Rogue IWF KG Competition Collars


Rogue IWF KG Competition Collars

This variation of our Competition KG Barbell Collar is approved for official use by the International Weightlifting Federation, meeting the IWF’s strict spec and calibration standards (-0/+10 gram tolerance). Each collar includes engraved Rogue branding and an IWF sticker.

Unmatched for precision, stability, and strength, Rogue’s KG Competition Collars are formed through an investment casting and CNC machining process that ensures maximum integrity and a flawless surface; aided by a hard chrome finish. A unique ball lever mechanism allows for a secure hold and easy adjustments, and at a weight of 2.5 KG each, the collars can also serve as useful “change plates” in their own right.

Rated 5 out of 5 by from ROGUE BLING!! I have always wanted these types of collars and they don't dissapoint so far! I have metal plates that rattle a bunch and paint could easily chip if the plates weren't sandwiched tight together. No matter how I tried with EVERY POSSIBLE type of collar there was always rattling. Enter the solution! I place a 1/4lb solid rubber micro weight between the collar and the plates. I turn the dial and it compresses the rubber a little so it acts like a lock washer. No rattle, no adjustment between sets ...problem solved! 3 things I learned. 1. The tightening mechanism is an arc on the inside of the collar that presses down on the bar evenly. It's not just a screw sticking through so no worries about scratching the collar. 2. Drop of oil in the threads makes it spin much more smoothly. 3. When doing curls and other similar lifts the arm on the collar will bounce around so...rattle gone but now need a solution for the new sound. Blue loctite, magnet,rubber band, Velcro? Not sure but still happy so far. This is seriously overkill for amateur lifting folk but all the $ saved on gas, vacations and such for a year paid for my new home gym so this was just a serious "want" but you only live once!

Rated 5 out of 5 by from Almost Perfect Occasionally the tightening rod gets a little cumbersome. But that is probably just a matter of getting used to it. I have not used heavy collars like these for about 15 years.

Rated 5 out of 5 by from Luxury Item I got these for myself as a b'day present. They are serious overkill; gorgeous slick overkill. A total splurge, for no good reason but worth the price of admission because they're functional art that makes me feel good.

Rated 5 out of 5 by from Great weight and beauty of a piece. Strong hold. Love these IWF rogue barbell clamps. Great clamping force securely hold my bumper plates, iron/steel weights and change plates. Quick release and fast to clamp.

Rated 5 out of 5 by from Nice collars I bought them to go along with a Pyrros bar as a set. Nice collars - well manufactured, excellent finish, accurate weight, and they work as advertised. The added benefit of acting as calibrated 2.5kg plates is also quite nice. For day to day lifting, they are not as convenient as the Rogue/OSO style collars and are quite expensive.

Rated 5 out of 5 by from Solid product Expensive, but the 2.5kg calibration adds to the value. I’m getting older and pairing down my home gym to a few quality pieces of kit that I always use. Sold my bars and picked up a Pyrros bar with these collars - both are of the highest quality and a great value compared to the competition. The collars are cumbersome to use though, and for general WOD use I would recommend a set of the Rogue or OSO metal collars (plastic versions break).
