The new Micro Adjust Spider (MAS), on 3D+ cranks offers more positions to suit every rider’s needs. Our new advanced MAS spider has an alternative bolt hole placement allowing for intermediate positions between existing OCP (Optimum Chainring Position) of the 'Q-Ring'.
A standard crank in combination with the OCP of the Q-Rings, allows approximately 5 degrees of adjustment.
The MAS spider when used with Q-Rings offers half positions giving approximately 2.5 degrees. This means that you can micro adjust the position of your 'Q-Rings', to suit your riding style.
