With the Cannondale Slate, Cannondale anticipated the gravel trend from 2016: The drop bar bike rolled on 650b wheels with voluminous tires and a Lefty fork at the front. This concept has now been revived in a modernized version: The""Cannondale Topstone Lefty"" uses a rear triangle that can release up to 30 millimeters of suspension travel with a joint between the seat stays and seat tube, in mountain bike jargon this could well be called a softtail. The Lefty-Oliver fork is somewhat stingy in terms of suspension travel compared to its mountain bike counterpart, but at 30 millimetres it should be a good match for the rear triangle. The 27.5-inch wheels with tires up to 47 millimetres wide provide additional comfort on gravel trails.
