Rotor ALDHU and Shimano 9100/8000 Q Outer Chainring 110BCD
Rotor's new modular ALDHU 3D+ system features a clever design and an elegant finish that will enhance the aesthetics of any setup and allows the spider, chainring, and other parts to be switched out and upgraded as and when required. The ALDHU and Shimano 9100/8000 Q Outer Chainring 110BCD is compatible with ALDHU 3D+ and 4-bolt Shimano cranks and is constructed from 7075 aluminium for reduced weight and increased strength to suit even the most powerful riders.
Mounted onto ALDHU cranks, the chainring position can be adjusted in 1-degree increments to suit the individual biomechanics of a rider, configuring their OCP (Optimal Chainring Position) so power transfer is maximised at the optimal point of the pedal stroke. The modular system allows the spider, chainring, and other parts to be switched out and upgraded as and when required.
As part of a Shimano setup, the chainring will be set to OCP 3 which is an intermediate position suited to, and most frequently selected by, most road riders.
