Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

Disc or rim brake? If the former, then you won't beat this price:

pretty sure its disc, thanks for the info

I don't think the TT shifters are wireless, wiring a Speedmax is a bit of a mission. Good luck

Rival AXS derailleur
SRAM TT brake levers
New wireless blips
Shimano drivetrain

As I understand it you don't need the blipbox as you can just get the shifters paired once by your LBS

Does R8000 series di2 work with directmount rear hangers?

Best place/price for an electronic groupset?

Europe.

I can't remember the price difference but it was substantial when I ordered a Di2 GRX RD to my hotel in Germany before Mittliegeibeurg Classique (I think I've added enough vowels to cover any variations for when Schick turns up to correct my spelling).

Maybe this is old news, but I think the handlebar end integrated Di2 charger from Purple Dog customs is pretty neat, charges your Di2 battery direct from Dynamo hub.

SRAM Rival AXS help needed!

My rear derailleur has just stopped working. No signal to any connected device. No movement when I press the axs button. No lights. Nothing.

Battery is fully charged.

Connection points have been cleaned and cleaned again with contact cleaner. They are nice and springy and I can feel the contact being made when I install the battery.

Shifters are communicating with the app. Derailleur is not.

Was working fine until yesterday when, after a few dormant days, I picked up the bike and went out for a ride but with no gears. Components are out of warranty, though I have raised a ticket with SRAM helpdesk.

Does anyone have experience of this with SRAM or know of any fixes?

Have you tried a different battery/checked that the battery works in another derailleur?

Tried holding the AXS button while installing battery?

Depending which gearing option - https://www.sigmasports.com/item/Shimano/Ultegra-R8170-Di2-Disc-Groupset/10GPZ?s=1

Thanks @Jameo this button hold while installing battery approach worked to get the lights firing. However the derailleur now seems to be in a firmware update doomloop where it updates through the app but then immediately identifies itself as needing the same firmware update again. All the while being unable to connect to the shifters.

I am getting a di2 groupset, and considering the hope carbon seatpost, can I use any of the 27.2 seatpost mounts?

Even better, you can use a bit of bar tape

Will 12-speed 105 take a 40T cassette like 11-speed ultegra does?

Is there a 40t 12 speed cassette?

That is a very fair point. There does not seem to be one. 11-36 it is then

Another reason not to bother with 12s then.

You could possibly use a 12S MTB cassette though. Mmmm 51 toofs

Rotor make an 11-39

Is there a plan for shimano 12 speed 1x Di2? #buyer

They have said so yes but in the meantime rides of Japan has done it with one of those wolf tooth things that gives you extra cassette clearance

Spendy tho, isn't it... 331 euros

Thanks

For a disposable part like a cassette? Fuck that.

I was hesitant to even look up how much it is...!

from what i've heard yes, next year. all i've heard is that it will allow mix and match, but not exactly sure what that will entail. i didn't specifically hear it is 12s, that is just my guess, kinda doubt it will be 13s. no udh required.
