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.

Feb 2022 · Stu Kerton

Beautiful to ride with a great blend of speed and comfort, but the electronic aids aren't that special – and aren't for me

Highs
  • Excellent geometry layout

  • Comfortable

  • Reflective seatstays are a clever touch

  • Trainer adaptors as standard

Lows
  • Cable routing not as clean as some

  • Low end wheelset comparative to the frame
