Stylus 0 Ltd Stealth Stylus is a fresh new take on the 2-bolt seatpost. The transition from the pillar to the saddle clamp assembly is a finned, rearward swoosh suggestive in shape of the classic one-bolt posts of yore. But the clamp bolts are deployed to either side of the saddle-support cradle, conferring greater stability and easier adjustment. Stylus–0 models place the seat clamp assembly in line with the seatpost for zero setback. Many athletes seeking outright speed favor this more forward position on the bike. Some frame designers are also specifying a slacker seat tube so riders can set their bike up with an inline post, which is lighter than a setback post. Top model Stylus–0 Ltd is a monocoque in high-modulus carbon-fiber, finished in UD matt Black with 3T glossy graphics.Note: Standard DiffLock seat clamp fits only saddles with 7-mm ø round-section rails. Saddles with oval rails require oval-rail clamp caps.
