Vinny Maurowrote a review of Lezyne Flow SL Cage on March 28, 2017
Familiarity: I've used it once or twice and have initial impressions
After using the fancier Arundel carbon side loader cages for a while I am totally sold on side-loading, but for my new bike I figured I'd try to pinch some pennies and get this thing instead for a fraction of the price.
At first glance putting the bottle in, it honestly didn't look like it had the same quality of fit/grip on my bottle as the Arundel did. However... after a handful of test rides I have had zero issues with the bottle moving around and it is equally easy to load and unload.
The Arundel is still a super nice piece for sure, and adds some nice blind to your bike, but this Lezyne is an awesome alternative if you've tapped yourself out on the rest of your build.
