Durability of DI2 ?

[kingrollo]

I have had ultegra di2 for 6 years now. The shifting is totally sublime - I absolutely love it......

But......

I have had to replace the following components:-

1.Battery (warranty)
2.Shifter - started leaking £200
3.)Front Mech £215

Is this typical ? - I only do about 3k miles per year - and use a winter bike during the winter.

Seriously thinking of mechnical 105 for my next bike

Any experience welcome

Well I've had my current bike with 105 mechanical (11 speed) for 3 years now (almost), having done about 11,000 miles, and (not counting crash damage), I have had to replace one shifter and one rear derailleur mech. Plus of course cassettes and chainrings, but those are the same for di2 or mechanical. I have also had to replace one front and two rear derailleurs due to crash damage.

But they are cheaper to replace than Di2 stuff.
