6800 hubs specs?

phcollard · #1 09-11-2013, 07:28 AM

Greetings folks!

Any of you has the specs for the Ultegra 6800 hubs? I'm looking for the usual suspects : flange diameter, center to flange, spoke hole diameter.

I did a search but I could not find them. Even Shimano hasn't listed the specs...

Thanks a lot and a great day to all.

Philippe.

Thanks Peter. Sounds logical that they should be the same as 9000. That would be great if you could report

I was planning to build a wheelset with 6700 hubs and I already have the spokes. Do you think I can use the same lengths for 6800?

Here's what I got :
NDS : Sapim Laser - Silver - 285
DS : Sapim Race - Silver - 284

Thanks again

so what's the deal with 6800, are they going to offer disc versions of the hubs too to go with their new (stupid) road discs?

I called Shimano USA customer service earlier this year and they were able to give me all the specs on the DA 9000 hubs. 949-951-5003

Nothing special Nick. I just figured out that if I'm to build a new set of wheels I'd better go for the 11 speed hub straight. No plan to upgrade in the coming months but with me you never know

Don't think it makes any difference but 6700 RH rear hub ctr to flange is 18mm...with 11s and assuming total distance is 130mm...think RH ctr to flange is less than 18.75mm.

I measured 17mm. Very similar to Record hubs..

The numbers I gave were for 6800 hubs. Flange distance is 56.9 with a 9.7 Dish.

Yep, I know. My point is that 6700 rear hub(10s) is 18mm RH ctr to flange,on 6800, with 11s and keeping 130mm spacing, I just don't see how the RH ctr to flange could be higher..with a taller FH body on it, with 6800.

My employee just built a set of wheels with 6800, he measured and wrote the numbers down BUT like I said, for spoke calc, it means little.
