Look 2007+ model year bottle cage - about 24g. Has a very low guard rail which allows front or even sharply angled almost side loading - great for small compact frames, even with large (California Springs DuoFLow 25 oz.) bottles on the seat tube (51 cm "S" Look 585 Ultra with 6 cm slope). I have about 10000 km use on the down tube cage and about 5000 km active use (filled bottle) on the seat tube. I haven't ejected a bottle yet, despite a fair bit of riding on rough roads, including descents, although that does not include any racing down 10% cobbled descents. The bottle removal force required is so much smaller than other alloy or carbon cages I've used that it took me a couple of rides to get used to that and not slam my hand into the bottom of the top tube when removing the bottle from the downtube cage - i.e., I was initially using too much force when removing the bottle, i.e., launching my hand into the top tube, when instead a gentle pull was sufficient - not hard to control, just different than what I'd been used to the last 30 years.
And yes, I'd use the Look cages on any brand bike. I use Time pedals on a Look frame - call the brands don't match police on me.
I still haven't dropped a bottle or broken or worn out a cage. As far as I know, these cages haven't changed since 2007, other than choice of colors.
