YT Jeffsy 29 Core 3 review

Ed Thomsett

An excellent complete package that makes fun of all but the gnarliest descents, thanks to a head angle that feels too steep

  • Predictable ride quality
  • A solid suite of parts
  • Great for riding just about any terrain
  • Conservative head angle
  • A good price, but the outrageous value YT’s reputation was built on isn’t there

Vital MTB
2021 YT Jeffsy Core 3 29 Bike

Loganbrown

Not your typical Vital bike test...

  • All fun, all the time
  • Capable climber
  • Excellent parts spec
  • Encourages aggressive riding
  • Confident descender for both rocks and jumps
  • A true all-rounder
  • Frame protection quickly peels
  • Seemingly forever sold-out (even before the bike boom)

YT Jeffsy Core 3

Jeremy Benson

The Jeffsy Core 3 is the latest version of YT's popular longer travel trail bike. While other brands have gone to extremes with their geometry, this bike's...

  • Excellent value
  • Great build for the price
  • Composed and confident descender
  • Super quiet
  • Well-rounded performance
  • A little heavy
  • Not the fastest climber
  • Geometry feels a touch dated
  • Limited water bottle space
