For sporty recreational riders, or hilly races, the aluminium Energy crankset is available with compact 50/34 chainrings made from hard-wearing 7075 aluminium. Cutting-edge manufacturing techniques allow us to cold-forge hollow aluminium arms, cutting weight without any sacrifice in stiffness. The spindle is aluminium too, forged from ultra-strong 7075. It's available with spindles for either BB30 or MegaExo bottom brackets. Even the chainring bolts are 7075. The result is a high-performance crankset at a low weight. A mix of polished and sandblasted black anodising, complemented by distinctive colour graphics, gives the Energy a racey look.
