No Straps, No Top Tube Bosses Required

Now with updated 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 (standard 1/8" steerer, click here for additional spacers to suit Giant, Canyon and Specialized future shock).
  • Extra bike side sliders and clips available for fast swapping between bikes, see here.
  • 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

Waterproof, welded 600D fabric with TPU backing a DWR treatment
50mm wide x 110mm tall x 220mm long (approximately 1L).

      If you have a Specialized bike with a Future Shock you MUST buy this!

      Extremely secure and finely engineered bag and mounting system. The custom headset spacer for the Future Shock is amazing. As you can see in the photos, the installation is super clean and secure. I would recommend a layer of thin foam in the bottom of the bag if you carry anything that could rattle.

      Testing it out on the Crux.

      Testing period. So far it's looking good. I will follow up after BWR Cedar City.
      Looking forward to using it at Unbound 2024.

      Nice bag, letdown by poor zipper

      This is a very nice bag with a bad zipper. The bag looks great, is pretty water resistant and durable.
      and of course the mounting system is great. However the zipper when new was hard to open. After a few long gravel rides grit got in the zipper making it unusable. I have cleaned the zipper numerous times and even tried waxing it, but it is just too hard to unzip. So now I have a useless bag.

      Very good system.

      Would be 5 stars if owners of multiple bicycles could add on extra spacers and adhesive mounts at the time of initial purchase for as many bikes that the bag may be used on.

      Hi Jeff. We now have spare bike side sliders, spacers and pads in the spares section.
