ULAC TOP TUBE BAG PHONE CASE TB10 - BLACK
The ULAC Trekking Verve Urban (often identified by the TB10 model code) is a hybrid top tube bag that integrates a dedicated, touchscreen-compatible phone case into a 1.3L storage compartment. It is designed for riders who need their GPS or notifications visible while keeping tools, snacks, and power banks protected from the elements.
This "2-in-1" design is particularly popular with commuters and bikepackers because it eliminates the need for a separate handlebar phone mount, keeping your cockpit clean and aerodynamic.
Key Features
Touchscreen Compatible Window: The top of the bag features a clear, high-sensitivity TPU window that allows you to operate your phone (including maps and calls) without removing it from the case.
Dual-Zip 1.3L Compartment: Offers enough space for daily essentials like keys, a wallet, and a spare tube. The dual-zipper design provides easy access to the main cavity.
Power Bank Ready: Includes an internal mesh pocket specifically designed to hold a power bank, with space to run a cable directly to your phone while riding.
Water-Resistant Construction: Built with waterproof fabrics and weather-resistant zippers to protect your electronics from rain, road spray, and sweat.
Versatile Mounting: Features a "bolt-on" ready base for bikes with top tube bosses, as well as three adjustable Velcro straps for universal fitment on almost any frame.

✅ Why This IS For You
Navigation Users: If you frequently use your phone for GPS but don't want a bulky handlebar mount, the integrated top-down view is a streamlined solution.
Endurance & Tech Riders: The dedicated power bank compartment makes this an excellent choice for long rides where you need to keep your phone or GPS unit charged on the move.
Commuters: The 1.3L capacity is the "Goldilocks" size—large enough for your phone, keys, and a multi-tool, but slim enough to avoid knee rub while pedaling.
❌ Why This May NOT be for you
Oversized Phones: While it fits most standard smartphones, extremely large "Max" or "Ultra" models with bulky protective cases may be a tight fit for the window dimensions.
Hardcore MTB Trails: On very aggressive, bumpy terrain, a top tube bag with a phone on top can occasionally shift; a dedicated handlebar mount typically offers more stability for high-impact riding.
Minimalist Roadies: If you only carry a single gel and a credit card, the 0.9L Trekking version is lighter and lower profile.
BFC Pro Tip
If you are using the bolt-on method, we recommend placing a small strip of electrical tape or a rubber washer between the bag and the frame. This prevents the bag from vibrating against the top tube, which can occasionally cause "paint rub" over thousands of miles. Also, remember to tuck your charging cable neatly into the internal mesh pocket to keep the interior organized!
