>>1785412I had the same dilemma when I bought my first "real" pair of wheels last year. I ride in PA so no Pikes Peak or Alps style climbing. Just got some 50s. Definitely happy with my choice. Definitely don't want anything more than that unless you're doing some serious TT, but something a little less wouldnt be bad either. 50 is just a pretty easy depth to find a good deal on
