The Specialized Command Post lowers the saddle height with the push of a button. Initially I only used it for really technical courses, but now its a permanent fixture on all my mountain bikes. It lowers my centre of gravity, gets the saddle out the way for a better body position in the corners and drops, and on a few occasions I’ve used it for a (safe) really aerodynamic tuck.

I think this “drop seat post” will eventually become more and more prevalent amoungst Cross Country and also social riders. Once people realize weight is not everything, learn how to use it properly (I’m still learning proper cornering) and once they’ve made peace with the “funny”  look and feel. Remember when 29ers were “funny looking”?
