Forward-leaning seatposts?

My geared bike has an overly long top tube, but is otherwise fine for what I use it for (rain bike). Is there such a thing as a seatpost that moves you forward? I'd get a shorter stem, but I'm already at something like 80mm, and there aint much further I can go.

Check with the triathalon guys. I think that they sometimes use stuff like that.

Profile Design makes an off-set seatpost called the "Fast Forward" (http://www.profile-design.com/2006_p...t_forward.html ) that does what you want.

However, moving the saddle forward to reduce reach to the bars can upset the relationship between the saddle and the crank so be sure you aren't creating one problem while solving another.

If you can find one, a Control Tech seatpost can be run in both directions.

It will throw your fit all off. When seated properly with the pedals in the 3 o'clock and 9 o'clock position, a plumb-line hung from your front knee will hang directly over your pedal spindle. Sprinters want to be a little forward of that (<1 cm). Climbers want to be a little back of that (<1cm).

I would imagine that a forward seat post would put you a couple of inches too far forward. Not a good thing.

You could always "flip it" (the stem) so that you have rise instead of fall and/or you can change the angle of your handlebar if you have a dropbar.

thanks all. I may get that "fast forward" thing. again, this is a utility rain bike, so I'm more concerned with comfort on a gross day than I am with maximum efficiency. the stem is already flipped up.
