If you own a 1971-1974 Norton Commando and you've ever suffered a rear axle break where the main axle threads into the dummy axle at the brake drum you'll be interested in the one-piece axles from Don Pender. Made of stainless steel, they replace the stock two-piece setup, which has been known to fail in high-stress applications. Installed through the chain side, the brake drum can be left in place during wheel removal. One-piece axle at top. $70.
