Ultegra update?

[pdlpsher1]

Is the r8050 also available as well now?

I haven't found any online.

Starbike shows to have the short cage R8050 ready for dispatch. I emailed them and they confirmed it.

Good news. I'm in the U.S. so it might take just a bit longer to get here. I spoke to a large mail order shop in Boulder and they told me 'any day' now. I need the RD-8050 GS long cage derailleur. I already have the new 11-34 cassette and I need the Di2 derailleur to go along with it. I use the 11-34 for special use, one day climbing rides that have lots of steep climbs.

Nice. I want to replace my R785 shifters. Deciding between the 8070 and the 9170 levers.

Another U.S. based online retailer is showing availability on Sept. 19.

You do, unless you want to skip B and run cables from the drifters to the bottom bracket

Does anyone know how you determine the length of the wires you need when you upgrade to di2?

A tends to be at the stem, B tends to be around the bottom bracket. Battery is often in the bottom of the seat post. You can take a soft tape measure and roughly figure out what the lengths should be. If internal, then round up a bit, since

Planning to upgrade st-rs685 shifters with the st-r8020 ones. Dealers manual showing need to use Funnel Adapter. But from the picture it doesn't look all that necessary. I want to make sure that it's really needed as I have trouble to buy it. Bike24 isn't selling it yet (getting the shifters from there).
Can anyone confirm it? Thanks.

Anybody know of any carbon rear derailleur Cages available to cut down on weight a little?
Or any other part out there to cut down overall weight?

(Please don't reply "buy dura- ace" haha)

The funnel adapter should be included with one of the shifters.

Hope you are right. That would be great. I was looking at some package informations to Dura ace shifters and it wasnt mentioned. I was actually planning to get the shifters first and then to get the adapter if its actually needed.
Thanks for the heads up!

Why not? That's the only answer that does make sense imho.
