"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 and you have what we feel is the perfect endurance geo for all sized riders. The reason for this is that we wanted the 48 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.
