Hey as the title suggests, I need help getting to these bearings. Wheels are only 3 months old but have been ridden in a lot of rain and since getting hosed down on the weekend, are now running very rough.

I have loosened the bolt of the collar turned it ant-clockwise so there's now a lot of play in the hub, but can't seem to find a way of removing the axle and accessing the bearings. I assume they are the cartridge type and can hopefully clean and re-grease.

Any pointers would be great :mrgreen:

    This video might help - it's for the Racing 5 but I'm pretty sure that the Quattros are more or less the same construction:

    It's been a while since I delved into the innards of my Racing 5 LGs but I think I followed this guidance when I did. Trust me, if I can manage to do it and get the wheels running smoothly again, anyone can.

    This is another video which tells you how to adjust the pre-load which is also important when it comes to getting them to run well:

    Good luck.

    chances are, if its the rear wheel, then its the bearings in side the freehub, which can be replaced but its a bit of a pain or £60 for a new f/h !!! the 6803 bearings (if thats what the Quattro uses?) are about £5 each and all you need is internal circlip pliers and 3/8 socket set.

    You cant really knock the bearings out, clean, re-grease and refit.

    thanks, will check out now. No it's the front wheel. my zonda (which has barely been touched) is also a little rough too, so may have to do the same for that one

    hmm the guy in that video is using a spanner to remove part of the hub. I have looked and no option for spanner or allen keys either side. Someone mentioned a small circlip needs removing, but no sign of that either. the mystery continues!

    i had this on the rear twice. Replaced under warranty. When the second set went back i got different wheels. They would start off great then the bearing would get rough, only way to get them smooth meant there was play. Hope you get it sorted.

    MIne went after 8 months and went back to Ribble who sent it back to the distributor who took over a month to repair it, works fine now but from the research i did it seems the bearing seals in the hubs are one sided and substandard and not fit for purpose.

    Really put me off Fulcrum wheels, as I have had 3 sets of Quattros and all have had problems and have been sent back.
    Obsessed is a word used by the lazy to describe the dedicated!

    THREAD RESURRECTION!

    OP, did you have any luck with this? I want to put new bearings in my front Racing Quattro. The video linked above is for Fulcrum's and Campagnolo's lower spec wheels with 12mm axles - Quattros have 17mm axles and a preload collar.

    I plan to have a dabble this evening - should have a spare hour - and any pointers are welcome!

    Right.

    So this is useful for future searches. The end caps simply pull out of the axle - they're tight, with a rubber O ring - I started them with a flat bladed screw driver, prising them away (carefully) and then lifting them off the remainder of the way with a 16mm(?) cone spanner.

    Be careful, but forceful.

    Then unscrew the preload cap all the way, until it drops onto the coffee table. Watch out for the thin washer.

    The axle will then slide out through the opposite bearing - you may need to offer an "unscrewing" motion as the preloading threads pass through. Just to help it on its way.

    Knock out the bearings with a punch. Press the new bearings with - preferably - the proper kit. Refit the axle, preload cap, washer and end caps in reverse.

    Then go out in Soho. That's what I did, anyway.

    Sounds pretty staightforward and in Soho theres plenty of axle and bearing punch action too :) no video of that required ....
