76 Projects A.S.S Top Tube Bag

No Straps, No Top Tube Bosses Required

Now with update hinged clip - for greater allowance between top tube and headtube angles. Optional to use bungee for extra security. For easier assembly the internal washers and nut have been replaces with a single strip.
Please note that the instructions and some photos do not reflect the changes.

A top tube bag with our A.S.S. Anti Strap System built-in. Whilst designing the standalone Anti Strap System we tried many top tube bags; some where super light, some were tough, some had huge capacity, but none had all the features we wanted in an everyday top tube bag. So we set about designing our own.

• Slide on/off quick-release - ideal for taking your valuables with you
• A.S.S. Slider bonds* to the top tube OR screws directly to bosses
• A.S.S. Clip Includes a special 10mm stem spacer 
• No interference with stem, no rubbing and high stability
• External stash pockets - Keep sticky used wrappers separate
• Internal mesh pocket
• Internal phone retainer - stops phones rattling around
• Cable port
• YKK Aquaguard Zip
• Extended side skirts conceal the A.S.S. Slider mechanism
