I am researching a new saddle for my bike. I think that I need something with more of a WSD- I can't seem to get over the soreness with my current saddle. My question is, if I find a saddle I would like to try does my LBS have to install it onto my bike? I wasn't sure if it is something that can be done myself (with proper tools, of course.) This is my first bike, in case you were wondering. (Except of course for the 3-speed I had when I was 13! )

Thanks for your help!
