Starting with a wide and consistent stack and reach range, we set out to design a frame that could handle on or off road conditions while maintaining a comfortable ride. As you start to review the geo chart you will noticed we have 3 different fork offsets, BB drops and rear center measurements. Add size specific tubing and 2 different sized rear triangles on our carbon models and you have what we feel is the perfect adventure geo for all sized riders. The reason for this is that we wanted the 44 and 61 to fit the rider correctly and make the geo changes needed to provide the perfect ride.
SIZE SPECIFIC FRAME DESIGN
Size Specific Design (SSD) is the Jamis design philosophy and technique used to create the best possible riding bike for each size rider. Rather than limiting frame size variations to just different length top, seat and head tubes lengths, we take an all-inclusive look at each frame’s total configuration. Every SSD frame will also feature size-specific BB drop, rear center, fork offset/trail and SST technology.
ECO Fork 12mm Thru-Axle
Enhanced Compliance Offset (ECO) fork blades are swept forward several millimeters to provide extra vertical compliance for a more comfortable and controlled ride without any compromise in lateral stiffness. This is possible in part due to the ECO’s reinforcing rib on the inside of the fork legs. The integration of a 12mm thru-axle into our fork maintains all of the characteristics of our ECO design while adding the thru-axle benefits of increased front-end stiffness and further reduced weight. Win-win.
142 x 12mm Thru-Axle
Securing the rear wheel to the frame by threading it into the rear dropouts is not only safer, it’s stiffer. Increasing the rear axle diameter from 10mm to 12mm provides a stable platform for the disc braking forces and allows us to tune the rear seat stays for more compliance/comfort. You will appreciate this on your long days. The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The 142mm hub dropouts provide a self-centering feature for the rear wheel for faster, easier installation.
To make life easier we have repositioned each mount externally in a variety of easy-to-use locations. With a wide collection of fork and frame mounts you can now choose to mount fenders, rear carrier, low-rider front carrier (or two cages for water bottles/ storage) and three front triangle water bottles. This will open up the options wherever and whenever you chose to ride. Bad weather, commuting, trekking, touring – anything is possible.
DROPPER POST READY
Just in case you want to continue to push the boundaries, we added cable routing capability for a 27.2mm dropper post.
