Description
Product Description
Keep small ride essentials close to hand with this compact 0.8-litre top tube bag. Its TPU-coated 600D polyester shell and high-frequency welded construction help protect the contents in wet weather, while the magnetic flap provides quick one-handed access. A slim profile leaves space around the knees, and the bag can be secured with the supplied straps or suitable frame mounting points.
Key Features
Weather-Ready Construction
TPU-coated 600D polyester, welded seams and an overlapping flap help shield everyday essentials from rain.
Magnetic Quick Access
Built-in magnets hold the flap closed while allowing fast one-handed opening during a ride.
Slim Riding Profile
The streamlined shape sits close to the top tube to reduce contact with the knees while pedalling.
Compact 0.8L Storage
Carry a phone, keys, small tools and other essentials without adding a bulky bag to the bike.
Two Mounting Methods
Use the three adjustable straps, or fit the bag to a compatible frame with suitable mounting points.
