YT Jeffsy Core 4 29 — Size Small, Carbon, Full Suspension MTB


The YT Jeffsy Core 4 29 is a top-tier trail bike that perfectly balances efficiency and fun. Built around a lightweight carbon frame and featuring FOX Factory suspension front and rear (both with Kashima coating), it offers 150mm of smooth, controlled travel. The SRAM X01 Eagle 12-speed drivetrain delivers precise shifting, while the RaceFace ARC 30 wheels and Renthal cockpit give it a premium trail feel. At just 27.9 lb, it’s light, playful, and confidence-inspiring on every descent.


Why we love it:

This bike feels effortless uphill and unstoppable downhill. The Jeffsy Core 4 29 combines pro-level components, buttery FOX Factory suspension, and YT’s aggressive geometry into a ride that’s equally fast and fun — ready for big climbs and bigger descents.
