N-1C - frame + pinion c-line c1.12 gearbox
Now that you have chosen the Pinion gearbox, we can customise some details. Each Olsen Frame can be changed by you the customer.
The "base geometry" design is a culmination of all the years designing 29inch wheel geometry, but has scope for change. The "swing-plates" hold the gearbox on - however they also allow the geometry to be adjusted for LONG or SHORT travel forks. The "swing-plates" change the chainstay length and bottom bracket drop. These are several options that we will guide you through with drawings.
