Syncros offers a comprehensive range of on-bike storage solutions for hydration and tools for trail side repairs, and in the case of the iS Tailor Cage reviewed here, both simultaneously. This one caught our attention because of its super compact design, a highlight feature if you’re looking to mount your tools and water to the front triangle of a bicycle where space is at a premium.
The cage itself is ambidextrous, meaning you can mount it for easy access on the right or left hand side. It includes a bracket to mount a 16g CO2 canister, or a hand pump. And it houses a 19 function multi-tool. The great appeal is that, with all of those essential items living on your bike, it’s impossible to go riding without them. I mounted the Syncros iS Tailor Cage to my small Revel Rail this Spring time; here is how it fared.
Review: Syncros iS Tailor Cage
Given the multi-tool lives on the Syncros iS Tailor Cage, it’s important to take it out and dry it off after every ride to prevent rust. Obviously, I neglected to do this on more than a few occasions, and the result is shabby-looking, but still perfectly functional multi-tool. Before we get into the detail of the tool’s functions, let’s take a look at the versatility of the cage itself.
The first thing I noted was that the cage is pretty flexible. That helps you stuff the bottle into the cage when you’re in a hurry, and it means the cage is less likely to snap in a crash. It holds a regular water bottle securely, and I am happy to report no runaway bottles over the last 4 months of riding.
It can be mounted in two possible ways; angled off to either side to suit the handedness of the rider. Another thing to consider when mounting the cage is clearance, with respect to the trajectory of the shock and any rotating links as the rear wheel is pushed through the entirety of its travel.

The CO2 bracket is designed to hold a 16g CO2 canister. For MTB, it would ideally hold a 25g canister, to ensure proper inflation of high volume 29″ tires. The 16g option was fine for my 27.5″ x 2.4″ WTB Judge. The inflator head is good. It allows you to control the flow of CO2 into the tire, so you don’t have to dump it all at once. It also features a sliding plastic cover that protects the portion that attaches to the valve, keeping it clear of dirt.
