D Series Hubs on 8 Speed?

Recommended Posts

stevebo

Has anyone modified (shortened) a set of D series hubs to fit on an 8 speed? Is the keyway the same width?

I have never owned any D series hubs. All other hubs use a 1/4" key. Chiming in to get my learn on.

My friend VinsRJ just sent me the measurements of an 8 speed hub to a D series hub

 

8 speed is 5 lug x 4 1/2" 

D series is 6 lug x 6"

 

It was suggested that I try and source a wheel adapter but not sure where I can find that conversion.

D series has 1/4" key but it is an #RX  very odd length and height ratio.

I don't think anyone makes a 5 to 6 lug adapter.   Option # one would be to go with the "D" hubs if that is the size wheel you plan to run.

Option # two would be to have a set made at a machine shop, but that would be too expensive.

The key for the "D", GT-14 and 953/1054 is an odd one, but you could use a piece of 1/4 X 1/2 flat stock to make your own. Your C-195 probably has the same hubs and keys as the "D".

  Key is #RX  I have some if anyone needs them.

It'd be easy enough to cut another keyway into the D series hub to match the 8 speed axle assuming you have the same diameter axles if the keyways are indeed different.  Cutting down the hub on the non wheel mounting side wouldn't be an issue either with the appropriate machining equipment (or a grinder depending how "finished" you want the product to be).  That is if your intended purpose was to be able to run a D series wheel.

Just keeping in mind a set screw should be added to where the new key is cut, that’s a great idea!

No need for new keyways...all involved here are 1/4" wide.
