Ortlieb Extension Mounting Set

Yes, this extension set is not a standalone mount. It specifically requires the Ortlieb E164 lockable mounting hardware to function correctly on your bike.

This mounting set is designed specifically for compatibility with the Ortlieb Ultimate5 series of handlebar bags.

If you have unconventional handlebars—such as swept-back bars or specific aero setups—a standard mount might not provide enough clearance. This extension pushes the bag further forward, ensuring it doesn't interfere with your hand positions or brake levers.

By extending the bag further from the handlebars, you may notice a slight increase in leverage on the mount, especially if the bag is heavily loaded. It is best suited for standard gear loads to maintain stable handling.

While it is designed for unconventional setups, its primary purpose is to clear obstacles on flat or riser bars that prevent standard mounting. Depending on your specific drop bar geometry, it may or may not provide the necessary clearance, so check your cockpit space before purchasing.
