2020 Cannondale Topstone 105

Jun 2020

Cannondale's attention to detail on the Topstone is excellent, and they've made some really interesting design choices to stand out in an increasingly-crowded category. Apparently they've succeeded -- the Topstone 105 has been the third most popular bike on all of 99 Spokes this year.

Highs
  • Well balanced

  • Descends well

  • Good power transfer

Lows
  • No mount points on the fork

  • Cheap bottom bracket

Cannondale Topstone Carbon Lefty 3 gravel bike review

Aug 2020 · Josh Ross

The Cannondale Topstone Lefty 3 draws from the best ideas in Cannondale’s history. It’s a full-suspension gravel race bike that brings back the out-of-the-box thinking we've come to expect from Cannondale

Highs
  • Lots of tyre clearance

  • Front suspension is easily locked out

  • Adaptable for different uses

Lows
  • No mounts on the fork

  • Mudguards aren’t available

Cannondale Topstone Carbon Lefty review: Suspension makes it better - CyclingTips

May 2020 · James Huang

The changes sound modest on paper but the difference you feel in the saddle is far greater than you might expect, and while that Lefty Oliver […]

Highs
  • Exceptional ride quality front and rear, well-tuned front suspension fork, nimble handling.

Lows
  • Lots of Cannondale quirkiness, heavy.
