YT JEFFSY Core 4 XO T-TYPE MTB All Mountain Carbon Fog Green

YT JEFFSY CORE 4 - Trail Excellence Refined
At the top level sits the CORE 4, with its high performance and low-weight Ultra-Modulus carbon frame. FOX delivers Factory level suspension with the 36 and Float X combination, with the former receiving the gravity-focused GRIP X2 damper for enhanced traction and chassis stability.

DT Swiss has three decades of high-end wheel manufacturing experience, so the EXC1501 Spline package is a natural choice. Enduro-rated carbon fiber rims laced to top-tier 240 hubs assist with line control and acceleration efforts. A great wheelset needs tires to match, which is why the Maxxis Minion DHF/DHR II combo gets the sticky Maxxgrip compound up front for increased confidence.

The Hayes Dominion A4 brakes further improve confidence with their light lever feel and massive stopping power, while SRAM’s X0 Transmission drivetrain ensures smooth ratio changes.

Finishing this build is the YT Postman V2 with adjustable drop, SDG Bel air saddle, ODI grips, and YT exclusive Renthal Apex stem and Fatbar.
