Hi folks!

I just bought a pair of Hayes Superlite disc hubs (for QR).. From what I've told by the shop they've been sitting around for 5-6 yrs and are NOS. I think because of that, the freewheel makes nearly no sound at all, although it engages well (I suspect this may be a result of thinkened grease after all those years on the shelf?) And the front hub has a lot of resistance when I try to turn it by hand (I've read that this is common for these hubs; the seals may be a little too tight sometimes)
Do you folks recommend relubricating the hubs prior to use? Or leave them as they are??
And are these hubs the same as DT 240s' or Hugi 240's? Are there any differences between these models? Cause there is no service guide for Hayes hubs that I could find..

I'd very much appreciate any help..

Come on.. No opinions????

Hi, yes, those are Hugi 240's. (I know someone who distributed these a few years back) Very easy to do maintenance. No tools needed. There is a document available on DT SWISS' site I think. All you need is a vice, or a pair of VISE-GRIP pliers. Pull everything out, make sure you remember the sequence and correct side, clean, add grease and re-install. They are great hubs.

I had those hubs. They are supposed to be quiet, I really liked that about them.

When mine started to make more noise then I knew it was time to clean and regrease. DT has their super secret grease they recommend, if you call warranty dept in Grand Junction (ask for Dave), they will send you some, may not even charge you for it. I know, I've seen it.

You don't need vise grips, you don't even need to remove the cassette. Just pull on the cassette (really hard) to remove the freehub to service. Very easy to work on. Just clean and lightly re-grease. Too much grease and the ratchet will slip. (I know, I've seen it)

If I were you, I would not service them until they get louder. Build them up and ride.

Thanks for the reply. I downloaded the service guide for DT 240S hubs; I guess this is the one. I know that there's an expensive toolset for bearing overhaul; as long as I will not remove the bearings I may cut this without tools; but can I disassamble the ratchet mech without tools too?

Also in the service guide there's a Caution: "Never use normal grease in the freewheel mech, as this will impair the function of the star ratchet teeth, only use DT Swiss recommended special grease for this procedure." So what kind of grease should I use, I don't think I can find DT grease easily here.

And one thing I'm curious about; so the end caps and the freewheel rotor, they are just press fit to the hub body, is this so? No threads or anything?? You just grap them in a wise and pull out, right?

Thanks S-Works, that's good info. Yet, I have read complaints about the loudness of the Hugi hubs in another forum??? Anyway it may be best to leave the freewheel alone until I find the correct grease. (By the way, I'm not in USA, I'm from Turkey.. These things cannot be easily found here, I may always order it online but I'm not sure about the custom regulations with these liquid/chemical type of stuff.)

So let me ask you about the other issue; the front hub has quite a bit of resistance. It is not a scratchy grindy bearing type resistance but rather the smooth resistance of the seals (I suppose). I think a couple of drops of light oil may be good. But how can I access the seals??
