As Jumbo as Jumbo can be! This bag was designed with the casual cyclist in
mind but one that is 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!"

The Jammer bag is a unique high volume, rackless, universal handlebar/saddle
bag. This bag was designed with you in mind! This bag is perfect for city
commuting/road touring/dirt bike packing or 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
Jammer! Lightweight, durable and water resistant!

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 road) use and will accommodate a
variety of bikes, handle bars 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 really 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 fully expanded the Jammer will reach up to 29 L in volume and can be
rolled down to more than half of that. Yeah, 29 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 then
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

***Production Note*** Please be aware that these bags require a minimum of a 2
week lead time + appropriate shipping time. Be mindful that we are a small

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. That's right folks: seam taped = waterproof!

finest USA made materials and hardware. No animals were harmed during the
making of this bag.

Additional Info:
C.W.S.
The Jammer Bag uses 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 (as shown in the photos above) and
works to keep the bag cinched tight as well as giving it the 4th mounting point
(either around the handle bars or saddle rails) which then eliminates sway and
sag. Simply 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.

Jumbo Jammer Additional Hardware
As clutch as the Jumbo Jammer is, you may feel a little left out with larger
loads. The Jumbo Jammer Additional Hardware is made for running parallel from
the D-Rings located at the top of the lid and then connected to the handlebars.
Preview this 50 second video for tips on installing the hardware effectively.

Additional Hardware Installation Guide:
I've found that the best method for using this hardware is to attach the
velcro bits to your handle bar 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.

Front or rear mount ability depending on road conditions and pack load. We
suggest a light load for rear use. The bag performs optimally for road use but
can be used in the dirt if packed appropriately i.e. heavy stuff at the bottom
and cinched like hell!
