We’ve all been there. You want to carry a water bottle cage on your bike – only there’s nowhere to mount it. Rather than offering different cages for different mounting standards, Granite Design’s Aux cage allows you to do both.
Yup, that’s right. The Aux cage will mount to any standard water bottle bosses. It will also mount to any number of things thanks to the lateral slots, above the traditional mounting holes.
When purchased with the optional strap kit, the Aux Cage includes a silicone rubber pad that interlocks with the traditional mounting holes, and protects the frame from the cage while helping to hold it in place. Then, the silicone coated hook-and-loop straps allow you to cinch down tight – tight enough to hold a full bottle in place.
Kits include two sets of straps to fit tubing diameters from 27.2-70mm, which gives you a wide range of things to strap to.
The Aux Cage itself is made from a carbon fiber reinforced thermoplastic composite, with a side-loading design to better work with full suspension bikes. Checking in at just 23g for the cage with a matte finish, you can pick up the cage only for $20.99.
The strap kit with a cage is a bit more, at $27.99 for the set.
