Revelate Designs Joey Downtube Bag

The Joey is designed to mount on the underside of your downtube, which is typically clear of standard bottle cage mounts on the top of the downtube. However, if you have a bottle cage mounted on the underside of your frame, you will likely need to remove it to accommodate this bag.

It is very secure. The bag uses a compression-molded foam panel that conforms to the frame tubing and silicone-coated straps that grip tightly to prevent sliding or swaying, even on technical terrain.

Yes, the roll-top closure is specifically designed for easy access while the bag is mounted. You can unroll the top to retrieve items without needing to detach the bag from the frame.

It is fully waterproof. The bag features welded construction, which eliminates seams where water could seep in, ensuring your gear stays dry even when riding through puddles or heavy rain.

Because of its location, it is best for dense, heavier items that you don't need to access constantly, such as a spare tube, multi-tool, tire sealant, or a lightweight rain jacket. Keeping heavier items low on the frame also helps maintain a lower center of gravity for better bike handling.
