The Deda Zero1 Seatpost is built from 6061 aluminium alloy — a material that takes abuse without complaint, making it a reliable choice for riders who put their bikes through their paces day in, day out. At 350mm in length with a 20mm setback, it suits a wide range of rider positions without overcomplicating the fit equation. The two-bolt clamp head is where the Zero1 earns its keep. Both bolts are accessed from underneath the clamp, which makes saddle angle adjustments straightforward and precise — the kind of detail that matters when you're dialling in a position on the road rather than in a workshop. Available in 27.2mm and 31.6mm diameters, it covers the two most common seatpost standards.
