ROTOR Aldhu Crank

ROTOR introduces ALDHU 3D+ crankset with direct mount spidering to offer more options to riders who want a crankset that meets their own needs. The innovative modular structure makes each part completely independent of the others to meet all rider profiles and frame standards.The 7055 CNC machined cranks come with a 7075 aluminum machined oval or round spidering to save more than 30g compared to a classic star + chainring set. But the big difference is the ability to have extremely fine tuning of the spidering with OCP Mount to increase performance.OCP Mount, a proprietary patent pending technology, allows the oval spidering to be adjusted to the degree for biomechanically optimized pedaling.The 12.5% ovality (halfway between QRings and QXL) amplifies the benefits of oval chainrings. No other chainring on the burgeoning oval market offers this fit, especially when combined with the spidering ofALDHU which makes it a dedicated performance package.And thanks to the modular design ofALDHU, you can upgrade any part of the package without having to change the entire crankset.ALDHU 3D+ is the lightest crankset ever designed by ROTOR.Details:Direct mount crankCranks sold aloneFeatures:Crank length 170Material Aluminium Crankset axle 30 mmCrankset standard Rotor UBB30 (BB30 long axle)Case IncludedNo Compatibility Dual ChainringsMono
