I have both left and right-handed versions of these side load cages as well as the other front load offering. I'm using these on both my gravel and road bike. They're the best option I've found to date for securely holding my stainless Camelbak Podium bottles. They hold without rattling and without a death grip that keeps me from being able to drink while moving. The price is higher than most polymer cages but also much less than pricier full carbon fiber versions. These hit the sweet spot. Worth it IMO. Definitely recommend these.

This is a gem

Purchased a "left" hand version to sit on my seat post (and thus it is for my right hand)--needed this to replace the carbon fiber one from Specialized that broke. Once again I am less than impressed with Specialized items due to their low reliability--this one from ENVE is barely heavier and has withstood the abuse it gets on my gravel bike. For lightweight side-specific bottle cages, this one is the best I have seen so far.

I use a sideloader and have ZERO complaints!
