ROTOR ALDHU Carbon cranks

Compose your one Rotor ALDHU Carbon crank. Starts with the crankarms. Available in 165mm, 170mm, 172.5mm and 175mm!

Combine the cranks arms with different types of spiders, chainrings and axles. Looking for a power meter? Then choose the INspider, or you can also add it in the future; this is the main advantage of the the modularity of ROTOR cranksets.

In short, a solution that will adapt to your needs without having to replace the complete set.

Weight crankarms 172.5mm: 262 gram (incl bolts)

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:
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!

Rotor ALDHU axels

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.
