSalvador O R.Verified BuyerRated 5 out of 5 stars2 months agoJ-Cup review
The J-Cups are amazing. The bar is easily adjustable because of the rolling pins. I 100% recommend this Product. The only issue I have is the rear locking pin hole doesn’t match my cage holes.. Unfortunately I can’t use them. Other than that overall amazing product.
Bells of Steel Canada2 months agoThank you so much for the great review, we're so glad you enjoyed your new equipment! Unfortunately some brands' hole spacing doesn't match some of our attachments. Let the Gainz begin, BoS Crew - JNJason N.Verified BuyerRated 5 out of 5 stars4 months agoGreat product!
They do exactly what they’re meant to do. I’m so happy I bought them, and they didn’t cost the same price as my entire squat rack.
- DDuckyVerified BuyerRated 4 out of 5 stars1 year agoGreat entry level roller j-cups
Confirmed rear locking pin. A lot beefer than what I expected. Rollers spin nicely, but these are brand new, I don't know how long these will hold up. The rear locking pin is a huge plus, and I hope these are on sale separately. The pin is on there real tight and I could not hand loosen them. They also came in dined up.....which was sad. I gave this a 4 stars cause I wished it had the UHMW on top and front of the roller, in case I hit the front of the rollers while racking. Also, if it had some bracing on the sides, it probably hold 1K in weight (BOS confirmed these are like the Hydras, 600 lb limit). I don't lift that, but it probably would last a lot longer.
Overall these are probably going to be the best entry level rollers j-cups on the market. I'm happy I got them and differently would recommend. I hope your locking pins aren't dined up like mines.
Bells of Steel CanadaHi There, Thank you so much for reviewing our manticore roller j cups. We are so happy to hear you have been overall pleased with these. We apologies for any damage occurred during shipping and if you have any issues please don't hesitate to reach out to us. We wish you the very best. Sincerely, Marcus & the BoS team - MSMichael S.Rated 5 out of 5 stars3 years agoNeed Roller J hooks for Titan X2 rack
Needed or more so wanted, roller j hooks for my titan X2 rack. These are close in size that I took a gamble and bought them. Not disappointed at all. These seem really durable. The rollers are very smooth. They make centering the bar so much easier now. I mostly use a 32 mm rogue squat bar and anything over 225 the bar would not shift to either side very easily. They save time and most importantly energy when re-centering the bar. At 300+, I would have to pick the bar up and shift it over on the stock j hooks, NOT ANYMORE. These make life so much simpler. Roller j hooks should just come stock with all racks from everyone. SO to get these to fit the X2 rack, I used a 2 part epoxy and glued - 1/8" thick UHMW plastic on the insides of the j hooks. Its not the prettiest looking but I was short on time and I don't care about how they look on the inside...I have attached photos for a reference.
On a side note, B.O.S. contacted me before they shipped this out as to as ask if these will fit my rack cause there was no record of me owning a B.O.S. rack. thought it was strange but ok. Delayed shipping by about 2 days just to confirm these would fit. I knew the pin would fit an just had to do some math on the plastic inserts.
Bells of Steel CanadaWe're excited you love your Roller J Cups! We're even more excited you were able to "adjust" them to make them fit for you. We like to confirm with customers that don't have our racks to make sure the attachment they purchased fits their rack prior to shipping. Thanks for the review, now back to the gainz! Erica and the B.o.S Crew! - ENEric N.Verified BuyerRated 5 out of 5 stars3 years agoAmazing
Can't get this anywhere else let alone for the price. Great quality, use it on my lever arms to simulate a assisted lifted off without a partner in benching. Only suggestion is to add uhmw plastic. Great company to buy from
