Details

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).

          "The bag works very well and the claimed waterproofness is effective. you could keep valuables in there and slip it easily off and on if leaving the bike out of sight. Floppy bag syndrome is a thing of the past with the A.S.S. system too "- UK Gravel Collective

          As the final part of the 76 Projects A.S.S. system, it's well-executed and well-priced. The ability to do entirely away with paint-damaging straps and get a more stable bag that can be easily removed is a winner. The fact that they have made it look and function this well is a bonus. -Offroad.cc

          Being able to slide your loaded top tube bag on and off in a few seconds is brilliant for convenience and security. There’s no worry about bag flop, wobble or paint scratching either. -Bikeperfect

          We hate it went a product has to be junked when a part can't be replaced. If spares aren't listed then message us -> and we'll see if we can help.

          Great way to fix the column

          The top tube and column are firmly fixed, giving you a great sense of stability when turning the steering wheel. Since the bag does not move, you can open and close the zipper smoothly.

          Perfect solution for AXS dropper users

          As a AXS dropper and Redshift seat post user on my MTB and gravel bike respectively I have been looking for a practical storage solution. The Piggy on bike storage ticks all the right boxes.

          Sturdy, neat, practical, great desgin

          Does everything it claims and looks great on the bike. Fit my large format phone (S21) in a hefty case just fine. Great for the bikepacking trip I bought it for. Good place to keep money/cards/phone snacks/battery pack. It could still be improved, the stem spacer doesn't fit great and the collar that snaps to it needs to guided on when you re-mount it. This could be made a single action with some further design development.

          The quality of the bag is premium. The installation was easy. Delivery was quick. However, bare in mind that the bag is a bit long-and if you'll use it for commuting, at the lights stops you'll sit on it. Still, this is not an inconvenience for me, and I will order the slider and spacer to use it on both my bikes. Thanks

          Love that A.S.S.

          Takes all.of a couple of minutes to set up and remove a headset spacer to fit the clip ring. Slides on and off an absolute treat and has enough room for most of my rides. I like the elastic strap which holds my phone against the side of the bag and the mesh pocket which is just the right size for my multi-tool. Looks great, too.
