Brilliant frame. It's the one I've just broken, had it ~5 years.
How did you break it? Full carbon isn't it? You able to have that repaired?
Ah now thats an interesting dilemma I've just given myself. Do I drop the Di2 and get a power meter...?
I wouldn't drop Di2
I'd love to have it but currently its worth about the same as my actual bike haha. 2-3 years when I upgrade ill be considering that.
Looking at getting out a few times in the evening through the week, but short of ideas where to go!
My advice would be to take off. Once you get out you'll find routes you sana take, just set off and keep going

I have about 8 routes I take to work ranging from 9.9 to 24 miles. I have loads of ride info out side of work, either on the roadie or mtb.
You'll be amazed at how many ideas float into your head once you set off, and if you dont know any loops when you get far out just turn around and come back the same way.
