This paper outlines the design of a slopestyle mountain bicycle for Norco Performance Bikes®.
The design intent was a full-suspension, single speed, chain and belt drive (Gates Carbon Drive®) compatible bike using the preferred frame geometry of Norco® Team Rider Sam Dueck.
Our final design was a Faux bar layout with a concentric bottom bracket and 4″ of rear wheel travel.
We also designed 4 separate rockerarms to link the rear shock to the seat stay, each with a unique leverage ratio curve. Through analytical (MATLAB) and physical testing, we concluded that the Regressive 18% rockerarms would provide the ideal suspension characteristics for our design.
