We added a new heat treatment process, thicker tubing and made them with a stiffer shape.
All for those that need the security of a stress-free crank. The Demolition crew stands by them and swear they are the strongest cranks they’ve ridden. Heat-treated tubular chromoly arms with a forged spindle boss that is flush with the arm to reduce ankle scarring, 48 spline, 19 mm hollow chromoly spindle and flush mount spindle bolts. RHD/LHD compatible.
