Aluminium Mud-Resistant Sprocket 441U - 428 46 Teeth by Renthal

Ultralight mud-resistant sprocket designed for off-road use, made from 7075 T6 aluminium to maintain an excellent balance between weight and strength. The tooth geometry and anodisation facilitate mud evacuation and minimise power loss in MX, SX, and enduro conditions.

Design and Materials

• Precision-machined 7075 T6 aluminium to provide good mechanical resistance while reducing the weight of the part.
• Surface anodisation that hardens the material on the surface and enhances appearance without compromising structural strength.
• Strategically positioned cutouts to lighten the sprocket without diminishing its mechanical integrity.

Practicality and Features

• Tooth profile designed to facilitate mud evacuation, limiting accumulation and maintaining smoother transmission.
• Ultralight mud-resistant design that simplifies maintenance on muddy terrains and reduces the frequency of necessary cleaning.

Usage and Performance

• Noticeable weight reduction due to the Ultralight design, contributing to lower unsprung mass for improved responsiveness.
• Reduction of power loss related to friction between chain and sprocket thanks to the tooth profile, promoting more efficient transmission performance.
• Design and material choices aimed at enhanced durability and longevity in off-road use.

Advantages

• Cross type, suitable for off-road practices.
• OEM Reference 441U-428-46GPBK
