Does anyone know of any good online guides for determining seating position?

The one gives some good information on seats in general. There is a 5 step thing on perfect seat adjustment. Later on there is info on there to change the type of seat if you choose to change your seat later.

I hope this works, since I can't post links since I have less than 15 posts.

Thanks, I'm going to read them.

I went for a 50 mile ride this weekend and have a very sore back to show for it. While I turned out my second best time, I feel that my seating position not only contributed to a very sore back, but kept me from posting my best time yet.

I plan to get fitted to the new bike setup this week, but just looking for a better understanding of how seating position can effect a ride and how to look for warning signs that my seat is "off'.

If your back is sore, it may not only be your seat by the placement of your handle bars. Sometimes when they are too close to the body, it gives more strain on your lower back. It is good you are going to get fixed for a new bike.

But WOW, a 50 mile ride, very impressive. Over here in Canada; Toronto that is equivalent to a little over 80km. Damn, you are indeed sir a MACHINE!!!!

Five Steps to Perfect Seat Adjustment

1. Level the seat and center the rails in the seatpost clamp.
2. Wearing cycling clothing, put the bike in a trainer or position yourself in a doorway so you can hold yourself up while pedaling. Have a friend sit behind you and watch as you pedal backwards. Raise the seat until when you pedal backwards with your heels on the pedals, your legs are completely extended at the bottom of the stroke. If you have to rock your hips to reach the pedals the seat is too high.
3. Mark the seatpost so you’ll be able to refind this starting seat height if the post slips or you take it out to ship the bike, etc.
4. Find the proper fore/aft seat position by placing the bike on a trainer (the bike must be level with the ground) and pedaling a while to warm up the muscles. Stop pedaling with one foot at 3 o’clock. Have your assistant level the crankarm and the pedal. Maintain that position while your helper holds a plumb line (a thread with a nut on the end works fine) against the indentation just beneath the bone that’s below your kneecap. Adjust the seat fore and aft on the rails until the plumb line bisects the pedal axle.
5. If the nose of the seat bothers you, tip the seat down 1 to 3 degrees. Don’t overdo it because a tipped seat will cause your body to shift forward putting added pressure on the knees and preventing the seat from supporting your weight adequately. If the nose bothers you enough that you want to tip is excessively, try different seat designs.

This is all correct, also try not to place the nose of the seat down as this will cause you to slide forward and put pressure on, well lets just say you don't want pressure there.

The seat must be perfectly level

Also you recently went arrow and that might be pulling you out too far. As a Wt lifter you have more upper body Wt than most and that might be putting stress on your back to be in that position. Try turning your stem upside down, this will bring your bars up and give your back a chance to adapt. then you can take it back down once you are used to the distance you want. This will give you more wind resistance but may make your ride less painful.

Went and looked at pic of your bike. Do not turn the stem upside down as this will bring your bars down. Great bike by the way. I just got my spinergys last wk. Did 80 miles yesterday the bike did great I did OK.
