Saddle and seat post Questions

Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

Saddle and seat post Questions

2 questions, I picked up a Spec Alias saddle this weekend after going to my LBS and sitting on the ass o meter. I am replacing my Bontrager Race Lite Lux aka "ass hatchet" as its called here. Its does certainly put more pressure on my sit bones but after a few minutes I really don't notice it anymore. I know I have to spend many miles in it to get it to fit me. All that said I have to ask what may be a silly question. Where exactly should you be sitting on the saddle? Should your sit bones be right in the middle of wide part? More towards the front or almost at the rear of the saddle?

Also I noticed my cheap o seat post flexes side to side when I ride. When I have the seat mounted it looks strait then when I would get on the bike it flexed to the right a bit. So to make up for this I have it offset to the left a bit when I am not on it, but it will be perfectly strait with the top tube when I ride. If I upgrade my seat post will it remedy that issue? Or will all seat posts have some flex side to side?

OP - First question is relatively easy. Good bike seats give you a variety of places to sit. Move around - slide forward and backward while you ride, and you'll get a sense of what feels right, and when it feels right. Moving around on the seat changes the pressure points in your butt, but more importantly, it affects how and what muscles are stressed when you pedal. That's the point of changing positions - to find the sweet spot for climbing, for flat-road/high cadence, for downhill, etc.

The flex in your seatpost sounds odd. Cheap-o seatposts are typically heavier and have LESS flex than the light, high-dollar ones. What is is made of? What brand/model is it? Could it be that the seat mount where the saddle rails attach to the pose is flexing or loose??

Your body will naturally adjust to the most comfortable seat position after it breaks in. I have an Avatar and will vary my sit-bone positions 20+ miles into a ride from soreness.

As far as your seatpost... If its a CF post than there may be slight flex. If you have a cheaper post than upgrade to a Thomson.
