Aluminum Rear Sprocket

• 100% German aluminum using ISO 7075-T651 for these sprockets receives an extra tempering which reduces distortion and provides optimal thickness
• 100% machined, no stamping or grinding
• Optimal tooth thickness results in maximum tooth and chain contact
• We leave the "cleaning" grooves out of our sprockets, because more aluminum contacting your chain means longer chain and sprocket life
• Moose Racing rear sprockets come anodized in black or silver; select Moose Racing rear sprockets are available in blue, red and orange

fits for: Beta RR & X-Trainer
