Tic/Tinkle Noise From Loose Ball Hubs??
Ed Ness writes:
I have a low mileage set of Dura Ace 7700 hubs laced to Open Pro rims. My rear wheel rolls nice and smooth but emits a non rhythmic "tic/tinkle" noise as the wheel spins. This noise occurs regardless of load and it even occurs if I spin the axle while holding the rim stationary! The noise seems to be coming from the loose ball bearings as they bang into one another (Dura Ace hubs do not have a cage to space the balls apart from one another). Repacking the hub with grease reduces the noise but it always comes back after a handful of miles. This particular wheel has made this noise since new. I know the noise is in the hub so please don't say this is the "Open Pro Click". I adjusted the cones so when the wheel is clamped in the frame there is no side to side play at the rim. -snip- wrote: By the way, bearing cages cost nothing in performance while being a great convenience for maintenance. That way the balls come out as a unit and go in that way even without grease. jim beam wrote: are you advocating the use of a bearing cage for cup & cone axles? if so, it shows that you've never actually serviced a wheel bearing contrary to all your "expert advice" on this subject because if you had, you'd know that it would be impossible to get the bearing balls in or out if they were held with a cage. There are plenty of hub designs which ship with caged balls, from XMart steel hubs to Campagnolo's new "big bearing' hubs. I haven't seen any inherent issues - that can be done well or badly. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

er, even that pathetic straw clutching exercise supports what i've been saying. the fact that the [shimano] dust cap gets damaged on removal /requires/ an aftermarket replacement. as you'd know if you'd ever tried. That is *also* an *exception to the rule*, which is why people *mention it explicitly*. For ****'s sake. Jasper |

I haven't seen any inherent issues - that can be done well or badly. there's absolutely nothing wrong with bearing ball cages - they're used in countless cartridge bearings all across the planet, bottom brackets, headsets, etc., and work just fine. the question was whether you could retrofit a loose ball hub with them to stop the noise... |

No, wait, that's not all. Read what you quoted from JB. Did that ? Then read the lies and exaggerations you composed (words carefully chosen, and you can't escape the facts of what you wrote right here). Geez, it's hard to figure who's got it in for whom here.
