The Fiend Kurbelschrauben are high-quality crank bolts designed specifically for BMX and freestyle riders who demand reliability from every component on their bike. Built to secure your crank arms firmly to the bottom bracket spindle, these bolts help keep your drivetrain tight and responsive, even under heavy landings and aggressive riding. Whether you are riding street, park, or dirt, solid crank bolts are essential to avoid unwanted play, creaks, or loosening during sessions. Fiend is known in the BMX world for durable, rider-tested parts, and these crank bolts follow that same philosophy.
These Kurbelschrauben are typically made from robust steel or similarly strong materials to withstand repeated impacts and constant torque from pedaling and tricks. They are a smart upgrade or replacement when refreshing your crankset, especially if your original bolts are worn, rounded, or rusted. Easy to install with standard tools, they allow you to maintain your bike at home and keep your setup dialed. Pair the Fiend Kurbelschrauben with a quality crankset and bottom bracket to enjoy a more secure, confidence-inspiring ride every time you roll out.
