Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

Well, I did the last four days of last year's Mallorca trip using only one gear - 34x17. And that included Sa Calobra and Puig Major. So why not? Makes life more interesting.

It helps that we only really do the mountains. Any long sections would be a bit spinny with that gearing.
