On Saturday Fabian Cancellara (Trek-Segafredo) won his third Strade Bianche aboard a curious unreleased Trek Domane bike that sports at least two new technologies.
Looking side-on at the bike, it appears Cancellara is riding the next generation of Trek’s endurance bike, the Domane. The original Domane was first revealed in 2012 and has remained largely unchanged since.
Designed to soak up the cobbles (or general bumps) the Domane’s main trick is the Isospeed pivot, which isolates the seat tube from the top tube. This allows the seat tube and connecting seat mast to act as long uninterrupted lever and greatly reduces vibrations and impacts when seated. It’s a technology that has since been rolled out into Trek’s Boone cyclocross range, the Procaliber hardtails and, most recently, the ultra-aero Madone 9 Series.
A split seat tube is most certainly new
It appears this new generation Domane continues with the Isospeed technology, but ups the comfort ante. The seat tube reveals a major change, moving from the previous round tube to what appears to be a split-tube design. This is reminiscent of the Canyon VCLS 2.0 seat post, where far greater vertical flex is given by creating a leaf spring of sorts.
