The Yakima Copperhead Bike Mount works perfectly with nearly any road bike and any mountain bike with a 9mm or 10mm quick release fork. It also works with any round or square bar, so even if you have a rack from one of those other companies, the Copperhead will still work.

• Works with round or square crossbars
  
• Aerodynamic fork block for stability and better fuel economy
  
• Doesn't touch paint on frame tubing
  
• Lock-compatible (lock cores sold separately)
