Felt Breed 20 gravel bike in review

May 2022 · By

With the Felt Breed 20, another affordable gravel bike is trying to join the big players. It has an aluminium frame and mechanical SRAM gears. In addition, many mounting points are supposed to provide utility for everyday gravel riding. This group test reveals whether that’s enough to outdo the 18 best gravel bikes of the year.

Highs
  • Many mounting options

  • Premium tire

  • Predictable handling

Lows
  • Handlebar drops too short

  • Reduced comfort

  • Components limit the bike
