The CYCLITE Top Tube Bag / 03 represents the third generation of the German brand's most accomplished top tube bag: only 124 grams for 1.1 liters of volume, an ultra-fast magnetic flap closure accessible with one hand while riding, and a high-frequency welded waterproof construction that withstands all weather conditions. Award-winning in international tests, it stands as the bikepacking reference for secure and immediately accessible transport of your snacks, tools, power bank, smartphone or any essential equipment during your gravel rides, ultradistance events or adventure raids.

Technical synthesis: record lightness and extreme robustness

The Top Tube Bag / 03 is based on the proprietary material LiteGrid-RN200T3, developed by CYCLITE: a 200 denier recycled nylon ripstop fabric combining two different thicknesses of fibers woven by special technique, then double coated TPU/PU3 and high-frequency welded. Result: a perfect symbiosis between extreme lightness (124 g with straps, 138 g in bolt-on), tear resistance, and total waterproofing without compromising ease of cleaning. The bag's bottom integrates light EVA padding that protects smartphone and electronics even on rough terrain, while the stiffened sides and reduced width (5 cm) eliminate any contact with thighs, including when out of the saddle or during hard efforts.

Revolutionary magnetic closure and instant access

• Magnetic flap with FIDLOCK buckle: one-handed opening and closing while riding, without zipper or complex gesture — ideal for grabbing an energy bar or tool without slowing down
• Large gaping opening: optimal visibility of contents and intuitive organization thanks to the elastic PA mesh inner zippered pocket
• Long grab loop: facilitates flap opening even with thick gloves or in difficult weather conditions
• Structural stability: reinforced sides prevent bag sagging, even when fully loaded, and guarantee a stable shape on rough trails

Optimized mounting: bolt-on or stretchy straps

The Top Tube Bag / 03 introduces a major evolution of the mounting system, acclaimed by users: the front strap is now stretchy, removable and replaceable, ensuring full compatibility with integrated cockpits (one-piece handlebar-stem), often wider than classic stems. The bag mounts in two ways of your choice:

• Hook-and-loop strap mounting: 3 straps supplied (including the stretchy front strap), quick tool-free installation, frame protection included via transparent adhesive film
• Bolt-on mounting (direct screwing): 2 M5×12 screws with O-rings included, ultra-stable and clean mounting — 2 mounting positions available to fit almost all frame geometries (minimum distance 7 cm between front screw hole and rear edge of head tube)
  • Mounting behind head tube (forward position)
  • Mounting in front of seat post (rear position)
  • Possibility to install two bags simultaneously (front + rear) to maximize carrying volume
• Protected cable/hose exit: waterproof passage on handlebar side for routing brake cables, housings or hoses without compromising waterproofing

High-performance bikepacking: volume, organization, versatility

• 1.1 liter capacity: ideal volume for long rides, lightweight bikepacking and ultradistance raids — sufficient storage for smartphone, powerbank, multi-tools, mini-pump, keys, light gloves, snacks and energy bars
• Elastic mesh inner zippered pocket: fine organization of small items (keys, cards, cables) and separation from main contents
• Reflective elements: increased safety in low-light conditions (night riding, dawn, dusk)
• Aerodynamic and slim profile: streamlined design that integrates harmoniously with modern bike lines (aero road, gravel, hybrid) without affecting handling or disturbing pedaling
• Universal compatibility: fits all bikes equipped with a top tube — road, gravel, cyclocross, hybrid, bikepacking — regardless of geometry (sloping, horizontal, compact)

Environmental commitment and responsible manufacturing

CYCLITE, brand founded in 2020 in Grassau in Upper Bavaria (Germany) by Christoph Kirsch and Max Bernsteiner, adopts a structured eco-responsible approach: bags are manufactured primarily from recycled nylon, the brand favors repairability and robustness to limit replacement, and donates 1% of its revenue to environmental associations through the 1% for the Planet program. Designed by experienced bikepackers for demanding cyclists, the Top Tube Bag / 03 embodies a clear philosophy: go further with lightweight, reliable, durable equipment designed in the Bavarian Alps.

Available variants

• Light Grey variant: EAN 2002000002731 (main reference supplied) — clean and discreet look that harmonizes with light frames and natural colors
• Black variant: available without communicated EAN — elegant all-black look, perfectly coordinated with the CYCLITE range (notably Frame Bag / 01 for a harmonious set)

CYCLITE ecosystem and range compatibility

The Top Tube Bag / 03 integrates into a complete range of CYCLITE ultralight bikepacking bags, including the Top Tube Bag Nano / 01 (0.6 L), the Top Tube Bag Large / 02 (2.2 L), as well as Frame Bags, Saddle Bags and Handlebar Bags. All bags are designed to combine harmoniously and offer a global carrying system weighing less than 1 kg for nearly 30 liters of total volume — one of the lightest bikepacking sets in the world.
