Why choose it

The A-B Twister GSB X7 is more than a bag—it’s an extension of your ride. The AVS back system promotes airflow, reducing sweat on warm climbs, while the sternum and waist straps stabilize the load on rough terrain. Toss in a hydration bladder (sold separately) and you have a self-contained adventure pack that moves with you. The integrated rain cover ensures sudden showers don’t soak your gear, and the reflective accents keep you visible to traffic after dark.

Ideal use cases

• Daily cycling commutes
• Mountain biking and trail rides
• Short hiking trips
• Outdoor fitness activities

Good to know

This backpack does not include a water bladder. Pair it with any standard 2-litre reservoir for race day or long rides. The helmet holder is removable, so you can stow it when not needed. Cleaning is easy with a damp cloth; allow it to air dry. The fabric is durable 420D nylon ripstop, and the zippers ensure smooth operation.
