What is the brand/model # of this freewheel hub?
 
1 Attachment(s)
Hi. I'm trying to find out what is the brand and model number of this freewheel hub... There is a few numbers and "codes" on it.
On the metal body : Go
On the rubber washer near the axle : KOK 0049C 156
Any idea what is it? I want to us it to rebuild my rear wheel.
Thanks

You can simply measure it for your spoke calculations. http://www.jensonusa.com/help_desk/t...e_help.htm#hfd

Thanks for the link. Very helpful info.
Do you have any idea what brand and model it can be? It supossed to be a Shimano hub, but I'm not sure

Sorry, not enough info for me to provide an answer on that.

If it were a Shimano hub, it would say so somewhere on the shell and bearing dustcovers. I've never seen a good quality hub by a well known maker that didn't have their name on it rather prominantly.

It's not a Shimano hub- Shimano would be a cassette-type "freehub". Yours is a freewheel type.

It's almost certainly a basic Taiwan-made hub. It doesn't really matter who made the hub- it's the dimensions that matter if you're rebuilding the wheel. If you're using a spoke calculator that uses dimensions from stored data (like Spocalc), choose a basic Shimano small-flange rear hub. I bet the spoke lengths come out fine.

I agree the hub in question is not by Shimano but didn't Shimano make freewheel hubs "back in the day"? They didn't start making hubs when the freehub design appeared did they?

Just measure the spoke hole diameter, it a black generic shiny hub,
leave it at that. are the bearing surfaces decent?

or if having a brand name hub is important, get a different one.

FWIW, a shifting of axle spacers, will center it for single speed freewheel use..

Then the spoke length would be the same..

They did indeed make freewheel hubs.

That one has the hub shell shape of a Shimano Parallax hub and I have a weird feeling I have an STX-RC Parallax that is a 7-speed screw on freewheel. I'd have to run up to the shop to confirm, however and I'm pretty sure it's gotta be a freehub.

The vast majority, if not all Parallax hubs were freehub, though.

All STX rear hubs are freehubs.

That sounds about right to me. I dunno why I have a feeling that one on the bike at the shop is a freewheel. Probably because it had a freewheel wheel on it when I drug it out the trash. Put the STX-RC wheelset on there and didn't pay much attention to it.

Looks like a Formula hub.

LesterOfPuppets 05-26-11 10:12 PM

I've an old Formula hub that looks really close. It has a little ledge on the bevel, though. I wouldn't doubt that a couple years later Formula got rid of the ridge and had a perfect Parallax copy.

FastJake 05-26-11 11:00 PM

It does look like a Shimano Parallax hub, but I don't think it is. I've never actually seen a Shimano hub meant for thread on freewheels since the cassette Freehub took over in the late 80s. And that hub isn't from that time period.

I agree with the above, it's just a generic freewheel hub.

Does the skewer say anything? That could provide your answer.

lopek77 05-26-11 11:42 PM

Shimano still makes freewheel gears... Specialized is using it on some of their bikes.
This freewheel hub supposed to be a Shimano brand, but I have my doubts...
Skewer is not original one... this hub was used when I bought it.

Yes, Shimano does still make freewheels. They do not make freewheel hubs anymore AFAIK.

Not a Shimano hub but you can use data from any of the Deore series hubs that are spaced at 130mm

Of course they made freewheel hubs!

Well, yes, but they stopped making freewheel-type hubs by about 1988. By then, cassette hubs were definitely superior for 7 (then 8, then 9, then 10) speed clusters. For a couple years Shimano made Santé and Dura-Ace 7-speed freewheels- but they went away when Dura-Ace went 8-speed.

Assuming it's a 135mm rear:

Just plug:

45mm flange diameter
33.5 left offset / 19.50 right offset

into a calculator such as SpokeCalc or mine at http://www.mrrabbit.net/wheelsbyflemingapplications.php (grab the spreadsheet - see Joytech under spokechart tab - it's close enough.)

thanks !

fietsbob 05-31-11 02:58 PM

yea, Freewheels always had a little side to side motion , of the cogs, as they rotated.
hard to get precise enough at market priced returns.
kind of like planetary orbits..
which was never a problem for Friction shifting, and wider spaces between cogs.
but was a problem for the pre set nature of index stuff
flat cogs , on freehubs was easier to get some of that out.
