PALLADIO is the seatpost that solves the adjustment problem. PALLADIO lets you set the saddle very precisely Â- to within a half-degree of rotation Â- 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 DiffLockÂTM adjusting mechanism, which ensures thereÂ"s no interaction between clamp bolts and saddle support. The bolts donÂ"t need to be torqued down hard to achieve a secure fixing. Even if the bolts were to shake loose, the post canÂ"t 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: Standard PALLADIO fits only saddles with 7-mm ? round-section rails. Saddles with oval rails require oval-rail end caps (available as a 3T accessory).
