Cyclite Top Tube Bag / 03 1.1L

The CYCLITE Top Tube Bag / 03 is the third generation of the German brand’s most popular and sophisticated top tube bag. Its wide flap with magnetic closure allows immediate access to the contents without taking your hands off the handlebars, whilst its exclusive LiteGrid-RN200T3 material gives it weather resistance and a lightness (weighing just 124 g) rarely combined at this level of finish.

This new version brings several major improvements compared to the previous generation. The front strap has been completely redesigned: it is now replaceable and extendable, making it compatible with integrated cockpits – a real highlight for modern aero bikes. The lightly padded base protects your smartphone and electronic devices even on stony paths, and the reinforced sides with a slightly reduced width prevent any contact with your thighs when riding out of the saddle. A zipped inner pocket completes the organisation, and a protected cable or hose passage is integrated so as not to restrict installation on the bike.

The Top Tube Bag / 03 is available in two colours (light grey and black) and forms part of the CYCLITE range alongside the Nano and Large versions. It can be secured either using the supplied Velcro straps or by screwing directly onto the frame (M5x12 screws included) for frames fitted with threaded inserts (the most stable and cleanest solution). Awarded ‘Best Choice 2025’ by Tour, My Bike, radsport-news.com and GRAVEL Review magazines, it is one of the highest-rated top tube bags on the market.

Compatibility:

The CYCLITE Top Tube Bag / 03 is compatible with all bikes fitted with a top tube (road bike, gravel, hybrid, bikepacking). It mounts behind the stem or in front of the seatpost. Both positions are possible if you wish to use two panniers simultaneously. For frames fitted with threaded inserts (M5), the pannier can be screwed on directly without straps. The extendable front strap also makes it compatible with integrated handlebars (one-piece handlebar and stem).

FAQ

1. Is the bag really accessible whilst riding, even at high speeds?

Yes, that is precisely the strength of the Top Tube Bag / 03. The magnetic closure opens and closes with one hand, without looking. The flap opening provides an immediate view of the contents — ideal for grabbing an energy bar or your phone whilst riding hard.

2. Do your thighs rub against the bag during intense pedalling?

No. CYCLITE has designed the 03 version with reinforced sides and a slightly reduced width compared to the previous generation, specifically to prevent any contact with the legs, even during a sporty ride or when riding out of the saddle.

3. Is it compatible with an integrated cockpit (one-piece handlebar and stem)?

Yes. The front strap of the Top Tube Bag / 03 has been redesigned to be extendable, making it compatible with integrated handlebars, which are often wider than standard stems. It is also replaceable should it wear out.

4. Can I carry my smartphone without worrying about knocks?

Yes. The base of the bag is lightly padded to absorb vibrations and protect electronic devices, even on rough terrain or unpaved tracks. The weather-resistant material also provides protection in the event of rain.

5. What is the difference between the Medium (03), Nano and Large versions?

The CYCLITE range offers three sizes: the Nano for minimal bulk (maps, gels, small accessories), the Medium / 03 version with a 1.1 L capacity and the signature magnetic system, and the Large version for long rides requiring more capacity. The 03 version is the most versatile and the most award-winning of the three.
