PALLADIO is the seatpost that solves the adjustment problem. PALLADIO lets you set the saddle very precisely to within a half-degree of rotation and lock it down securely at exactly the right angle. You can adjust the saddle"s fore-and-aft setting in the certainty that this won"t compromise saddle angle. The key is the 3T-patented DiffLock adjusting mechanism, which ensures theres no interaction between clamp bolts and saddle support. The bolts dont need to be torqued down hard to achieve a secure fixing. Even if the bolts were to shake loose, the post cant let the saddle tip the rider violently off. Light, strong and stable, PALLADIO is a technical breakthrough offering a practical solution to a longstanding issue. Note: PALLADIO fits only saddles with industry-standard 7 mm dia round-section rails. Do not use this seatpost with saddles with oval rails, or rails in carbon-fiber composites.
