Shimano Di* do and do not.

I treated myselfIs there anyone doing an aftermarket conversion to the internal battery?Would look so much better.

 

[Mr Haematocrit]

Is the Roubaix Ui2 (ultegra) or Di2 (dura) and is it 10 speed or 11?
Looks to be ultegra 10 speed is that correct?

 

[grumpyoldgit]

Di2 10 speed.

 

[Mr Haematocrit]

You can approach the seat post battery in a number of ways.
There are after market battery products available which are listed in this thread a little earlier or y

ou can do a DIY option, the Di2 battery is 7.4v Lithium Ion battery and you can replace this using many options, some people use nicad cells packs available from radio control model stockists.​

Alternatively you can run a custom battery pack. You can see the battery for my Venge in my album.​

I fit seat post conversions to my own bikes and for other people. I am working on a new battery setup for my Tarmac which is similar to the Roubaix seat post. I would be willing to share details with you if your interested, I won't be building the battery pack till the new year though.​

I would be very interested in that,thanks.Me & electrickery dont mix too well

V for Vengedetta, have you seen anyone who's managed to graft a triple chainring into a Di system? I'd really like to use Di on a recumbent but I simply can't get the gearing range required with a double chainring setup.

I have not seen one myself or am aware of anyone who has a working system with a triple.

However K-Edge with their conversion have modified a setup for mountain bikes, calling it Ki2 -- they adapted the derailleur by custom designing a new, longer pulley arm. Something such as this may get you the throw required to clear a triple.... I have no evidence that this is the case, its just a theory.​

You may be better in all reality looking at something such as diyshift.com and making a bespoke solution. Diyshift basically uses radio control model servos on standard components to do the shifting.​

Di2 10 speed.

Grumpy are you sure it looks like Ultegra to me not Dura

Not an expert on these,but when it says Dura Ace on the levers,front & rear derailleurs,my guess is that it is Dura Ace.

 

[ziggys101]

Ok just looked too big :-) my bad

 

[grumpyoldgit]

I have never seen the two side by side,so I couldnt tell.

Go to jail,do not pass GO

I continue to run the optional sprint shifters on my Venge and I have also equipped my Tarmac with the climbing shifter which you can see in the image below, It serves a purpose if you ride up top a lot of the time.
