Revel Bikes Rascal

CBF™ focuses on designing around the Center of Curvature (CC) and balancing that with the Instant Center (IC). Until now, most suspension systems have focused solely on the IC. CBF points the chainline and drive forces directly into the IC throughout 100-percent of the travel by balancing the CC over the chainring, resulting in maximum pedaling efficiency, regardless of where you are in the travel, what terrain you are on or what kind of power you’re putting down. All the power you put into the pedals propels you one direction–forward—allowing the suspension to do its job completely independent of drivetrain and braking forces, and making the sag setting much less important. When we first rode the largely-unknown CBF system, we knew it was something special, and we knew we could make the best riding carbon mountain bikes using this magical formula.
