The RENTHAL Ultra-Light 154U mud-resistant sprocket is designed for demanding riders who want to lighten their drivetrain without sacrificing strength. Machined from 7075 T6 aluminum, it features a profiled tooth design that facilitates mud evacuation and minimizes friction between the chain and the sprocket. The hard anodized finish enhances the surface and protects the part from wear while giving it a sleek aluminum finish.
Strategic cutouts on the sprocket lighten the part without compromising its rigidity, reducing rotational mass for a more responsive rear end. Its tooth geometry is optimized to limit power loss due to mud buildup and maintain good chain engagement on wet or muddy terrain.
Suitable for off-road (MX, SX, enduro) and also relevant for certain roadsters, this RENTHAL sprocket is aimed at riders seeking reliability, longevity, and performance in challenging conditions.
