Author A-R290 Energy Bag Top Tube Bicycle Frame Bag, 0.7L, Black

The Author A-R290 Energy Bag rethinks on-bike storage for riders who want essentials within a thumb’s reach without the bulk of a full frame pack. Unlike oversized top tube bags that can interfere with pedalling or cable routing, this compact 0.7-litre design sits low and narrow, keeping gels, bars, a phone, or keys exactly where you need them. The universal Velcro strap system mounts to virtually any top tube and steerer tube combination in seconds, while the 600D polyester shell shrugs off spray, mud, and daily abuse. A single zippered main compartment with internal padding protects your cargo, and the integrated cable port lets you charge a phone or power a light on the go. Reflective Author branding adds a subtle safety boost for early-morning or dusk rides.

Highlights

• Compact 0.7-litre top tube bag for energy gels, bars, phone, and small essentials
• Universal fit: three Velcro straps (two top tube, one steerer tube) secure to most bicycles
• Water-resistant 600D polyester construction with internal padding for impact protection
• Single zippered main compartment keeps contents secure and quickly accessible
• Integrated cable port allows charging devices while riding
• Reflective Author logo enhances visibility in low light
• Low-profile design avoids knee contact and cable interference

In daily use

Mounting takes less than a minute: wrap the two top tube straps around the frame, loop the steerer strap around the fork or head tube, and cinch them tight. The bag stays put over rough gravel, potholes, and hard efforts out of the saddle. The main zipper opens wide for easy access with one hand, even with gloves on. Inside, the padded compartment prevents your phone from rattling against tools or keys. The cable port is positioned at the front, so a charging cable can run cleanly to a handlebar-mounted device without kinking. When you need to remove the bag for cleaning or security, just undo the straps—no tools required.
