Frustrated with floppy bags, worn paintwork and cafe stop faff we sort to design as system this strapless quick release system for top tube bags/bento boxes/fuel pods. Works with most bag and bike combinations.

A.S.S. Slider

Replaces top tube straps

  • Bonds* to the top tube OR screws directly to bosses
  • Slide on/off quick-release - ideal for taking your valuables with you
  • 2 piece - 1 attaches to top tube, 1 attaches to bag
  • Works with bolt-on bags and others which can be easily converted**
  • No headtube strap required for small bags / bento boxes. Large bags may require use of the headtube strap or ASS Clip
  • Manufactured in-house using our Multi Jet Fusion industrial 3D printer and shot peened for surface toughness and quality.

    *Using the supplied custom cut VHB tape - successfully used on thousands of our ENDURO mounts

    ** Instruction on converting non-bolt-on bags can be found online, in our experience stiffer bags are better for conversions.

    A.S.S. Clip Instructions


    Do I need a Clip if I’m using the Slider?

    It really depends on the bag and what you’re putting in it. A Tri orientated bento box will likely not need the clip. A huge 1.5L top tube bags full of electronics will need a clip. Tall bags will likely need a clip, bags with little stiffening will likely need a clip.

    Great concept - well implemented

    I did not have any bolt-on points and a top-tube bag. The ASS Clip solution was good for me. Though I had some changes to my stackers on my steerer tube to allow the clip ring to sit at the right height and retain my current stem height. The Clip itself was straightforward to mount on my top tube bag. Of course, with just the clip I still have my top tube bag with a velcro strap around the top tube, but the clip stopped the shifting of the bag.

    Product is good but expensive

    It is a product that makes the bolt-on top tube bag easy to use and has a good degree of completion.
    But it is expensive.

    Quick and effective way to get a quick-release top tube bag without bento mounts

    Used top tube bags for years to keep insulin pump controller, quick carbs and other diabetes clutter close-to-hand but always a faff strapping bag on and removing when stopped at cafes etc. Looked at magnetically mounted bags in past but they relied on having bento-mounts on the frame. The ASS Clip & Slider work perfectly with an Apidura ‘Racing Bolt-on Top Tube Bag’ to give super-quick access to stuff that can also be added/removed from bike in literally seconds.

    Great Manbag solution

    Nicely thought out solution to quickly remove your top tube bag. I used it to adapt my Apidura bag and it works a treat for taking your valuables into the coffee shop especially if you don't tend to use jersey pockets. The 3M gave up after a year and couldn't get any more during lockdown but some heat shrink tape worked fine. Recommended 👍
