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_25 models set the clamp center 25 mm behind the centerline of the seatpost, for riders who prefer to sit further back on the bike. Stylus_25 Pro is the value model of the range, fabricated in aluminum alloy with a shot-peened, black-anodized finish and the white 3T Pro stripe.
