I have a severely herniated C5 C6 disc and started with a very upright Trek 7200 4 years ago, as my riding improved I found that ride lacking. Early last year after many test rides I settled on a leftover 08 Specialized Sequoia Elite due to its more upright riding position even in the drops. Since purchase I have changed the saddle, pedals/shoes, shortened the stem and lowered the bars to the point that they are slightly below the saddle height. My neck has been fine, my rides are not that long <2hrs about 4 - 5 days a week. The improved control and more efficient riding position really do help make the miles roll by!
