SciCon is an Italian company it's only fitting that they make the sleek, minimal Phantom 230 Roller 2. 0 Saddlebag that you can still cram everything into. Part of their trick in making this possible is their new Roller 2 mounting system. If you recall the original Roller System now Roller 1, you start with a plastic cleat that secures to your seat rails with the twist of a knob. Then you install the bag by matching the cleat with the opening in the binding mount. And give it a 14 turn. The Roller 2 takes that same idea and adds two tire levers to the design. There's one mount for a tire lever outside the bag, and a mount for a tire lever inside the bag. To make sure the lever slots work, SciCon includes the levers. Building the two levers into the design frees up space in the bag, so you can fit more stuff in it. The bag itself has a mix of materials. The side panels are carbon fiber weave and the main panel is Cordura. A zipper runs three quarters of the way around the bag, giving you easy access to everything inside. The interior of the bag is open, a single cavity, with a hook and loop strap for compressing the bag. Reflective piping runs along the seam between the carbon fiber and Cordura panels. The SciCon Phantom 230 Roller 2. 0 Saddlebag measures 7x5. 5x12cm and has a volume of 230 cubic centimeters 14. 354 cubic inches.
