Rotor Aldhu Carbon crank

Answer of Diego

Hello, yes, it all depends on your bottom bracket. Rotor only makes 24 or 30 mm axles. You will need a 24 or 30 mm pressfit bottom bracket. I recommend 30. Also think about the axle. For a road bike it is a road axle, otherwise for a gravel frame it will be an offset axle. Don´t forget the spacers to insert between the crank and the frame, this depends on the bottom bracket. You will have a table with the axle. It will be a small additional purchase.

bonjour, oui, tout dépend de votre boîtier de pédalier. rotor fabrique que des axes en 24 ou 30 mm. il vous faudra un boîtier pressfit en 24 ou 30 mm. je vous conseille du 30. pensez aussi à l axe. pour du vélo de route c est du road axle, sinon pour un cadre gravel ce sera du offset axle. n oubliez pas nous plus les entretoise à insérer entre la manivelle et le cadre, cela est en fonction du boîtier. vous aurez un tableau avec l’axe. ce sera un petit achat supplémentaire

Answer of Michiel

Then you should not have these cranks. These cranks require a 30mm axle. The cranks you need to replace Ultegra are the cranks that require a 24mm axle. You have to buy the axle separately.

Dan moet je niet deze cranks hebben. Deze cranks hebben een 30 mm as nodig . De cranks die je moet hebben om Ultegra te vervangen zijn de cranks die een 24 mm as nodig hebben. De as moet je er apart bijkopen.

Answer of Chaz

You'll need to replace your shimano bottom bracket to a rotor bottom bracket as well .

Answer of João

You have to get the 24mm axle if you have a Shimano crankset or the 30mm spindle if you owned a SRAM crankset along with a specific ROTOR Bottom bracket.

Answer of Diego

Hello, you must additionally purchase a 24mm road axle, no offset and spacers for 24mm axle in order to adjust the distance between each crank and the bottom bracket.

Bonjour, vous devez acheter en plus un axe de 24 mm road, no offset et des entretoises pour axe de 24 mm afin de régler la distance entre chaque manivelle et le boîtier

Answer of Baptiste

No, it is only for a rotor with a 30mm axle.

Non c’est que pour du Rotor avec axe 30mm

Answer of Michiel

The axle determines what your chainline will ultimately be, not these arms. Good luck!

De as bepaalt wat uiteindelijk je kettinglijn wordt, niet deze armen. Succes ermee!

Answer of Dennis

Steve, the crank itself does not determine chainline. Rather the different lengths of Rotor axles you pair your crank with will determines the chainline for your bike

Answer of Baptiste

No I don´t think these cranks only fit one axle and rotor chainrings. The axle must be 30mm with a 30 bottom bracket and for older bikes with spacers.

Non je ne pense pas ces manivelles ne s adaptent qu à un axe et des plateaux rotor. L axe doit être en 30mm avec un boîtier de pédalier en 30 et pour des vélos un peu anciens avec des entretoises.

Answer of Allen

it's for 30mm axle

Answer of Christos

Rotor aldhu can only be used with the rotor 30mm or 24mm axles. So if you have the bearings that are either 30mm or 24mm internal diameter, then these arms will fit the bb. For the chainrings it depends on which spider you choose. For these arms you need an aldhu spider. I know rotor has 2 types (power or no powermeter) and sigeyi makes a powermeter spider (I have it on my bikes). If your chainrings have 4 holes, you’ll need a 4x110 aldhu spider. Otherwise, if your Inga have 5 holes, you need a 5x110 spider.

Answer of Daniele

Hello look the pin has 30 internal diameter, you must know the external diameter of the bottom bracket shell, and the length it has, and the type if it is a threaded or a pressfit, so the data you find example: 4130 tells you cha you have a box of 41 in external diameter, 30 is the diameter of the axis of the cranks, and 86.5 is the length of the box, the pressfit are compatible with 3 lengths of central box, but I don´t know which frame you have so I can´t tell you.

Ciao guarda il perno ha 30 di diametro interno, tu devi conoscere il diametro esterno della scatola del movimento centrale, e la lunghezza che ha, e la tipologia se è un filettato o un pressfit, quindi il dato che trovi esempio : 4130 ti dice cha hai una scatola da 41 di diametro esterno, 30 è il diametro dell asse delle pedivelle, ed 86,5 è la lunghezza della scatola, i pressfit sono compatibile con 3 lunghezze di scatola centrale, però non so che telaio hai quindi non saprei dirti.

Answer of tai

Actually rotor does provide 172.5mm carbon aldhu crank. I guess they are just out of stock

Answer of Daniele

Hello good morning, look it is not compatible because it has a tooth and a pin of different sizes, plus it is not compatible with the chainrings and with the sram crankset, you have to take the cranks of the sram, but first you have to see what diameter of the axle you have in the crank.

Ciao buon giorno, guarda non è compatibile perché ha una dentatura ed un perno di dimensioni differenti, in più non è compatibile con le corone e con l’ingera guarnitura sram, devi prendere le pedivelle dello sram, ma prima devi vedere che diametro del perno hai nella guarnitura .

Answer of Dennis

This Rotor ALDHU crank arm is incompatible with SRAM. Axle design and size are different for both brands. You will need the corresponding SRAM Force DUB crank arm, this arm is also made of carbon and comes in 165mm length. Both arms are almost similar in weight.

Answer of Avelino

Good, the shaft is 30mm in diameter but also available in 25mm but I think only in aluminum.

Boas, o eixo é de 30mm de diâmetro mas também existe em 25mm mas acho que só em alumínio.

Answer of Andrés

The preload washer is included in the left crank and for the pedals it has the thread to be able to mount them. The pedals already have the thread made to be able to mount them on the cranks

La arandela de precarga va incluida en la biela izquierda y para los pedales lleva la rosca para poderlos montar. Los pedales ya llevan la rosca hecha para poderlos montar en las bielas
