Compact Triangular Frame Bag — fits any bicycle frame, fast and secure installation Why you need it Keeps essential items (phone, power bank, repair kit) within easy reach so you can ride focused and prepared. Slim, top-tube placement reduces wind resistance and stays out of the way of your knees and legs. Water-repellent construction with zippered closure protects contents from light rain and road spray. Key features and benefits Universal fit: three adjustable Velcro straps allow quick mounting on most bike frames and ensure a snug fit on the top tube. Triangular, slim profile: ultra-thin housing sits close to the frame to minimize drag and prevent pedal-stroke interference.

Zippered, water-repellent material: protects belongings from moisture during normal riding conditions; not designed for prolonged heavy rain or submersion. Spacious interior with side zip: roomy main compartment fits a mobile phone, power bank, repair tools, mini pump, cycling gloves and other essentials; side zipper provides easy access without removing the bag. Practical use scenarios Commuting: store your phone, keys, and a power bank for navigation and on-the-go charging without adding bulk to your commute. Weekend rides and group tours: carry a small repair kit, multi-tool, and mini pump for quick fixes so you can get back on the road faster. Training rides: keep energy gels, a phone, or lightweight gloves handy and accessible without disrupting cadence or leg movement.
