I took my bike to the LBS which is on my way home from work, not very close to our house but they sell the saddle I was looking for. I stopped in there on my way home 2 weeks ago to buy the saddle, and Stan, the owner, suggested I come by this weekend with my bike so he can see my fit on it, suspecting the problem may not be my saddle (which agrees with the thought of many of you who responded to my earlier post about needing a new saddle).
So we went today. First thing he noticed is that my 21" bike (the Giant Cypress) is a little too big for me. Not too tall, but too far of a reach even with the stem as forward as it can go. But he worked with what I have. First he moved the saddle forward a little, and lowered it a tiny bit. That helped, but I was still sliding forward on that big fat satin pillow. So he put on a Specialized BG2 Sport Saddle and WOW!! WHAT A DIFFERENCE!! For the first time on this bike, I could feel my sit bones on the saddle, and I didn't slide forward one bit while riding it.
And.... it's cheaper than the saddle I went in there for. Stan did not just hurriedly sell me the saddle I wanted. Instead, he suggested another one that is less expensive, but very popular, and spent about an hour making adjustments and making sure I was happy, at no cost to us (we did pay for the saddle).
I highly recommend Stan's Monrovia Bikes (in SoCal). Can't wait to take off on my next ride to test-drive my new saddle this weekend.
