Our Middle Earth Jammer was built around the everyday commuter. From road bikes to gravel bikes, this bag was made to traverse. Use it as your go-to commuting bag, then take off to the mountains for a quick overnighter. Maxing out at 19L, this bag is more significant than it seems!

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 Jammer! Lightweight, durable and weatherproof!

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.
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. 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!
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!

Dimensions:
Height: 8"- 19."
Width: 12."
Depth: 6."
Weight: 1.5lbs
Volume: 19L at max height with two rolls down for weatherproofing/ 10L minimum volume.
Max load limit: 25lbs. Respect your 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", please keep the front pockets empty or filled with flat items as they will likely rub the tire.
Minimum Rear clearance required: 10" -12" - measured from the saddle rail to the top of the tire. If you have less than 12", please keep the front pockets empty or filled with flat items as they will likely rub the tire.

Additional Hardware Installation Guide: The best method for using this hardware is to attach the velcro bits to your handlebar with the buckle's female side looped through. Then, loop the additional webbing around the D-Ring and back through the tri-bar adjuster.
All of our Jammer Bags use a roll-top closure combined with dual vertical adjusting straps. We call this our C.W.S.: Closure Webbing System.
The C.W.S. creates a 4 point compression to keep the bag cinched tight and gives it the 4th mounting point (either around the handlebars or saddle rails), eliminating sway and sag. Remove the webbing strap from the d-rings and restring the webbing around the point of interest, then back to the bottom D-ring and up to the roll-top closure buckle.

Other features include:
• Internal hard liner for added stability
• Internal stiffener for added stability at handlebar/saddle mounting points
•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 - oh yeah!
• YKK Buckles and hardware
• Made in the USA Nylon Webbing, Velcro and Hardware
• 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!
