Alert: We have changed our Rating for the Cannondale Teramo from a Don’t Buy: Safety Risk to Recommended because the buckle on the chinstrap is different, and the helmet now passes our chinstrap test. It also performed well in our other tests and assessments. If you own a Cannondale Teramo helmet with the old buckle design, we recommend that you do not use it. If you are buying a new Cannondale Teramo helmet, be sure that it has the new buckle design. For more information, including images of the old and new buckles, see our full story here.
