YT Jeffsy Core 4 review – MK3 version of the excellent all-mountain bike

ago 2024 · Rich Owen

  • Rides lighter than its actual weight

  • Useful internal and external on-bike storage

Contro
  • Matte black carbon finish is easily scratched and scuffed

  • Not the biggest internal storage opening

YT Industries Jeffsy Mk3 Core 4 mountain bike review

lug 2024

The YT Jeffsy Mk3 Core 4 is a capable all-mountain bike which, thanks to its spec, has a bias towards descending but is equally able to climb. While the spec is hard to argue with and the value for money is excellent, it's worth paying attention to the frame sizing and geometry to get the ride you want. The bike could be improved further with a longer dropper post and a slacker head angle but YT has done a good job continuing to polish the already excellent Jeffsy.

We see how the most affordable version of the Jeffsy handled Squamish's slippery trails.

Pro
  • Excellent value (even more so when it's on sale)

  • Very capable descender, while still remaining manageable on mellow terrain

  • Wild or mild paint options

Contro
  • On the heavier side for a trail bike

mar 2024 · Ben Haworth

The YT Jeffsy Core 4 is a bike that arrives in a box that is not quite perfect out of the box. BUT... there is loads of potential here.
