What Our Gearhead(R) Experts Are Saying: "I like this bag for long gravel and endurance rides when I want quick access without knee rub. It mounts securely on everything from road bikes to mountain bikes, and the elastic cord system doesn't scuff paint. The low profile stays out of the way, and the zipper is easy to use one-handed while riding." When we're settling into long miles and steady cadence, the Ultra Top Tube Bag 0. 7L becomes our go-to storage for the essentials we need within reach. POC designed this bag with a clean, minimal profile that disappears between our knees while still giving us space for nutrition, electronics, and small valuables. It's ideal for endurance rides, bikepacking days, and everyday training when pockets just aren't enough. Built from durable X-Pac fabric, the bag sheds road spray and light rain while keeping contents organized with internal mesh pockets. Thoughtful details like the cable port for electronics and subtle reflective hits make it easy to integrate into a modern cockpit setup. Secure, simple, and purpose-built, it's a small addition that makes a big difference on long rides.
