Zefal Z Adventure T1 Bolt Top-Tube Bag
The Zefal Z Adventure T1 Bolt Top-Tube Bag is a sleek, low-profile storage solution designed for riders who want easy access to essentials without compromising ride feel or bike aesthetics. Perfect for road, gravel and adventure bikes with top-tube mounting points, it keeps your gear secure, organised and protected from the elements.
With a 1-litre capacity, the T1 Bolt is ideal for carrying ride essentials like your phone, wallet, nutrition, tools, power bank or spare tube. Its 100% welded construction and waterproof zip ensure everything inside stays dry, even when the weather turns.
Unlike strap-on bags, this bolt-on design mounts directly to threaded top-tube bosses, creating a cleaner, more streamlined fit. Not only does this improve stability and handling, it also eliminates strap rub — helping protect your frame and paintwork on longer rides.
Inside, thoughtful organisation features like an internal mesh pocket and key hook keep smaller items easy to find. There’s also an integrated cable port, allowing you to discreetly run a charging cable for your GPS, phone or lights while keeping the bag neatly zipped and tidy.
Compact in size and carefully shaped to avoid knee contact, the Z Adventure T1 Bolt blends practicality with comfort — making it a great choice for commuting, endurance riding or bikepacking adventures where minimalism matters.
