Cannondale Slate gravel bike prices and specs revealed (video)

New gravel bike has lefty suspension fork and 650b wheels

Pride of place at the recent Cycling Sports Group show in Wantage went to the new Slate. We've covered Cannondale's pre-launch videos of the Slate in previous posts. Shown in Army Green with a Shimano 105 drivetrain, the most radical feature is its Lefty Oliver carbon suspension fork, which has 30mm of travel.

The Slate also comes with 650b wheels, which are shod with Panaracer filetread 42mm tubeless tyres. Because of the larger tyre diameter, this results in an outside diameter for the wheel-tyre combination which is the same as for a standard 700c wheel shod with a 23mm tyre.

This means that the chainstays can be the same length as for a standard road bike, which Cannondale says results in agile and quick handling. The front-centre (the distance between the bottom bracket and the front axle) is extended relative to a standard road bike though, to give the bike more off-road stability and better handling over rougher surfaces.

Although suspension is a boon on the uneven surfaces for which the Slate is designed, it can be a disadvantage on smoother roads and when climbing as the up and down movement reduces pedalling efficiency, so there’s a lock-out on top of the fork for when it’s not needed.

The Slate’s aluminium frame comes with a BB30a bottom bracket, Cannondale’s Save Plus compliance zones built into the chainstays and seatstays, flat mount disc tabs and a 27.2mm seatpost. The front wheel uses Cannondale’s lefty hub, while the rear has a 142x12mm thru axle. There’s forward compatibility with electronic groupsets and internal cable routing for a dropper post too.
