Sometimes hubs get stuck and the wheel doesn’t rotate properly. This article will explain how to fix this problem on 135mm solid axle hub, with solutions for either AUTOMATiQ (AHI) or Manual (MHI) hub interfaces.

Backward compatibility

This guide is compatible with legacy 135mm solid axle hubs (Commercial/CO, Sportive/SP, Cargo/CA, N360, N380, N380SE).

Problem diagnosis

Inspectez le moyeu. Suivez ce guide si vous détectez :

• Le moyeu ou la roue ne tourne pas correctement.
• Le CVP semble être bloqué en milieu de plage ou la plage de rapport semble être limitée.
• Le moyeu semble être bloqué soit en surmultipliée totale (rapport élevé), soit en sous-multipliée totale (rapport faible).

Solution

Pour un moyeu bloqué en milieu de plage :

• Si le moyeu a moins de 2 ans, renvoyez-le en utilisant le formulaire de demande de garantie. Les moyeux enviolo sont des contenants clos et doivent être renvoyés pour une inspection approfondie.

Pour un moyeu bloqué en surmultipliée totale ou en sous-multipliée totale.

• Vous devrez débloquer le moyeu à l'aide de pinces combinées. La procédure dépend du système de transmission que vous avez - AutomatiQ ou Manuel.
• Choisissez le système de transmission ci-dessous et suivez les étapes :

AutomatiQ

Bikes with an AUTOMATiQ hub interface (AHI):

1. Disassemble the AHI-equipped wheel from the bike frame.
2. Disassemble the AUTOMATiQ hub interface from the wheel.
3. Unblock the hub using combination pliers.
   See detailed instructions below
4. Reassemble the AUTOMATiQ hub interface on the 148mm wheel.
   See detailed instructions
5. Reassemble the AHI-equipped wheel on the 148mm bike frame.
   See detailed instructions
6. Calibrate the AHI using the AUTOMATiQ App.
   See detailed instructions

Manual

Bikes with a Manual hub interface (MHI): 

1. Disassemble the MHI-equipped wheel from the bike frame.
2. Disassemble the AUTOMATiQ hub interface from the wheel.
3. Unblock using combination pliers.
   See detailed instructions below
4. Reset the 148mm hub to full overdrive.
   See detailed instructions
5. Reassemble the Manual hub interface on the 148mm wheel.
   See detailed instructions
6. Reassemble the MHI-equipped wheel on the 148mm bike frame.
   See detailed instructions

Unlocking the hub using combination pliers

Video instructions

Tools

• Combination pliers
• Vice

Unblock instructions

1. Hold the wheel in place using one hand.
2. With your other hand, use combination pliers to hold the shift driver.
   
   • The shift driver part is the spline nut closest to the hub (see photo below).
   • Be very careful not to damage the shift driver.
3. Spin the wheel clockwise.
4. At the same time as the wheel is spinning, carefully rotate the shift driver using the combination pliers:
   • Stuck in high gear - rotate the shift driver clockwise.
   • Stuck in low gear - rotate the shift driver counter-clockwise.

Be careful when unblocking the hub

While using the pliers, be careful not to damage the shift driver. Otherwise, it will be impossible to mount the hub interface later. The shift driver is one of the two splined nuts, the one that is closest to the hub.

Your wheel is ready to go

If you successfully follow the steps above, then the hub should be unblocked and the bicycle should be riding smoothly again.

If the problem persists, contact support.
