Rear Hub Question - 87 Nishiki

Hi Everyone -

It seems like after 28 years of service, the rear hub on my 1987 Nishiki Prestige could be due for replacement. Wheel seems to spin ok, just not quite as freely as I would like and I'm just getting a bit of noise from the back that I've isolated to the hub. Bike certainly still rides fine, so I don't think I'll replace it immediately, I'm just thinking ahead.

Anyways, this is my first classic/vintage ride so I'm not sure if I can replace the hub with a modern one? Or do I need to hunt around for some NOS replacements? If I can replace it with a modern part that at least looks period correct, then obviously I'd like to go with that.

Thanks

Depending on your frame's inside width, how many speeds (shifter) that you would like to use, a period-looking (i.e. skinny barreled) hub might end up being an actual vintage hub.

Shimano's freehubs, even their lowest HB-RM40 and the like, are very durable and can give very long life. 7s versions are plentiful at bike co-ops, and really cheap when/if the rim is in bad shape. Both 32h and 36h are common.

Getting up to the old DX level (mtb, touring) and Ultegra level (road) versions, seals are first-rate and the bearings very, very smooth.

I dread the day that such hubs become hard to find, so I try to keep a good stash of them on hand.
As of 1996, with introduction of 9s gruppos, Shimano's freehubs eliminated the stepped bulge in the hub center and made all of their top-level (105 and better) hubs lighter. Their mtb hubs had grown fat centers by this time however.

As for your Nishiki's rear freewheel hub, you will need to remove the freewheel and axle in order to diagnose the problem. A broken axle, cracked bearing cup or disintegrating cones or balls could all be factors in a noisy, rough or loose turning action.

^ Thanks for the response. I can dig into it further to verify the issue, just something I noticed the other day.

The bike uses a 6-sp cassette, and it appears to have a Sansin rear hub.

i'd assume it's a freewheel, not a cassette. and you're sure the noise is from the hub, not the freewheel?

have you rebuilt the hub with new grease and good 1/4" bearings? in what condition were the cups and cones? is the axle straight?

Ah yes, it's a freewheel. Sorry for the confusion. The hub has not been rebuilt. I assume anyways, bought it from an older guy who kept it indoors most of its life. The noise that I am hearing almost sounds like one or more of the bearings are knocking around a bit. No play in the wheel, everything seems straight. Is there rebuild kits available, or do you have to more or less piece them together yourself?

Look up hub overhaul on YouTube, and do it yourself. Use new bearings, check the races, and cones, and use alot of grease.
Cheers

sheldon brown is your friend.

buy $5 park cone wrenches at your lbs.

overhaul the whole bike while you're at it.

by '87/'88, lots of hubs were cartridge bearing, not loose ball. if so, let an lbs remove the cartidges. you can install and adjust the new ones yourself using a big socket from your socket set and your new cone wrenches.

if the axle is bent, buy a new one online ($15 or so), or get a good used one from your lbs/co-op.
