put the Deda seat post with a 25mm offset on my bike, with a Selle Italia SKL saddle. The saddle has stop marks on the rails to show you how far you can move the saddle. I only have 5mm for forward or backward adjustment. It doesn't seem like very much. I think it really restricts you from making much of an adjustment. I was thinking maybe the clamping part of the seat post is larger than others and I can cheat some, but I don't know if I should try it or not. I would hate to break a rail 50 miles from the house. What would you guys do?

I am a shortie and have my saddle as far forward on my seat post as is possible.



You can see how far forward this is and do sit on the nose of the saddle putting more stress on the rails than normal. May help that I am a lightweight but have yet to damage a rail on any of my saddles---Except for a cheap one that was on the offroad tandem and a hard landing bent the rails.

maybe cheat a mm either way?

Hi George... been wondering about you lately. How much adjustment do you need? If just a little you might fudge over the marks a bit. If its a lot, then a non-offset post would be needed. And also the rail material would affect what I would do... a softer material would bend before it would just break so the risk of cheating would be less. Can you maybe post a pic of the situation?

George

Thanks guys, for the replies. I had to run after I posted the thread, but I called a Large dealer out in Washington and he said I shouldn't have a problem, if I slide it back the 5 mm, I think I need.

I'll bet that he sells saddles but that's what I'd do.

Realisticly, it looks to me like you have 2 choices - buy a new seatpost or try it and risk your saddle rails breaking. Of course if the saddle rail breaks you'll have to buy a new saddle AND a different seatpost. How lucky are you usually?

George

Yes, I did buy a new seat post and I thought it would get me back far enough and I really don't want to buy another one. Neither does my wife I feel I'm real close to being balanced on the bike and a little back will do it. No I'm not very lucky, that's why I don't gamble

If you're a lightweight, you're stressing the rails a lot less than their ultimate design load, so exceeding the position limit marks would less likely cause a problem.

190# so I guess I'm kind of light.
By the way I'm on my 3rd week without the Glucosamine Chondroitin and have my fingers crossed.

stapfam, looking at how forward you have your saddle, why do you have a setback seat post? Not trying to be rude, just curious. Also how much drop do you have. I've been playing with that as well. I actually felt better with a 3" drop, but my back couldn't handle it. I know I have to do it a little at a time and I tried it all at once, just to see how it felt.

This is the seatpost that came with the bike and is the same as the one on the TCR. I know I should look at an inline post but this one does the job- is light and hasn't cost me anything. On the bar drop- Both the TCR and Boreas have 4" and it is comfortable. I did at one time flip the stem but that took it just a bit too far. But the drop is also dependant of reach. Shorter top tube bikes and I find I need to raise the bars. I have tried longer reach bikes but they do not fit me. I have a 535mm top tube on both bikes and they each have a 100mm stem. The TCR did start off with 2" of drop to the bars and I felt was right but one day decided to flip the stem and take a spacer out. Bars were as near as damn it 4" lower than the saddle and it changed the Bike. Don't think it was faster but it did put me in the right stance for better acceleration.

But have to be honest and state that if the shop had not set up Boreas with the bars that low- I would not have tried it. They knew me better than I did and told me to try it. I did and it worked from the first pedal stroke. I do have a back problem and I am one of those that has found a long low reach to the bars works for me. And come to think of it--I used to run the mountain bikes with the saddle above the bars till The bypass and I had to modify the ride position to take the strain off the chest--But that was 12 years ago now.
