The waterproof zipper and splash-proof rating ensure your valuables stay dry in light rain or when passing through puddles. With three adjustable straps, it installs in seconds without tools and fits a wide range of frame geometries.

Ideal use cases

• Daily commuting: store phone, wallet, keys, and a small snack.
• Gravel and adventure rides: keep tools and spare tubes within easy reach.
• Road cycling: carry energy gels and a mini pump without a bulky saddle bag.
• Urban errands: secure your essentials while locking up the bike.

Good to know

The B67 frame bag is designed for universal fit, but it's always wise to check your frame's top tube length and head tube angle. The bag's compact 1-liter capacity is ideal for minimal carry, and the reflective logo adds visibility in low light. For best results, ensure the straps are tightened evenly to prevent movement on rough terrain.
