BarJam Brackets & Carbon Bar 2.0

$140.00

The Barjam bracket and carbon fiber bar assembly only. This does not include the harness and voile straps.

The BarJam is a lightweight, exceptionally stable bikepacking harness that protects your brake, shifter, and dropper cables. The 2.0 version of this harness increased the strength of the brackets to an ultimate load of 728 lbf! (without breaking, brackets rotated on handlebar instead). Designed to excel on rough singletrack the machined 6061 aluminum bolt-on brackets extend your drybag out and downwards, past your cables. Voile straps are used for a reliable and slip-free way to secure your dry bag against the carbon fiber bar.

Locally machined 6061 aluminum bracket options for both 31.8 and 35.0 mm handlebar diameters.

Choose between locally machined 6061 aluminum brackets for both 31.8 and 35.0 mm handlebar diameters. Use 25" Voile straps for dry bags less than 9 liters, or 32" Voile straps for larger dry bags. Pair the BarJam with the Horton Front Pouch for maximum carrying capacity. To purchase the harness for Jones H-bars or Surly Moloko bars see our Loop Bar Harness version here.

Product does not include the bicycle handlebar, the photo shows the brackets mounted to a handlebar for context only.

Complete Rockgeist Barjam Mounting Instructions

The Barjam harness is a stable and versatile harness that works with any bike from road to full suspension bikes. The main mounting difference is how the rubber Voile straps and center webbing strap connect to the bike. Please see the illustrations below for the three options that best fits your fork and frame style.

Please be sure to order the correct clamp diameter for your handlebar (this is the same diameter that your stem clamps). 35 mm diameters bars are most commonly found on newer full suspension or hard tail bikes.
