Profile's Column cranks are arguably the burliest cranks on the planet. Used by riders around the world who demand strength and durability from their drivetrain.
The column cranks feature heat treated oversize 4130 Chromoly crank arms with Profile claiming that these are the strongest they've ever produced!
Further strength is gained from the 22mm GDH CrMo axle with 8mm hex aluminum axle bolts. Make them ever even lighter with a titanium axle upgrade.
The cranks are bossless, a spline drive sprocket must be used.
Column Crankset includes LH & RH crank arms, 6"" 22mm GDH chromo axle, aluminum axle bolts/washers, and Column Crank Tool.
Lifetime Warranty to original purchaser.
