Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

Are you going to run a cable from RD all the way to the Junc A? Otherwise Junc B or something needed.

downside to buying older 11s stuff

Might need firmware update, battery life might be reduced, might be missing features but these issue for a TT bike unlikely to matter.

Nah nothing practically useful for TT purposes unless you need to know in real time what ratio you are pushing or if your battery is about to conk out during a 12 hour event.

Annoying ain't it? If everyone stopped paying > £30 for them on ebay I'd crack one open and find out what's special about them.

In which case, is anyone selling any of the items I need? Can be a shit condition as long as they work.
I was planning on putting a seat tube battery in the extension if it will fit.

I'm new to Shimano, I've only had 105 10 & 11 speed groups briefly. But yes its annoying.

Right well I should probably look for the rest of what I need.

I have ultegra shifters and RD, seatpost battery. Need everything else.
Does the bar end box replace the under the stem doodah?

Does the bar end box replace the under the stem doodah?

Yeah, that's an alternative charging port/status indicator boxythingie. I was going to get one for looks but prefer the stem box for function.

Wrap capacity question.
Is the wrap of chainrings 46/34 , cassette 11-36.
(46-34)+(36-11)= 37

Yes.

Bugger wifli has a wrap capacity of 36

wifli has a wrap capacity of 36

Cut the chain to allow you to use 46/36, so even in a panic you don't rip the dérailleur hanger off. If you accidentally engage 34/11, no great harm will be done.

So I should be ok?
Would a better idea be just to get a 36 inner?

So I should be ok?

Yes.

Ok thanks.

An additional comforting thought I’ve just had.
Wifli is for 32t. Given the obvious pairing is 50/34 the wrap capacity of that would be 37.

I was just looking at the new fields now I have power and I saw the gear change field.
I made 627 changes over 90km.
Seems pretty high but I have no point of reference
And here is the elevation profile,

1 Attachment

I think it counts each cog as one shift, so if you drop down a half at the rear, that counts as 5 changes.

I feel I shift more with Di2 which I think is a good thing. More often in the correct gear, I find I do more front shifts in particular.

Yeah I think I might have been shifting a little more, also new wide cassette probably factors in.

Anyone know how to change the gear set up on the gearing fields on a wahoo?

Does anyone know if I can run a 1x setup with:

R1960 bar ends
1 X R600 climbing shifter
3 port

Everything I've read says you can't use spring shifters without a 'brain' but can't see why the above wouldn't work (plus the usual connections to the junction box and battery)

r600 pave shifter is a proper etube device, whereas the sprint shifters are just peripherals for the brifter not having their own transciever.

So therefore the above should work with a 3 port?

I'm running an r600 into a 5port to a 6870 mech. No other shifters.

It would, but you'll need another junction box otherwise you won't have a port for the cable running to the rest of the system. A 5 port might be a neater solution, otherwise you'll need an extra junction B box to connect the shifters.

Ah yeah good point! I guess a Y connector between one bar end and the climbing shifter would do that job as well, means a lot of internal wiring planning though. Cheers both.

My plan is to get a climbing shifter over here in the US where they are slightly cheaper and start taking it apart to see how it can be paired with magura brakes. There are a few tutorials out there but all seem to still end up with pretty agricultural results.

Been there, done that. My P5 has Magura hydro brakes, a 1x setup, and twin base bar and extension shifters all driven off a very hacked R600 shifter. Let me know if you want more details...
