Polycarbonate Sprocket Guards

Protect your chain and sprocket from costly curb impacts. One curb strike is all it takes to damage a sprocket, derail a chain, and ruin a race weekend.
 
Boreas Industries Sprocket Guards help absorb and deflect impact energy before it reaches your drivetrain. Built for racers who demand reliability, these guards help absorb and deflect impact energy before it reaches critical components.
 
Polycarbonate Construction
The guard is manufactured from 3 mm thick polycarbonate, chosen for its exceptional impact resistance and toughness. Unlike brittle materials that crack under load, polycarbonate flexes to absorb impact energy, allowing the guard to act as a protective bumper for your sprocket.
 
Precision-Machined Delrin Spacer
Each spacer is machined from Delrin for excellent dimensional accuracy, low weight, and durability. This ensures precise fitment while minimizing unnecessary rotating mass.
 
Steel or Titanium Hardware
Choose between corrosion-resistant steel or titanium hardware to suit your needs. The titanium hardware option reduces weight by 1.2 ounces compared to steel while maintaining excellent strength. Both options include nylon lock nuts for secure installation.
 
Split Design
Split design for easy installation and maintenance of chain and sprockets.
Proudly engineered and manufactured in the USA.
