One Year Review
The carbon Synapse itself has been a perfect real world road bike. Alloy or carbon you will not regret this choice for any road purpose. Ultegra running gear has been slick, durable and not required much adjustment. It just works. The included WTB wheelset has held up nicely and tubeless conversion is easy. Ability to run 32c tires on this bicycle is great and no loss of speed. The stock WTB Exposure tires are so prone to flats I consider them a defective product which should not be sold. After interacting with WTB CS regarding these tires, I will never purchase or use a WTB tire again. They know better and continue to sell these tires and make excuses.
Love this bike!
Exactly what I was looking for - something to ride around in gravel and small rocky paths & yet sturdy enough to take on long rides on the road. This bike does it all!
What a nice bike!
Bought this after putting 30K miles on my last Cannondale(CAAD3). What a nice bike! Still works great as a road bike but the wide tires make the riding even more comfortable. I can easily go off the side of the road if traffic requires it and don't feel like I'm going to get a flat like I did with my old 700x23s. The disk brakes are great, the frame is a really nice color and the carbon works together and is comfortable on longer rides. Very happy!
