Rogue OSO Magnetic Barbell Collars 2.0

Buy Now · $65.00

The Rogue OSO Magnetic Barbell Collars 2.0 take Rogue’s exclusive-branded OSO clamp — machined from 6061 billet aircraft-grade aluminum with a lever lock/unlock mechanism and a rubberized interior lining — and add four high-strength magnets, pressed (not glued) into machined pockets on each face. The magnets let the collars stick directly to a rack upright or rig crossmember between sets instead of getting tossed on the floor, the main practical difference from Rogue’s standard, non-magnetic OSO Barbell Collars 2.0. Each collar clamps onto a standard 50mm Olympic bar sleeve.

Owner reviews on Rogue’s own site are consistently positive: buyers report a tight, secure lock that holds through dropped reps, with the magnetic storage called out repeatedly as a genuine convenience. Independent coverage is thinner and more mixed — YouTube reviewers found the collar takes a moment to learn (a hidden third, fully-open lever position makes sliding it onto the sleeve much easier) and wished the magnets ran along all four segments instead of two, and Garage Gym Reviews’ buying guide likes the magnetic feature but has “trouble recommending” it over the cheaper standard OSO collars at $15 more per pair.

What is a Collar?

What barbell collars are

Collars (clips) lock the plates onto a barbell’s sleeves so they can’t slide or rattle off — a safety essential, especially for pressing and Olympic lifts. The common types: cheap spring clips, quick lock-jaw / quick-release collars (the everyday favorite — fast and secure), and competition collars (precision-weighted, 2.5 kg each, for calibrated meets).

What to look for

A secure clamp that won’t creep under drops or high reps, quick on-and-off operation, and a fit for your bar’s sleeve diameter (standard Olympic is 50 mm). For most home gyms, a pair of lock-jaw-style collars is the right balance of speed, grip, and price.

4.5/5 · 10 GymRadar reviews

Reviews by source

Expert 4.47/5 10 reviews
Youtube 4.0/5 2 reviews Both gathered YouTube reviews (Gear Mashers, Home Gym Chris) recommend the collars for their tight, secure hold and genuinely convenient magnetic rack storage, but each flags a real caveat: Gear Mashers found the magnets weaker than expected and packaging flimsy, while Home Gym Chris initially struggled to fit the collar until discovering the hidden fully-open lever position and wished the magnets covered all four segments instead of two.

The Rogue OSO Magnetic Barbell Collars 2.0 deliver the same drop-tested, lever-lock clamp as Rogue’s standard OSO Barbell Collars 2.0, plus four pressed-in magnets that let you stick them to a rack upright instead of leaving them on the floor between sets. The standout dimension is functionality once you learn the collar’s hidden third, fully-open lever position — owners report a tight, secure hold with genuinely convenient magnetic storage. The weakest is value: Garage Gym Reviews’ buying guide likes the magnet feature but has “trouble recommending” the $15 premium over the plain OSO collars, and one reviewer found the magnets weaker than expected and only on two of the four segments. A solid, well-built collar, but the magnetic upgrade is a nice-to-have rather than a clear must-buy over its cheaper sibling.

  • +Functionality: locks down tight with no plate movement, even on dropped reps, once the hidden fully-open lever position is used to slide it onto the sleeve (YouTube: Home Gym Chris)
  • +Build quality: 6061 billet aircraft-grade aluminum construction with a rubberized interior lining that protects the bar (manufacturer)
  • +Functionality: magnets let the collar stick directly to a rack upright or rig crossmember for storage between sets, freeing up floor space (manufacturer; YouTube: Home Gym Chris)
  • +Durability: owners report the collars holding up as "pretty much indestructible" after switching from cracked plastic collars (manufacturer, on-site customer review)
  • +Versatility: fits any standard 50mm Olympic bar sleeve and works with both bumper and competition-style steel plates (manufacturer; YouTube: Home Gym Chris)
  • Value: Garage Gym Reviews' buying guide has "trouble recommending" the $15 premium over Rogue's standard, non-magnetic OSO collars
  • Functionality: the magnets were weaker than one reviewer anticipated and could slide down slightly rather than holding firm (YouTube: Gear Mashers)
  • Functionality: magnets only sit on two of the collar's four segments; a reviewer wished for magnetic strips on all four (YouTube: Home Gym Chris)
  • Functionality: the collar's three-position lever isn't obvious at first — some buyers' negative reviews trace to not finding the fully-open position needed to slide it onto the sleeve (YouTube: Home Gym Chris)
