Bicycle Mechanics - Seat Position
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
I can't get forward enough on my seat to ride comfortably (it's at the end of its rails).
I think i need another inch or so.
My idea is to rotate my seatpost so that the set back clamp is facing the other way.
Do you guys see any problems with this besides it being funny looking?
You might not be able to get the seat tilted to the right angle. Seatposts are usually designed to go a certain distance on either side of a level seat, and when you put the seatpost in backwards, you're going to be off by about 40 degrees. Unless you're lucky, you'll probably hit the extreme of the adjustment before you get that 40 degrees corrected out to level.

Hate to tell ya this, but your bike is too large. One not perfect compromise would be to get a shorter stem to lessen your reach. You might also try a straight seatpost if your existing one has some setback to it.

Ditto MacG. There are seatposts available with infinite adj angle. Bontrager's Race X lite is one. Perhaps a stem riser or shorter stem?
It's possible you've moved your seat the wrong way. One problem with moving your seat forward is that it moves your centre of gravity in front of your feet, causing you to tip forward off your seat onto your hands, putting too much weight on them. It's like a guy bowing forward at the waist without letting his butt move backwards to counterbalance - he'll fall on his face.
Try raising the handlebars, and moving your seat back to where it should be. The classic advice on seat position is that the front of your knee should be directly above the centre of the pedal when your foot is in the farthest forward position, but Sheldon Brown (http://www.sheldonbrown.com/frame-sizing.html)says recreational riders can move their seat a bit farther back, and should move their handlebars up and/or back to go along with it. As others have said, you may need a shorter stem, but try just raising the handlebars first, if you can.

I had trouble getting my saddle forward so switched to a seatpost with an inline clamp.
Before you switch, check that the cranks are not too long for your legs.
It may be that your upper leg is proportionately quite short compared to your lower leg so the correct position of your saddle is further forward than for "normally" proportioned riders. This is why I use an inline post.
In the old days, people made custom frames with steeply angles seat-tubes for wonky riders but now we have a vast selection of seatpost laybacks to accomodate any rider on a std geometry frame.
