Even so subtle a change as new shoes can affect your cockpit setup, as a thicker or thinner sole means your pedal force is being applied from a slightly different angle. For cyclists who tailor their fit for each individual discipline and event, the adjustability and carbon construction expertise that ENVE builds in to the Twin Bolt Seatpost means it's strong and light enough for road and trail, easy to install, and intuitive to adjust via the titular Twin Link hardware. The Twin Link mechanism itself comprises two bolts that govern the movement of two wedges, which are twin peaks of adjustability that lock your saddle in place with a 0 to 27 degree range of tilt. The mechanism doesn't require tortured angling with a wrench to reach under the saddle where Allen keys fear to tread. Rather, the bolts are on either side of the clamp, sitting well below the saddle rails so you can adjust them with your preferred tool. For kit this nice not to mention to protect carbon rails we recommend the reliable restraint of a torque wrench.
