Lacing Dura Ace hub

Hi,

I'm having difficulty inserting the Sapim Force spokes into the Dura Ace hubs. Any tips or advice would be welcome. Thank you.

Is this a new hub or relacing an old one?

So are you saying the HB and FH 9000s? Or that the hubs (of whatever model version) are new. New is only in not yet used, not specific to a version.


But to try to better answer your question. The only DA spoke hole diameter spec I found with a bit of searching is from the Spoke Calc spoke length spread sheet for the 7800 series. This suggests a hole which is smaller then most of the other Shimano hubs use, at 2.4mm VS 2.6mm. Still one would think that a 2.4mm hole will accept a 2.18mm spoke.


This only shows how poor published data is when compared to in hand experience. Either you are not inserting the spokes ina manor that will work or the spokes are too fat for the hole. take your pick. Andy (who now has used up his 3 posts per thread guide line).

Thanks for your help. The hubs (DA 9000) and spokes have never been used, brand new out of the box. The shop where I bought the components replied that they've laced that combo many times and I just need to force the spokes in. I'm just worried of scratching the hub or bending the spokes.

The Shimano book shows that hub also being available in an Aero spoke version.
Are you possibly using the incorrect spoke/hub combo?

Why the triple butted spokes?

In MOST cases, the thicker bend fits the relatively larger sized hole in the hub "better".
As Andrew mentioned, typical Shimano hole size is 2.4 or 2.6MM The 2.14MM bend is "less sloppy" than 2.0 or 1.8MM spokes.

Once you bring the spokes up to tension there is no problem.
