    LEFTY'S front hub maintenance... need help!

    I'm doing maintenace on my hubs. Rear one with ball bearing is a piece of cake but the front one, the lefty's is new to me. Is it possible to do a maintenance on thoses two bearings ? Lubricate them or something ?

    Best Regards.

    The front wheel also uses sealed cartridge bearings. Once shot you just have to replace them.....Every once in a while I remove the front wheel (Mainly after I hosed my bike off) and coat the lefty axle and the bearings with some grease.
    That's about it as as far as maintenance goes.....

    Is it usual for the bearings to wear out after four months?

    You can pop the seals out with an awl flush the old grease out and relubricate them. You might be able to do this with the bearings inplace. I can do it on my road bike but have never tried it on the Lefty,

    You can, but it's a better choice to take them out. Reason being, there's a seal on each side, and unless they're both off you'll have a half dissolved grease floating around the bottom half of the bearing. This will end up screwing up the viscosity of your new grease. Just, FWIW....

    Not unless they are contaminated.

    Thanks a lot for all theses informations.

    Another question, does the brake cable housing running in the swingarm is full lenght or simply 2 pieces? I have Avid BB7.

    Regards

    Either or...you can run it full length (Hydraulic brake lines) or split the housing for a mechanical set up on the down tube like for the rear dérailleur... you just need some housing stops (ferules) for that.

    Not really. But, it also depends on how and where you ride. Do you hose the bike of a lot? Or maybe remove the lefty wheel a lot for transportation? If so, do you use the proper torque when putting the wheel back on?
    Just replace the bearings, and always use a torque wrench when installing the wheel and see if it happens again.

    I ride in the UK in all conditions so the bike gets washed regularly. Low pressure hose not a jet wash.

    New bearings going in tomorrow.

    Fingers crossed!!

    I am assuming you have a rush? this is the only recent model to have the internal cable routing. The brake lines dont go through the swingarm, only the shift cable. If the brake cable ran through you wouldnt have the adjustability of upgrading to a hydraulic brake system because the hydraulic lines are bigger.

    hope this helps, if your bike does have brake cable routing then I believe it is one piece. If this is the case, post some pics please!

    Yeah, you can only split the mechanical line on the downtube, not the swingarm. My bad. I guess I didn't read the whole thread...
