Cannondale Synapse Carbon Disc Dura-Ace review

Feb 2020 · Warren Rossiter

Aiding the ride feel up front is Cannondale’s SAVE hollowgram carbon bar and stem, which eschews a standard round clamp in favour of a crescent-shaped cradle that the bar sits into.

Highs
  • Likeable lively handling, light chassis, smooth ride

Lows
  • Middleweight wheelset at odds with superbike chassis
