Di2 Adjustment

[MrTickle]

Hoping someone could point me in the right direction.

I have a bike with Shimano Di2 groupset. When in the large cog on the crank, all gears are sweet as a nut. However, when using the small cog on the crank I get some clicking and occasional unplanned gear changing in 3/4/5th.

Anyone know how easy it is to adjust the Di2, or even better a knowledgeable Di2 tuning shop in the South Cheshire area?

Thanks.

Front mech is probably slightly out of alignment causing the chain to skip slightly

To adjust rear gears its a case of pressing and holding the power button on the leads up front and it goes into setup mode. You can fine tune the rear mech in tiniest of increments. You should be able to find full and easy to follow instructions on shimanos website. I can't remember every step off top of my head but it takes about 5 minutes to set it up from new and it is very easy to do. Does sound like it is front mech though

Thanks for advice - I will look up the manuals online
