Campagnolo wheel bearing adjustment
Hi
I have some new 2008 Campagnolo Neutron wheels which are lovely but both seem to have picked up a bit of bearing play in the 500 or so miles I've done on them so far. It's quite hard to quantify the exact extent of the play but I can see the rear axle move (a small amount) if I 'waggle' it side-to-side. The front has a touch less play. Doing the quick release skewers up tight (not *ultra* tight, but pretty-damn- tight) is enough to take up the slack. Should I try to adjust the bearings? Cheers, mark |

If there is no play when the skewers are done up, then you should not need to adjust them. If you adjust the bearings so that there is no play when the wheel is not on the bike, then it will be too tight once you put the wheel on, and do up the skewer. Martin. |

Yes if you want the skewers slightly less tight. It's dead easy with these hubs, and can be done while the wheels are fitted. Do up the skewer to normal tightness. Find the adjusting ring on the side of the hub (HB-NE019*). This is locked with a small screw with an Allen head. With the same Allen key, unlock the ring and gently turn it clockwise a tiny weeny bit. It will feel stiffer as play reduces. Tighten the screw to lock the ring and test for play by pushing and pulling the rim sideways. Repeat until the play just disappears. Open the brake calipers to make sure the brake pads are nowhere near the rim as you test. If you think you went too far and turned back the ring to start again, any play may not appear straight away due to sticking. Give the end of the skewer a sharp tap or ride the bike over a few bumps, then test again for play. http://www.campagnolo.com/repository...on-UK-1006.pdf * http://www.campagnolo.com/repository...s07_C-0407.pdf - page 112. http://www.galeriecharmante.com/LadyCampagnolo.jpg ~PB |

That's right, but bearing adjustment is needed if the skewer has to be tighter than normal to get rid of play. I don't know if Mark's "pretty damn tight" is tighter than good. A bit of play can develop as the hub wears in, or shortly after it has been serviced. Mark, have the skewers as tight as possible *within reason*, then adjust the bearings if necessary. Get advice from a bike shop or other riders in person if you want a second opinion on how tight the skewers should be. That's something that can't be described over the internet. ~PB |
