Jeff K.wrote a review of Blackburn Clutch Carbon Side Entry Cage on April 25, 2019
Familiarity: I've put it through the wringer
A bit pricey but the only bottle cage that did what I needed it to do, and did it well. A bit of a small front triangle on my frame made (almost) impossible to find a way to mount two bottle cages with 24oz bottles and my TopTube Bag. These can mount really low on the frame and are thin enough to get close together. They are also the only side pull cage I've tried that allows you to put the bottles in directly from the side and pivot up into place.
