With Rotor ALDHU you can compose your own crankset. Wether you like the lightest option with spiderring or you like to change your Rotor chainrings like you're used to. Maybe you like to change you crankarmlength according to the circumstances. With the new Rotor ALDHU system this is al possible. Rotor innovates! ✅lightest crankset ✅superstiff ✅ excelent design
Compose your one Rotor ALDHU crank. Starts with the crankarms. Available in 150mm, 155mm, 160mm, 165mm, 170mm, 12.5mm and 175mm! 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.
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: Double 53/39 52/36 Compact 50/34
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!
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.
