The Profile Elite Crankset is the stiffest crankset Profile have ever made. Oversized and gusseted, the Elite arms are constructed of heat treated 4130 Chromoly, there's a reason freestylers the world over use these as they not just bombproof, they are nuclear proof! The Elite crankset includes left and right crank arms, 22mm GDH Titanium axle, 4-bolt spline drive spider and outboard Euro bottom bracket( in a choice of several sizes and colours), and Black 8mm GDH aluminum axle bolts. They come in at just under a kilo for the set up (excluding chainring). The Elite Cranks are packaged in a keepsake metal box with original lithograph artwork by Adi Gilbert of Profile's owner Jim Alley welding Elite crankarms. They are the LUX Team crankset of choice and just like all Profile cranks, they are made in St. Petersburg, Florida, USA.
