If you transport your 2014 Synapse by removing the front wheel and laying the bike flat in your SUV or other vehicle, check your rear brake cable housing where it enters the head tube. My rear brake cable housing cracked after transporting my bike approximately 30 times. When the bike is laid down flat with the front wheel removed, it bends the rear brake cable housing at a sharp angle where it enters the frame. Doing this repeatedly cracked the cable housing. See the attached photo.
