Rockbros A30 ROAD TO SKY opvouwbare bagagedragertas 15-30L grijs

Cyclists who commute through unpredictable weather or embark on multi-day tours need gear that adapts on the fly. The Rockbros A30 ROAD TO SKY rear rack bag expands from 15 to 30 litres, swallowing extra layers, groceries, or repair kits without weighing down the ride. Its grey 600D nylon shell shrugs off splashes, while reflective accents keep you visible after dusk.

Key specifications

• Expandable capacity: 15–30 litres via roll-top extension
• Waterproof 600D nylon with PU coating; IPX4 splash resistance
• Folded dimensions: 300 x 230 x 170 mm; expanded height: 340 mm
• Weight-optimised design with 8 kg max load capacity

Why choose it

Unlike rigid panniers, the A30 collapses when empty to reduce drag and bulk. The roll-top closure lets you adjust volume in seconds, and the waterproof fabric protects contents from rain and road spray. A detachable shoulder strap turns it into an off-bike carryall, ideal for mixed-mode commutes.

Ideal use cases

• Daily commuting: carries laptop, change of clothes, and lunch
• Weekend touring: expands for camping gear or extra clothing
• Grocery runs: secure, splash-proof transport for small loads
• Road cycling: streamlined folded profile for fast training rides

Good to know

The bag attaches securely to most rear racks without tools. For maximum stability, distribute weight evenly and ensure straps are tightened. The roll-top closure provides quick access and adjustable volume, while the detachable shoulder strap adds convenience when off the bike.
