YT Industries Jeffsy 29 Core 3 review

Aug 2022

The YT Jeffsy 29 Core 3 is a very capable all-mountain bike which can handle the rough stuff but is equally at home on flow trails and jumps. While the specification list is solid for the money, it's worth paying extra attention to frame sizing and geometry to get the ride you want. With a longer dropper and some tougher tyres this bike has what it takes to be a real challenger when it comes to the best mountain bikes.

YT Jeffsy 29 Core 3 review

Ed ThomsettMay 2022

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

Pros
  • Predictable ride quality

  • A solid suite of parts

  • Great for riding just about any terrain

Cons
  • Conservative head angle

  • A good price, but the outrageous value YT’s reputation was built on isn’t there
