The elegance of beauty, form, and function?
Claiming innovations in the areas of continuously-variable transmissions, two-stroke engines, and bicycle suspension, Raer Design’s portfolio is certainly a broad one. First conceived in 1991, the firm’s Directly Connected Suspension was born of the desire to avoid what is being called ‘pitch’. The distinctive crossed shocks are each connected primarily to one wheel… and secondarily to the other. The intent is to raise the front end when the rear is compressed and vice versa, keeping the bike and rider level on varying terrain. Beyond running counter to this explanation, a statement that rear braking compresses the front suspension is of some concern, given that brake jack is something many have worked very hard to avoid.
Originally envisioned for motocross use, Directly Connected Suspension is also said to have the (unintended) effect of minimising pedal bob – a good thing given the latest version’s high rear suspension pivot – improving pedaling efficiency as a result.
For those looking for more detail, the Raer’s discussion on the theory behind the Directly Connected Suspension design is fascinating.
