The XRAY 343074 X8 Carbon Belt Tensioner Holder is designed to let you dial in belt tension with better resolution. The longer carbon fibre profile reduces flex while enabling tighter settings on smaller pulley setups, improving drive consistency.
Crafted from high-quality carbon fibre, this tensioner holder adds minimal weight while providing the stiffness needed for repeatable belt tension. It is a practical upgrade for hobbyists wanting predictable drivetrain response during practice and race days.
