Rotor ALDHU24 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 ALDHU24 axle

The ALDHU 24 crank arms only fit on the ALDHU24 axle!
The other ALDHU axles are 30mm.
Advantage of this system: it fits in the current bearings if you are now riding Shimano. Shimano always has 24mm axles.
