Lezyne Flow bottle cage review

Finding a bottle cage that works well with a variety of bottle shapes can be difficult. Although in theory all cages and bottles should have the same diameter, in practice some bottle/bottle cage combinations give a more secure fit than others.

This isn’t such a problem on smooth roads, but on bumpy tarmac and particularly off-road a poor match between cage and bottle can result in the bottle jumping out.

We’ve recently tested the new Kinesis Tripster AT. It came equipped with three Lezyne Flow cages, including one under the down tube. Testing the bike over a variety of increasingly rough surfaces, the Lezyne Flow cages held a variety of different bottles securely without any of them working loose.

This is probably down to the Lezyne Flow cage’s design: there's an inward bend to the top on either side. The standard designs only have one catch at the top – or none at all. The Flow's design balances the forces holding the bottle in place but still lets you get your bottle out swiftly and easily.

The Lezyne Flow cage is made of fibre-reinforced plastic, so it should be durable. At 48 grams it’s a bit heavier than some other cages, but a pair still won’t unduly encumber your lightweight bicycle.

There’s also an HP version of the Lezyne Flow with different graphics and a side mount for fixing a high-pressure pump using the supplied Velcro straps. If you have a small frame which makes fitting a bottle difficult, Lezyne also sells a side-access SL version in left or right bottle access variants. Lezyne currently offers the Flow cage in white or black, although for 2018 there will be additional colour options.
