Cannondale Contain Welded QR Bag

The bag uses a T-bracket that attaches directly to your saddle rails. You simply twist the bracket to lock it into place, allowing you to quickly remove the bag when you need to secure your bike or swap it between different bicycles.

Yes, the bag is constructed from waterproof nylon and features sealed, waterproof zippers. It is designed to protect your essentials from road spray and light rain, though it is not intended to be fully submerged.

This size is ideal for the essentials. You can comfortably fit a spare tube, a multi-tool, a tire lever, and a CO2 inflator or a small patch kit. It is compact enough to stay out of the way while pedaling.

Yes, the bag includes a dedicated rubberized fabric section with a light clip or strap, making it easy to mount a rear blinker for better visibility in low-light conditions.

It is designed to fit standard saddle rails. If you have a specialized saddle with non-standard rails or a very unique shape, the T-bracket may not seat correctly, but it works with the vast majority of road, gravel, and mountain bike saddles.
