|Pelvis Tilted Forward??!!||VW|

|I read this "pelvis tilted forward" many times, but I don't know what it means. Can somebody post a sketch? Does it cause problem for male riders by added pressure to the male organ?
|Don't know about that but||lotterypick|

|I've found if I intentionally keep my back flat while on the hoods. My nether region feels better.
I was wondering if it was my shorts prior, but once I got aero and flat backed, things started to look up :)

|Sit on your bike & attempt to NOT have a flat back, in fact try to have the most curve you can. When you are moving from your normal position to the "curved" position notice that the more you curve your back the more your Pelvis "rolls back" relative to the flatness of the seat. If you get that, the opposite is also true. The flatter you try to get your back, the more you have to roll your pelvis, which has the effect of getting you "Up" on your sit bones. A good image is to try to move your abdomen towards the top tube. The only way you can do it (While seated on the bike) is by rotate your pelvis forward.
If you don't have a flat seat, or have way to much drop, or if your seat is too far back (or you are too stretched out) this motion will put more pressure on the "boys". It is no problem with a flat saddle & a well fit bike.

|Here's a picture taken from my last century. I'm guessing my pelvis was not rotated.
Although the picture doesn't show it, there was ~5% uphill grade at the time. I was sitting-up a bit on the climb, and therefore the locked arm.
By the way, the bike I was on was my new C40HP on its first century!
