Racing Bolt-On Top Tube Pack
Best stable storage for competitive cyclists and long distance riders.
Engineered for the demands of ultra-distance competition and gravel racing, this storage solution provides a secure, stable way to carry essentials directly on your frame. The construction utilizes an ultralight, waterproof laminate that keeps contents dry during inclement weather. A standout feature is the magnetic flip-top opening, which allows for one-handed, rapid access to electronics or nutrition while riding. The design includes a protected cable port for charging devices on the move and closed-cell foam padding to safeguard sensitive items from vibrations on rough terrain. High-contrast reflective elements are integrated to improve visibility in low-light conditions.

Know before you buy
Yes, this is a bolt-on bag designed specifically for bikes with top tube mounting bosses. It will not attach securely to frames that lack these integrated bolt holes.
The magnetic flip-top is designed to stay closed during standard riding conditions, including gravel and rough roads. However, it is intended for quick access, so it does not offer the same level of security as a zippered closure for high-speed, extremely technical descents.
Yes, the bag features an integrated cable port that allows you to run a charging cable from a power bank inside the bag to your head unit or phone mounted on the handlebars.
The bag is constructed from a highly water-resistant laminate material that will keep your gear dry during rain showers and road spray. While it offers excellent protection, the magnetic closure is not a hermetic seal, so it should not be submerged in water.
Because this bag bolts directly to the frame, it eliminates the swaying and strap-rubbing common with velcro-style bags. The base includes protective padding, but we always recommend applying a small piece of protective frame tape to your top tube before installation to prevent any potential scuffing from vibration.
