What type of grease should I use on my record hubs..(23 posts)

What type of grease should I use on my record hubs..jimijoe

I have 2001 Record hubs with the "greasing hole" that are due for some lubracation. What type of grease should I use? and How do I inject into the grease fitting??

I am using Perdro's greese injector and the greese that came with it. Seems to be just as good as the original stuff.
May switch to something a bit thinner next time.
Don't do this!!!!Kerry

The "grease hole" in Record hubs is for oil, not grease. This is used for time trials and one day events when you have guaranteed good weather and want absolute minimum bearing friction. If you inject grease in there, you fill the entire channel between the axle and the hub body with grease. This means lots more friction! If you can find a really light grease, then you would reduce the friction, but then you would not have a good quality grease in the bearings. These hubs are so well designed, that you should be able to repack the hubs once per year and never need the lube port. The only reason for more frequent re-greasing is if you get caught in the rain a lot, and you should still do this the old fashioned way.

I read on other sites - including Campy's - that its' OK to inject grease into the port. Hence the "grease port" moniker. I did it for the first time this afternoon. I bought the Pedro's grease gun for my front Am. Classic hub that has an actual 'grease port'. AC rec's injecting grease after every rainy ride and/or 2000 miles.

I hope you're wrong. The last thing I need is MORE friction. Paul

He is right on all counts. Avoid greasing the port.

Ya know,it just sucks when the manufacturer, who builds and designs this stuff, just can't get it right. I mean, why put it in the instruction guide and all if you aren't supposed to do it.

It's just like those truck designers, they put the tailgate on trucks when every one knows it increases drag. Now I have to look at all the brainiacs driving around with the tailgate down.

Good thing you guys are around to set us numbnuts strait. Jeez, I am gonna just chuck this crappy Campy stuff and get DA.
So you believe???....C-40

The unqualified postings on this site, rather than the factory literature? If Campy says it's OK, then it's OK (I haven't read their official stance). It makes sense that injecting grease would increase friction, but by how much? If it adds two seconds to your next 2 hour ride, are you going to care? I'd try to quantify the problem before getting upset about it.
Campy says OK...C-40

The campy hub instruction sheet says it's ok to inject grease. I'd beleive them.
Campy says OK...So it's OK with mePaulCL

I did it and I'll do it again the next time I get caught in the rain. The mechanic at the LBS said OK too.

I agree...who ya gonna believe...the manufacturer or hearsay.

No of course I don't believe them, I was being sarcastic. Hence the reference to tailgates on trucks. Just another example of people second guessing based on hearsay.

1) It won't hurt your hub and it is a way to grease things, it's just a high friction alternative to the traditional way of lubing a hub. Campy doesn't have it wrong in the sense that you can grease your hubs this way. But the oil hole was originally developed for (guess what?) oil, and that is what it is still best used for. Campy's top hubs have had this feature for well over 30 years, but it only became a "grease port" recently as a way to make their hubs easier to maintain.

2) According to the aerodynamic research done by the car companies, and referenced by that authoratative source, the Car Talk brothers, pickup trucks are actually more aero with the tail gate up because of a cleaner disengagement of the air flow from the back of the truck. More aero still with a bed cover installed. But who could give up selling all that aftermarket tail gate junk by telling people that it does more harm than good.

I know that you know this, but I thought it proper to add that when the oil hole is used for grease the grease takes the path of least resistance. This frequently causes the freehub pawl and ratchet area to fill up with grease. One good benefit is the reduction of pawl noise when coasting, but it may also make the ratchet action unreliable. The old Campy Krystal grease was really nice for hubs but they discontinued it for some reason. I have been using Rock and Roll Web grease. It really seems to coat the balls and races very well and is still doing well after a year. Campy hubs do not have the best water resistance and should be cleaned after a ride in hard rain, or a wet ride in a pace line. The spray off a close wheel will really flood anybodys hub. A ride on a roof rack in the rain is pretty rough too.
Doesn't the oil wear out very quickly?Sintesi at home

I know this is an older "trick" to get the bearings to roll faster, but how soon should you re-oil? I understand you can burn your bearings out rather quickly if you don't stay on top of it.
One-time dealKerry

The only time you oil hubs is for special events, most typically a time trial or track event. If you knew the weather conditions were good, you could consider it for a single race, though the advantage of lower friction is much less in a mass start event. You DO NOT continue to do this, as your hubs won't last. Oil for the event, then repack with grease until the next event.

What do you have? I'll take it.

Gee I think I'd worry about the gram of grease I added before the added friction.
Don't do this!!!!Bennnny

DO NOT put oil in there, these hubs are very well designed in deed but they are a piece of crap. The bearings are to small and they wear out very fast. If you want to do something good to those hubs, put some very sticky grease because the plastic ball retainer washes the grease off the ball bearing, or put the ball bearings loose in the hub with 3 more. So there will be 18 ball bearings in the hub.
Too much friction coming from the grease???MrCrud
Apr 28, 2002 2:11 PM
Come on!! Maybe when you use grease instead of oil, the axles feel slower when you turn them by hand, but after a certain point in a ride, the temperature warms up in there and the grease gets a lot more liquid. On a bike, it's very hard to feel this, but on rollerblades it's very noticeable. I agree light greases work better for hubs, but by so little that it should be of no concern to anyone but the most anal-retentive racers ( no offense if there are any of you here ) Everything is relative. There is also the point of diminishing returns. Just how much regular maintenance are you willing to do to have that little difference in friction ( in the unusual event that you can actually feel it when riding )??? Only using oil for bearings, especially for bike applications is very very hard on the bearings. Anyhow...just my 2 cents worth

Greatly increased grease friction. There had gotta be some kind of award for that one! Bwahahahahahahawhawhawhohostoppidpleaseyourkillingme....

There is indeed many circumstances where the wrong or too much grease can cause increased drag in a mechanism. I have had to remove grease from machines that were closely power monitored to prevent overload limits from knocking the machine off line. These machines had a lot more latitude for drag, than our spindly little legs. Sometimes what seems ridiculous, is not.
I understand what you mean....MrCrud
May 1, 2002 7:29 PM
But you also gotta take into account no one is gonna use greases like high-pressure Moly grease or stuff like this for hubs. Any bike, or even simply bearing, oriented grease will not be a factor. Period. I know how sensitive some machines can get, and that's why there are so many types of lubricants out there, i just dont think it applies to us cyclists, unless, as i said earlier, you ride at 100km/h for a few hours straight...

You assume the average bike rider can understand the differences in lubes. Wanna buy a bridge? You might be surprised to see what I have seen used, "grease is grease, right" he said. Not eggzackly, I said.
your right......MrCrud
May 2, 2002 6:14 AM
....assuming is my big mistake, but i base all my argument on common sense, which seems to evade a few ppl...You do agree that for bike applications, the need to reduce the frictions coming from the lubricant ( bike oriented lubricants ) is ridiculous!!! Anyhow, enjoy the riding!
