|not super retro... DA 126mm hub Q||damon|
Nov 6, 2003 4:53 PM
|So i have an (almost) NOS DA 6sp hub sitting here that has only been laced up, never ridden...
I was trying to take it apart so i could see what kind of interface there was between the freehub and shell, but then i found it is not the typical 10mm allen. Looks like a funky spline.
So, my question to you all becomes (and i think i know the answer to this):
Are different freehubs (preferably an 8/9sp friendly version) compatible with this older DA hub?
If not, does anybody collect these things, because honestly, i don't have a use for it, then...

|Dollars to donuts you're looking at a freewheel.|

|Seeing as how i'm currently without job, i'll take dollars, thank you! :-)
126 over-locknut dimension, uniglide freeHUB body, and when compared to a shimano DX freehub (37mm), is obviously shorter (31mm) (ie. can't hold 7 gears, so must therefore be 6).
My campy super record hub on the bianchi has the freewheel...

|When in doubt, Sheldon Brown has the answer
Shimano TL-FH10 $16.95 For removal of 1996 and earlier Dura Ace freehub bodies. Its a park tool.
1996 and earlier (6-, 7- & 8-speed) Dura-Ace Freehubs require a threaded body, the aluminum hub shell has matching threads. This system is not interchangeable with anything else, but they are all interchangeable, so you can upgrade from 6 or 7 speeds to 8 by installing an 8-speed body.
This is a rather expensive part, but if your wheel is in good shape, this can be worthwhile. With the new body, you'll be able to use any 8- or 9-speed cassette that doesn't include an 11 tooth sproket.
You'll need the special tool for this, TL-FH10. If you buy the body from us, we'll lend you the tool, which is only used for removing the old body.
1997 and later (9-speed) Dura-Ace Freehubs have a spline attachment between the Freehub body and the aluminum hub shell. These use a hollow 10 mm Allen bolt to hold the Freehub body to the shell. This same system is used for all non-Dura-Ace Freehubs (with the exception of the "Silent Clutch" models.)

|Absolutey, sheldon brown... that site has a crazy amount of information.
Thanks for pointing out the (almost) obvious! :-)

|You can only change it to the uniglide 8 speed body that takes a thread on outer cog. The splines are equally spaced, so you would have to file a hyperglide cog to fit on one of the first 7 positions.
Don't bother, it's not worth it. I've got a 7 speed version of the same hub, and was thinking of converting it, but it just wasn't worth the effort.

|Its a shame because it is a buttery smooth hub, but for the (at least) $70 it would take to convert it, certainly not worth the hassle.
Stupid Dura Ace :-)

|The 8 speed HG body will fit onto *ANY* pre-1997 Dura-Ace hub, from 1978 Dura-Ace EX to the 1996 DA 8 speed, except for Direction-6 (ie DAAX or DAEX with the funny flanges; 1982-1983 only). I can vouch for this from personal experience.
This means that any 8, 9 or 10 speed HG cassette can be fitted - 11T cogs require a 1mm spacer or a little grinding - see sheldonbrown.com...
The only reason you may not want to do it is the cost of the DA freehub body, but they are reliable; I'm still using one from 1991. It may be easier to get the matching RH cone so that the dustcap fits exactly, but if I remember correctly the existing one works okay. The axle is generally long enough too....
