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
