Ultimate Gear List Best Handlebar Bag Jumbo Jammer

We won the Best Large Handlebar Bag by Ultimate Gear List!

Jumbo Jammer Handlebar Bag for Bikepacking and Commuting

As Jumbo as Jumbo can be! This bag was designed with the casual cyclist in mind but also willing (and desiring) to get a little rowdy now and then. Don't let your gear keep you from exploring local single-track. "Rugged riding ahead? Bring it!" 

Jumbo Jammer Handlebar Bag

The Jumbo Jammer is a high volume, rackless, universal handlebar and saddlebag. This massive bag is the largest in our Jammer line and perfect for city commuting/road touring/dirt bike packing and casual beach rides - load it up with the essentials and have plenty of room for more gear. This bag was designed by cyclists for cyclists!

It is easy to use, fun to ride with, and a treat when you need it; forget your bike is loaded down with the help of the Jumbo Jammer! Lightweight, durable and weatherproof!

Jumbo Jammer Handlebar Bag

There are two external expanding front pockets with a flap lid. The lid has a 2" strip of 3M reflective and a blinky light loop directly above. This bag was made for either front (for dirt) or rear (for the road) use and will accommodate various bikes, handlebars, and different riding styles.

Jumbo Jammer Handlebar Bag

The closure straps (C.W.S.) were designed to give adjustable positions for the optimal weight to tension ratio. You can load this pup up and cinch it down to create a stiff and compact bag with minimal sway or sag when mounted appropriately.

Jumbo Jammer Handlebar Bag

The bag has an internal structure to give form and an internal stiffener which will not bend or break. We designed this bag to open up new options on how your gear is carried, don't be afraid to get creative and try different mounting techniques!

Jumbo Jammer Handlebar Bag

When fully expanded, the Jammer will reach up to 26L in volume and be rolled down to more than half of that. Yeah, 26 liters! You'll believe it when you see it.

When using this bag on the rear for road use, note that the bag mounts to the Saddle Loops. If your existing saddle does not have the Saddle Loops, please refer to our recent blog post. If you need extra hardware for mounting this bag to the rear, preview our additional hardware page here.

Use the 550 parachute cord loops at the top to attach with our Universal Shoulder Strap. Carry it off of the bike with ease and style!

Installation Guide* Ft. Rat as Rat!

*Please be mindful and avoid mounting the bag against cables and housing.
With this in mind, the Jammers may not be compatible with cantilever brakes.


  • Dimensions:
  • Materials:
  • Features:
  • Height: 8"- 19" 
    Width: 14"
    Depth: 6." 
    Weight: 2lbs

    Volume: 26L at max height with two rolls down for waterproofing. 11L at the minimum roll.

    Max load limit: 25lbs! Respect this bag, and it will continue to give for years to come.

    Minimum Front clearance required: 10" - 12" measured from the top of the handlebars to the top of the tire. If you have less than 12", keep the front pockets empty as they will likely rub the tire.

    Minimum Rear clearance required: 10" - 12" measured from saddle rail to the top of the tire. If you have less than 12", please keep the front pockets empty as they will likely rub the tire.

  • Our material selection is ever-expanding and made to fit the look of your bike! The exterior shell is made of 1000D Cordura, with a high denier, seam taped, Rip-Stop nylon liner. Nylon webbing and YKK buckles and hardware. 

  • The Jumbo Jammer includes additional hardware that is made to run parallel from the D-Rings (located at the top of the lid) to the handlebars. Use these straps to carry extra gear on top of your Jumbo Jammer.

    Additional Hardware Installation Guide: The best method for using this hardware is to attach the velcro bits to your handlebar with the female side of the buckle looped through. Then, loop the additional webbing around the D-Ring and back through the tri-bar adjuster.

    Other features include: 
    • Internal stiffeners for added stability
    • Dual Expanding Front Pockets
    • Front 3M Reflective
    • Blinky Light Loop
    • Adjustable Mounting Techniques
    • Internal Roll Top Stiffener
    • Seam taped liner for a fully weatherproof main pocket
    • Front or rear mount ability depending on road conditions and pack load. We suggest a light load for rear use. When mounted on the rear, the bag performs optimally for road use but can be used in the dirt if packed appropriately, i.e., heavy and bulky stuff at the bottom and cinched like hell! Use the Additional Hardware included along with the bag to secure it to the bars. Who needs five attachment points when you can create a 7 point attachment system!

"This product, like all of our products, is 100% vegan and crafted with the finest USA made materials and hardware. No animals were harmed during the making of this bag." - Ester Song, CEO
