Surly Black Non-Drive Crank Bolt with Pre-Load Adjustment
Tired of annoying crank wobble or tricky bottom bracket adjustments? The Surly Black Non-Drive Crank Bolt is your precision solution for eliminating play and ensuring smooth pedaling performance. Designed specifically for the non-drive side of your crankarms, this isn’t just a replacement bolt; it’s a critical upgrade featuring integrated pre-load adjustment.
Forget wrestling with wrenches mid-ride or struggling with inaccurate tensioning. This unique bolt incorporates a simple flange interface that presses directly against your bottom bracket’s outer bearing cup when tightened. Turning the main bolt body with a standard 2.5mm hex key allows you to achieve perfect bearing pre-load before fully securing your crank arm – no special tools required! Micro-adjustment is effortless, eliminating unwanted side-to-side play that causes creaks and reduces efficiency.
Crafted from durable chrome-moly steel and finished in corrosion-resistant black oxide, it offers long-lasting reliability even in demanding conditions. Its robust M15x1.0 threading ensures a secure fit compatible with many modern cranksets requiring this specific setup.
