Roomy, compact storage - with 1L capacity and 23 x 11 x 5cm dimensions
Internal volume equates to about one litre, sized to accept a smartphone, small multi-tool, mini pump and a folded inner tube. An elastic cord on one side gives quick-access space for snacks or slim items.
Pack essential repair kit and daily items without adding bulk to the top tube. Quick-access elastic keeps frequently used items within easy reach while riding.
Secure attachment - thanks to three adjustable hook-and-loop fasteners
Three strap points clamp the pack to the top tube and head tube junction, allowing tension to be adjusted for different frame shapes. Close contact with the frame reduces movement during rough terrain.
Stable fit avoids bag rotation or bouncing on off-road sections. Confident handling remains unchanged when tools are carried inside.
Improved visibility at night - with fully reflective side panels
Reflective material covers the side panels so that light from vehicle headlights bounces back toward observers. High-visibility surfaces are placed where they catch lateral road lighting.
Increased side visibility helps make riders more noticeable after dark. Suitable for commuting routes and quieter roads where being seen matters most.
