The Rotor Aldhu-R cranks use direct mounting (DM), the lightest and most adjustable available option for chainring attachment. Through machining, the one-piece aluminum chainring is mounted directly to the crank spindle, eliminating the need for bolts. They are available in 1x or 2x with round or oval chainrings.
