this will be my third saddle, trying to get away from that certain numbness down there. the first was a stock saddle on the giant ocr2, no groove, and after a 25 mile ride, i was numb for almost 3 weeks. egads. then went to a mtb with a pretty good groove, numbness only for a couple of days. well, i do not like any numbness. so i understand the selle italia slk will do the job. any remarks on this?
