Boutique Italian bike maker Wilier Triestina has given a refresh to its popular carbon fiber Cento 1 SR roadster, scrapping the integrated seatmast in part because it was hurting sales. The permanence of making that cut was just too hard for consumers to wrap their heads around.

In its place is a traditional seatpost, albeit one that maintains the kamm-tail shape, which is claimed to enhance aero efficiency. The new seatpost was developed in collaboration with Ritchie, and this is the bike of choice for most of the UnitedHealthcare pro cycling team. In fact, over the past year, five riders have piloted this bike to U.S. national championship titles.

MSRP: $5500

This flagship rig comes stock with a full Shimano Dura-Ace mechanical drivetrain and Shimano RS81 wheels (not pictured), making it a truly raceable bike; weekend warrior gran fondo types ought look elsewhere.

Cable routing is fully internal and convertible to electronic systems should you decide to upgrade. It also has a slickly integrated fork that’s designed to improve handling, especially when diving in and out of corners. MSRP is $5500 or $3500 for fork, frame and seatpost.

    Great bike, have been on one since it’s debut in the Fall of 2012. My only word of advice to potential buyers is to steer clear of the fluo-yellow paint scheme. Mine has faded horribly to where the front fork is almost white. A frame in this price range should have better paint / pigments and UV clear coats to protect against fading. I’ve pestered Wilier USA about it numerous times and was referred to a bicycle frame painter to respray the frame at my cost. YMMV!

    I also own a 2013 Cento1SR. My question is this backward compatible? In other words can the integrated seat post on my 2013 be cut very low and this new seatpost fit into the old seat mast?
