While it excels in performance and aesthetics, some note its high price and race-oriented stiffness as potential drawbacks.

Pros

  • Impressive aerodynamic efficiency

  • Sharp and precise handling

  • Lightweight and competitive with top aero bikes

  • Excellent blend of real-world usability and on-paper speed

Cons

  • Some components require careful maintenance

I didn’t brake through this section riding the Factor Ostro VAM. Boom, a PR that I haven’t been quite comfortable enough to match on other bikes.

FACTOR OSTRO GRAVEL VS FELT BREED CARBON - GRAVEL BIKE SHOOTOUT - Road Bike Action

feb 2023 · RBA Staff

A new generation of gravel race bikes

Pro
  • Felt: planted and in control, stable at high speeds, wide tire clearance (700x50mm), lots of frame mounts, good for non-racers.

  • Factor: excellent climber, quick handling, light weight, premium component spec, 1x44t chainring, Black Inc. bar/stem combo.

Contro
  • Felt: Zipp 303S wheels too stiff, knee colliding with rear brake hose on steep climbs, seatpost bottle cage difficult to use, lacking compliance for all-day efforts.

  • Factor: 1:1 gear ratio may be too hard for long rides, stiff ride quality, quick handling requires heightened focus on descents, internal routing complicates travel.
