Compact And Aerodynamic
The slim design sits neatly on the top tube to minimise wind drag. Its shape avoids interference with pedalling, making it suitable for road, gravel and endurance riding.
Secure Strap Mounting
Nylon straps attach cleanly to the top tube and head tube. The scratch free design protects frame finishes and keeps the bag stable over rough surfaces.
Bolt On Mounting Option
Two holes in the base of the bag allow direct mounting to compatible top tubes. This provides a cleaner, more secure fit and removes the need for straps on frames designed for bolt on bags.
Durable PU Leather Build
The PU leather material provides a tough, weather resistant outer shell. The single compartment offers simple, reliable storage for nutrition and small items.
Frame Protection Advice
Topeak recommends using protective film or foam on contact areas. Dirt, sand or incorrect packing may cause frame finishes to dull or scratch over time.
