You can drop them without causing huge crators in the floor your standing on or damaging the weights.

I might be wrong, but when you approach your max on the on Olympic lifts, don't you drop the weights from the fully extended position?

Bumper are not just rubberized steel plates. Rubber coated steel plates or rubberized steel plates won't survive being dropped on a regular basis.

Bumper plates are designed to survive being dropped. The rubber is much thicker than just a coating and the hubs are sturdier and wider. Some bumbers are solid rubber, others like the Eleikos have a steel core but are still mostly rubber.

Also, steel plates come in a variety of non-standardized diameters, except for the 45 lb. plates which are all 450 mm in diameter. All bumper plates are 450 mm diameter, regardless of weight. In fact, a 45 lb. plates is really a re-worked 20kg plate in disguise. That's why they have such an odd dimensions - 45 pounds and 17 5/8" inches.

The advantage of bumpers is safety for the lifter and longevity for the equipment. A lifter who is hesitates to dump a bad lift because he's afraid of damage to the floor or the equipment is more likely to get hurt.

To illustrate Lincoln's point: A lot of CF WOD's involve 95 lbs. Cleans, C & J etc. Using iron, your coming off the floor alot lower with 2 25 lb plates on the bar; this throws off technique or forces you to go from the hang position.

I ran across someone selling 'Ivanko EZ carry urethane plates'. I'm not sure they are "Bumper plates", they are olympic size. Any feedback from anyone?

They are most definitely not bumper plates. They are urethane-coated steel plates. Ivanko makes some bumper plates and those ain't it. (And the Ivanko bumper plates aren't great bumpers, anyway.)

Yeah Mike, that was a good discussion thread. The only bumper from Ivanko I'd recommend is the 5kg bumper. Very, very useful size to have around and cheap compared to anyone else's 5kg bumper. http://ivanko.com/products/prd_text/OCB-5KG_popup.html

For all other sizes, get the RB Rubber composite style or if you've got disposable income get the Eleiko bumpers.

Talk to Scott Tully at BS Olympic Gym, he'll set you up.
