The saddle my bike came with
and hurt so much that I stopped using my brand new bike (much to DH's disgust cos he bought it for me as a birthday pressie). I read an article that these new narrow saddles are very bad for women (and, in fact, not great for men) and they recommended the use of 'big bum' gel sprung saddles. There weren't any available in Doncaster that I could find so I got one off eBay - a bit dear at 15 squids plus P&P - but INHO worth every single penny.
