Lampre-ISD team mechanics were preparing new road machines for their riders prior to the start of this year's Tour de France. Wilier Triestina have only released limited information on the new Cento 1 SR so far but it's a significant change from the current Cento 1.
Unlike recent debuts from Scott and Trek, the Cento 1 SR doesn't aim to be a full-blown aero bike, instead featuring Kamm Tail shaping only in the fork blades and seatmast, according to Wilier Triestina. Adding in Wilier Triestina's recent launch of the ultra-light Zero 7, we expect the new SR to focus more on stiffness while still maintaining good weight and comfort metrics. This means the 'SR' designation could well stand for 'Super Rigido'.
Tube shapes are dramatically different from the existing Cento 1 throughout the new bike. We've seen squared-off profiles instead of the old Cento 1's mostly round forms, plus enormous asymmetrical chain stays, an ultra-wide BB386 Evo bottom bracket shell with press-fit cups, and notably wide and flat seat stays.

The stout carbon fiber fork is built with a tapered 1 1/8-to-1 1/4" steerer tube and the crown is neatly blended into the down tube for a clean and integrated look. Topping the seat mast is a carbon fiber Ritchey SuperLogic one-bolt head although other team bikes we've seen are fitted with a Wilier-branded head with a Selle Italia Monolink-compatible clamp.
Cable routing is fully internal and it's cleverly swappable for mechanical or electronic transmissions. In mechanical trim, the removable access panel atop the down tube should make it easier to feed cables through the down tube, and barrel adjusters are built in. Out back, the entire driveside rear dropout is replaceable, not just the hanger, and a battery mount is included on the underside of the down tube, towards the bottom bracket.

There's no word from Wilier Triestina on claimed weight or more specific technical features or design philosophies, but we expect complete information no later than the Eurobike trade show in August. So far, Wilier Triestina have only announced that the new frameset will cost US$3,999 or US$5,599 with Campagnolo Chorus. Other Campagnolo, Shimano and SRAM build kits are pending and there will be a choice of six colors – hopefully, these will include the Lampre-ISD team's brilliant neon hue.
