Di2

[Chislenko]

Being a bit of an old f--t I have traditionally sided with "older" technology.

However, just bought my first bike with Di2 and I flippin love it.

I may not love it if it goes wrong mind but for ease of gear change it is top notch.

A lot of folk love it, but I know of a few people that have had issues (rear mechs) and they are an expensive replacement if they fail.

I have Di2 on my bike, it's superb.
Is it necessary? No but as and when I get a new bike I'll definitely have Di2 again.
My Canyon is 8 years old and only issue I've had was earlier this year the front mech broke through metal fatigue so could have happened on mechanical after so long.
Got second hand one off eBay for £50 and it's like new.

I update by bike to Di2 last year absolute love it ,there's just something about the feel of the gear changes to mechanical that you can't quite explain but people who have changed just know ,also love the syncro change when dropping into the little ring so you don't get that massive jump in gearing , Agreed it's not required but it's certainly nice to have .
