Technical advantages
- Minimum weight, maximum capacity: 98 g (without reinforcement) / 148 g (complete) for 2.8 L – energy saving and more dynamic cycling over long distances.
- Double waterproof access: 2 main zipped pockets (waterproof zip) to separate food/tools/electronics.
- Integrated organization: 2 interior pockets + key hook to secure small items.
- Weather resistance and easy maintenance: double-sided coated technical fabric, HF welds; rain protection and express cleaning.
- Connectivity and safety: covered outlet for hydration cable/hose; large reflective elements for visibility.
Compatibility
Universal mounting with pre-installed Velcro straps. Designed to fit under the top tube without blocking access to bottle cages on most road, gravel, and mountain bike frames. Note: requires sufficient clearance under the top tube; on some full-suspension mountain bikes, the suspension/shock absorber design may limit installation.

CYKL Team Advice
Distribute the weight: place heavy tools on the lower right side of the compartment to lower the center of gravity; and your power bank and external battery on the opposite side for balance. Pair it with a top tube bag for instant access and a saddlebag for your gear—it's the ideal setup for maintaining performance on our titanium frames. Use the included protective film on the contact points to preserve the finish.
