Jeff, nice idea, 33 mono on the front sounds good! I think you can also manage it in a simple way. Recently I tried to drive only the rear derailleur w/o mounting the front one: it works exept on the led consolle so, you wouldn’t have all the electronic features available I guess!
About the “chain-line”, no doubt everything would be easier and smoother

Hi Alessandro,

Great work. I run a one-by-ten setup on my mountain bike. It’s a 33T chainring up front, and a 10spd 11-36 cassette. If I were doing the di2 conversion only for the rear der, in keeping with the one-by-ten setup, would less modification be necessary since me overall chain wrap is much lower than two-by-ten road/mountain setups?

Thanks!

Hi Ivan!
Presently we are riding with: 27-40 Front & 11-34 Rear. For realizing this capability, we modified FD e RD. It’s not so easy, but you can do it. It works really fine! Now we are confident for shifting up to 11-36 (!!): here on my desk I have the Shimano cassette sprocket, I will do it soon Then, you are right: SW7970 are the best buttons for managing the system! But, also here you need to modify the connection with consolle system…anyway, I have some pics on our Facebook account http://www.facebook.com/media/set/?set=a.122886834452110.24715.110107649063362&type=3
Ciao, Alessandro

Alessandro,

I see on your website a Mountain Bike with DI2. Can you tell me witch serial numbers of the Shimano parts (SW7970, SW7971, ST7971, ?)you used for changing the gears in font and behind.

Maybe you can answer on skater007@scarlet.be

Thank you very much.

Hello Allesandro,

Does the DI2-system also works with another speed cassette, for example the greatest toothwheel with 32 tooths or must it be the standard cassette with maximum 11-27.
Thanks

Here in Italy we can do it
1 & 1/2 year off-road test, races, mud, powder, whatever…no problem! Electronic shifting system is the answer. You can have a look on our website! Cheers

@sami srour, The second Di2 Mountain Bike that we did for Interbike 2010 did use the Di2 remote shifters and has since become common for all of our Di2 MTB conversions. This bike was built before those were available and we custom made the shifters.
