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
