Apidura Aero Bolt-On Top Module

A completely strapless, aero-optimised long top tube pack that integrates seamlessly on your bike to increase carry capacity for long, fast days in the saddle.

The Aero Bolt-On Top Tube Module is a performance-oriented solution for competitive gravel racers who need to carry a bit more on their bikes, while maintaining a clean, secure fit.

The module can be run in isolation or combined with the Aero Frame Module, to create a complete watt-saving system that also increases carry capacity.

For years we’ve helped riders go further, now we’re helping them to go faster. Learn how.
