Im in a dilema at the moment! Im after an adjustable seatpost with a layback and a 27.2 diameer but the only one I can find is the ks i850 which is cheap but has a large weight penalty compared to others. My thought is to get a lightweight saddle perhaps the tioga d spyder, which might not be the comfiest but the ks i850 also gives a small amount of suspension for added comfort. Any thoughts on this? anyone had experience with either the d spyder, spyder or ksi850?
