Protect your cables, rip your descents. Ships with harness, bolt-on bar (for 31.8 mm), Voile straps, and helicopter tape.

The Barjam is a bikepacking harness designed to excel on the most technical singletrack descents. The mission behind the Barjam is to have your bikepacking rig ride like it does without the gear. Focus on ripping your descent, not on keeping your bags attached to your bike.

Availability: Available on backorder


The Barjam is making waves as the lightest, most secure bikepacking harness system that protects your brake, shifter, and dropper lines.  A major design feature includes a bolt-on extension bar to protect your cables no matter how hard your crank down on the Voile straps (an advantage over foam spacers). Rather then using brackets to extend your drybag forwards, the Barjam extends your drybag out and downwards, pinning it to the most stable connection possible – the frame of your bike. And when it comes to straps, nothing beats the reliability and death-grip of Voile®.

Harness system includes:


  • Bolt-on extension bar – for 31.8 mm handlebars
  • Two Voile® straps
  • Harness made out of 1000d Cordura or abrasion resistant X-Pac to protect your dry bag from abrasion
  • Helicopter tape to protect your head-tube from scuffs.


Design Advantages:

  • Doesn’t block light from bar mounted lights
  • Protects cables
  • Use a dry bag you already own.
  • Allows space for your hands up high on drop bars
  • Race ready weight
  • Voile straps stay in place when open. Allows easy dry bag mounting

Weight: 220 g


Recommended Set-up

  • MTB (Full suspension, Hardtail, Rigid mountain bikes): Run the Voile Straps underneath the crown of your fork to pin the dry bag to your frame.
  • Gravel: If there is minimal clearance to run the Voile straps under the fork crown use the harness head-tube strap to secure the drybag.
