My wife surprised me with a new bike this past week! It's a 2012 cannondale superx. It's my first carbon fiber bike. It has a super nice ride compared to the hybrid I was ride. I've noticed that with moderate to heavy front braking bike develops bad vibration. The vibration gets worse when using a combination of rear and front brakes. No vibrations occur if using only the rear brakes. I've tested on various road surfaces so it's not the road. The vibration occurs at all speeds. It feels like the vibrations are coming from the bottom bracket. Any clues are to what is going on? Combination of EuroTRP/Mavic Kysrium Equipe wheels? I'm going to call the LBS tomorrow. But, would like some info before I talk with them.
