Picking the right bracket

Each bag comes with one bracket. You can see pictures of the bracket styles below: 

Choose your bracket with care!


In general, the High bracket is the most versatile and easiest to use. All you need is 80mm of exposed, round seat post. The High bracket keeps the bag well away from your wheel and your legs too. If you don’t know which bracket to use, choose the High bracket.  



The Low bracket holds the bag lower and closer to the seat post. This looks a bit neater on some bikes, but it needs much more care to ensure the bag doesn’t touch your rear wheel or your legs. Of these, avoiding the rear wheel is the most important. If your bag touches a moving tyre, it will be destroyed. 

Below are some indicative dimensions for using the low bracket with different sizes of bags. These dimensions are a guide only – your bike, and your legs, may vary. If in doubt, choose the high bracket! 

Minimum exposed seat post (from frame to saddle rails):

All sizes: 150mm

Minimum vertical distance from top of tyre to saddle rails:

  • Small bag: 190mm
  • Medium bag: 270mm
  • Large bag: 330mm
Front bracket

You can also select a Front bracket. This fitting goes on the handlebar, allowing you to mount a bag up front. If you use drop handlebars, check the width of your bars with care. The Small bag fits most drop bars. The Medium bag fits wider bars. If you use straight bars, you can use a Large bag upfront – a good option for bikepackers. By default, the front bracket comes with fittings for standard diameter bars.
If you have oversize bars, add a note to your order, and we will send you the appropriate fittings.
