Topeak FastFuel Bolt-On Top Tube bag Black

This bag is a compact top-tube storage that’s ready for your rides — whether you’re road cycling, gravel grinding, or bikepacking. This aerodynamic bolt-on top tube bag keeps snacks, tools, and essentials right within reach without interfering with your pedaling position.

• Bolt-On or Strap Mount: Designed to bolt directly to bikes with top tube water bottle bosses or attach securely with scratch-free straps for versatile compatibility.
• Quick Access Storage: Single main compartment with a full-length zipper gives you fast access to energy bars, gels, keys, or tools while on the go.
• Lightweight & Low-Profile: Weighs approximately 70 g (2.47 oz) and measures roughly 18.7 × 8.2 × 4 cm (7.4″ × 3.2″ × 1.6″) — big enough for essentials but slim enough to stay out of the way.
• Durable Materials: Constructed from a mix of 500D polyester, PU leather, TPE, and engineering-grade polymer for long-lasting use and resistance to wear.
• Cable Port: Clever opening for routing charging cables — great for powering devices like phones or GPS units while riding.
• Secure Fit: Fits top tubes Ø35 – 75 mm and head tubes Ø30 – 50 mm, so it works on a wide variety of frames.
