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

Cannondale Synapse Carbon 105 SE review

Apr 2019 · Warren Rossiter

It’s just that in Cannondale’s pursuit to make the SE all things to all people, and make the most of its generous tyre clearances, the addition of the WTB/Formula wheelset combined with big tyres dulls the nimble edge of the Synapse when it comes to rapid progress on the road.. .

Highs
  • Blissfully smooth with well-balanced handling

Lows
  • The weighty wheel and tyre combo dulls some of the road excitement
