Reviewed: Felt Breed Advanced GRX 820 Gravel Bike - Cyclocross Magazine - Cyclocross and Gravel News, Races, Bikes, Media

Sep 2024 · Clifford Lee

We put the Felt Breed Advanced GRX 820 to the test. The bike of choice for the Felt United gravel team has 50mm tire clearance and plenty of mud clearance for #shorttrackgravel. See if it's the bike for you.

  • Stable and confidence-inspiring geometry

  • Great power transfer efficiency

  • Good bump compliance from seatpost and frame

  • Versatile for gravel racing and fast riding

  • T47 threaded bottom bracket design

  • UDH compatible dropout

Lows
  • Bottom bracket developed creaking after a few months

  • Downtube is awkward to grip for portaging

  • Vittoria Terrano Dry tires lose grip quickly with wear

  • Wheels are not the lightest (claimed 1545g)

  • No fender or rack mounts

  • 140mm rear rotor is small

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
