Cannondale caadx disk 105 or Cannondale synapse disk 105
I am looking to purchase a new bike to use on the road and some light gravel tracks in debyshire. I like both the caadx disk 105 and the synapse disk 105. The reason for considering the synapse is i like the way the cables go through the frame and the higher gearing, however i am insure if the bike /wheels will be strong enough for the gravel tracks. I will also be using this bike to do the london to brighton ride in june.
