Specialized Diverge Expert Carbon All-road Crusher

2015 Specialized Diverge Expert Carbon

No doubt, the latest all-road bikes are a gas. With them, you can connect Road A to Road B via that winding gravel road you’ve always longed to ride. You can ride the pavement until it ends. Or, you can haul around with the kids at the local singletrack. Versatility is a winning attribute in life and the new Specialized Diverge lineup is versatile in all the right ways.

When the new Diverge platform was being teased by the Specialized PR team, I initially pegged it as the new Roubaix. It looked the part and had many elements that led me in that direction. But, with the current Roubaix only on it’s second season, it didn’t make sense.

Then, the whole “gravel grinding” phenomenon hit me like a ton of bricks and I realized that this would be a new platform for all-road adventures — and so it is.

The geometry is unique with some shared elements to the Roubaix, like the seat tube and head tube angles. Aside from that, however, any geometry similarities are merely in the ballpark. Of particular note is a¬†bottom-bracket drop that’s 4mm lower than a comparable 56cm Roubaix. And a 1mm longer wheelbase, just for good measure.

Every bit of the Diverge is made to have fun and to get aggressive on any terrain of choice. It’s not so slack and stretched out to be “un-fun.” Check out the following overview from Specialized Bicycle Components University (SBCU) for more details.

The Diverge series has three flavors in a variety of build levels. The three carbon models feature the same FACT 10r carbon for the lightest, stiffest and smoothest ride. Then there’s a single Smartweld version and three standard aluminum models. All feature disc brakes, but only the carbon models feature thru-axles at both ends. Drivetrains and brakes are Shimano with FSA and Specialized stuff mixed in. For the best performance-for-the-money, I’ve pegged the Diverge Expert Carbon, at $4000.

Prior to launch, the crew from Deux North assembled a globe-trotting crew to ride 300 miles over the course of three days in and around Specialized’s Morgan Hill HQ. The results of this adventure can be seen in their Hunt 4 video below.

The Bottom Line

Riding any road, anytime has a ton of appeal. And, the Diverge Expert Carbon is a nicely-equipped bike that can hang on that Gran Fondo, while at the same time, it can hold its own on some sweet singletrack.
