I got them as standard on my Cannondale SL Synapse. They seem perfectly ok, but not outstanding. The ride is smooth enough, but then again the frame is renowned for that. Grip is good in the dry, but I can't say in the wet 'cos I use my old hack in bad weather. P**ct*re resistance is fine as I've had no problems in several hundred miles of Lincolnshire gravel and potholes.
