Titanium Spinal Cranks

A titanium version of our Spinal cranks. Each part is machined entirely from a solid piece of 6Al-4V (Grade 5) titanium, with the arms being sandblasted for a clean matte finish. These use a proprietary spline-drive system that allows a wide range of chain-line adjustments without a need for "offset" sprockets (see details below). Includes full crankset, pre-load adjustment rings, bottom bracket spacers, sprocket, and your choice of steel or titanium spindle and bolts. Spindle is 24mm diameter.  146mm BMX spindle - chainlines 41mm to 45mm160mm MTB spindle - chainlines 49mm to 53mm 170mm crankset w/titanium 160mm spindle and bolts = 650g34T Sprocket w/adapter =
