The Cannondale Topstone Carbon is Cannondale’s first gravel bike, and the first gravel bike on the market with a rear suspension system. Add in clearance for 700 x 40c or 650 x 47b tires, stubby 415 mm chainstays, and mounting points galore, and the 2020 Cannondale Topstone Carbon Ultegra RX 2 gravel bike is made for the sportier side of traveling off the beaten path.
Cannondale’s coup d’etat in entering the gravel bike market with a carbon bike is it’s Kingpin rear suspension system. The American brand claims itself to have the first rear suspension gravel bike on the market with a simple thru-axle pivot that locks the left and right seatstays together. This pivot floats between two bumpers in the seattube that allow for a total 30 mm travel. They pair this to their signature OutFront geometry, which Cannondale claims “Keeps the steering light and agile, while positioning the wheel further in front of the rider for stability and confidence on rougher stuff.” Add in tight 415 mm chainstays and dropped rear seatstays to further improve compliance, and you have the makings of a zippy, comfortable gravel bike.
Other features within the Cannondale Topstone Carbon include clearance for a 700 x 40c tire or a 650 x 47b tire, both with room to spare. You’ll find multi-position bottle cage mount on the downtube, and bottle top tube, seat tube, and under the down tube. You’ll also find fender mounts, mid-fork mounts, and internal routing for a 27.2 mm dropper post.
The 2020 Cannondale Topstone Carbon Ultegra RX 2 gravel bike is based around a full carbon frame and fork, and is paired to a Shimano Ultegra R8000 with a 46/30t Cannondale 1 crank and 11-34t cassette, ideal for loose, steep climbs. This is paired to a WTB KOM Light i23 TCS/Formula hub wheelset. A Cannondale carbon seatpost, WTB Riddler 700 x 37c tires, Cannondale alloy handlebar and stem, and the Cannondale integrated wheel sensor complete the bike. Topstone Carbon is available in five sizes (XS-XL).
