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 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 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 26L in volume and can be rolled down to more than half of that. Yeah, 26 liters! You’ll believe it when you see it.
- 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.
