The Renthal 184U-525-44P-HA is a 44-tooth Ultralight rear sprocket designed for 525 chain pitch road and road racing applications. CNC machined in Manchester, UK from high-strength, specially enhanced 7075 T6 aluminum alloy, this rear chainwheel delivers the maximum reduction of unsprung weight at the rear wheel for superior power transfer.

Key Features:

• Hard anodized surface finish — an integral coating that significantly increases surface hardness and wear resistance for extended service life on street and track
• 66% lighter than steel — precision computer-aided Ultralight design minimizes revolving unsprung mass
• CNC machined to extremely tight tolerances — ensures precise fitment, concentricity, and optimal load dispersion
• 7075 T6 aluminum alloy construction — high-strength material purpose-built for demanding performance applications
• Self-cleaning grooves between every tooth on both sides to prevent debris buildup and maintain consistent drive
• 44 teeth, 525 chain pitch
