Stel je eigen ALDHU crank samen, begin met kiezen welke cranklengte je hebben wil. De meest uitgebreide keuze vind je bij de ROTOR ALDHU: van 150mm tot 175mm.
The Rotor ALDHU crank are made according to the Rotor 3D + system, ie extruded aluminum so that the aluminum molecules of these cranks are close and straight together, which gives the crank a noticeable stiffness.Almost no more power is lost in bending soft material: A much more direct transfer of your power to the chain.
Rotor ALDHU spiderring or chainrings with spider
So choose what you prefer. As light and stiff as possible ?: Choose the ALDHU spidering (Qring or NoQ = round)
To remain flexible and to be able to replace your sheets separately: choose an ALDHU spider with loose sheets.
Both available in:
Weight Spider ring Qring (52/36): 188 grams
Weight outside leaf Qring 52 teeth: 106 grams
Weight inside leaf Qring 36 teeth: 27 grams
Weight spider: 52 grams
Weight of blade bolts (sitting at spider): 8 grams
As can clearly be seen on the photo of the loose spider, the new ALDHU system is multi-adjustable.So there are no more 4-5 adjustment options on the Qrings, but you can adjust the entire spider to the correct position!
Rotor ALDHU assen
Assemble your own Rotor ALDHU, so choose your axle yourself. By default, the "standard axle"
The currently available shafts are 30mm. So also, just like with the Rotor 3D +, adjust your bearing if you are still driving with a 24mm shaft.
Advantage: the 30mm axles are stiffer and therefore provide better efficiency.
In most cases you need an offset axle while using discbrakes.
This spiderring Q-ring is suitable for the new directmount system from Rotor (ALDHU, VEGAST 92)INpower etc.) From one unit, so super light and super stiff!
