I’m late reading the replies, but thank you very much!!
I take it bars specifically for olympic stuff are fairly flexible? for the whip?

I don’t think it’s a good idea.
If you load say 100kg, the impact of collision becomes concentrated in a very small surface area. I am no expert, but imo this would accelerate damage to the your plates. Especially if you only use 10kg (close enough to 25lbs) bumpers, they are quite thin.
You want as much surface area as possible to spread out the force.
As PBandy suggested, try to get fatter plates if you can.[/quote]
I agree with what dan said. The more load that hangs outside of the bumper plates (even if it’s a smaller diameter) then the more momentum is going to be generated when the bar hits the floor. What will happen is the bumper plate will stop but the weights outside will want to KEEP GOING DOWN. This will flex the bar and put enormous pressure on the bearings in the bar. For starters you need a proper bar with the correct needle thrust bearings that can take the impact on the floor, but I imagine that not using bumpers will damage these over time as well. Not all bars with rotating ends are suitable. If you have nylon or brass bushes instead of roller bearings then forget about dropping it.
I would get at least a pair of 20 or 25kg bumpers so that at the very least you could load some smaller plates in between this and the 10kg plates you already have. This would spread the surface area a bit and stop more of the flexion because the 10kg plate would be on the outside, but the smaller weights in the middle are still going to want to go down a bit, os it’s best to be safe and get enough bumper plates and a proper bar, you’ll only spend yor money once!

yes. i found this not so long ago:
(sales pitch for eleiko - but nice explanation of the different bars)
I deadlift with the women’s oly bar sometimes and it is a weird feeling… Because the bar is bendy the bar will start to move before the weight leaves the floor. Inefficient deadlift.
Weightlifters can ‘catch the bounce’ when the weight is heavy. There is a bit of a rebound where the weight hits the end of the give in the bar. Apparently you can time this to use the bounce to help you stand up the squat (clean).
The women’s bar is bouncier than the guys bar, apparently, too.
growing epidemic of obesity. lol.
bump for a question. So it obviously the general consensus on this thread is that one pair of bumper plates loaded on the bar is far to little for any appreciable weight. Anybody want to hazard a guess at a ratio? If I had a pair of 20kg and 10kg bumpers, so the bar would load to ~180lbs, could I load it to 200? 220? What about 2 pairs of 20kg and a 10kg, how heavy do you suppose that could be loaded?
I would recommend nothing more than a 35 lb plate outside the bumpers, but I’ve hear of others loading a couple of 25 lbers on each side. Personally, I don’t like anything more than 10 kg outside the bumpers (22 lbs) in iron without adding/changing to heavier bumpers. BUT, that’s me and I want my bar taken care of, not to mention the plates because they are expensive. I don’t want to buy them again!!
12 or 13 rims with tires. Have to search out optimum tire size or just get taller tires and stand on blocks to get correct height. Not perfect but works and if you are handy you can modify so it fits collar better.
