2022 Cannondale Synapse Carbon 2 RLE review: One smooth ride - CyclingTips

Aug 2022 · Dave Rome

An overhauled endurance road platform meets modern all-road capability. It’s wonderful but there's a but.

Highs
  • Smooth ride quality, versatile tyre clearance, stable yet-not-sluggish handling, Shimano Ultegra Di2, easy to service component fitments, classy subdued styling.

Lows
  • SmartSense and the fact it’s a forced feature you’re paying extra for, wheels could be fancier for the money, mis-matched thru-axles.

Cannondale Synapse Disc Ultegra long-term review

Jan 2021 · Felix Smith

This is an initial score and could change as I spend more time on the bike

Highs
  • Cannondale's SAVE 'micro-suspension' is incredibly effective at taming rough tarmac and the low gearing and 32mm tyre clearance encourages more adventurous cycling

Lows
  • Messy cables up front detract from the otherwise clean overall design and the wheels and tyres are lacking modern endurance spec
