Which Groupset?

The 11 speed 11-25 cassette is very nice as a 'one cassette to rule them all' road cassette, together with a 50/34 compact.Good balance of range, and jump size.

Thinking of going 52/36 next year. It'll be a smidge better for my usual road biking. Not sure if the extra 2" at the low end will require a climbing cassette for hitting the mountains. My initial thoughts are HTFU.

No we are talking.
