I have been cycling now for about 3 months after a health scare. I usually ride for about an hour every morning after which my bum aches so much I have started to stop halfway round to allow the circulation back. I have a good quality mountain bike and use a Selles SMP saddle, the one with the grove down the middle and the hole in the bottom ( not sure what the hole is for !! ). I have tried adjusting it to several different positions all with pretty much the same result. This is a middle of the range saddle and I have tried 2 other similarly priced ones. Before I splash out on an expensive saddle does anyone have any advise to why my **** aches so much and will paying more for one improve the ride or is this a pain I have to bear !!
