precise saddle levelling with a two-bolt clamp?

Hi, I'm riding a Dean TI seatpost on my road bike, which has a two-bolt clamp.

I am having a hard time getting really precise nose-up/nose-down adjustments, can anyone shed light on the proper method with a two-bolt system?

I put a level on my saddle and then start tightening one bolt until its just snug (not tight). Then, move to the next and bring it up to similar torque. Repeat, alternating between the two until they are each tight. Just keep an eye on the level and manually adjust the saddle as required. This technique has worked for me on way too many posts (Campagnolo, Moots, Thompson, Easton, etc.).

I have a Thomson Elite seatpost. What works is to use a level. I put a flat one to two inches thick book on the saddle, the level on top of the book, I then proceed to dial in a flat saddle-top by adjusting the bolts. Tightening one bolt, while loosening the other is the way the Thomson works. And it is pretty easy.

The level readings determine for me which bolt needed tightening/loosening.

My tip? Get a level (I paid one dollar for mine at the Dollar Store). It helps tremendously with the needed adjustments.

Regards,

If you have determined that a level saddle is best for you, use a level. Otherwise, adjust it to where it works best for you.

What I actually meant was not a perfectly level saddle, just precise adjustments of the up/down. I'm using the 'tighten one bolt, loosen the other bolt' technique, but it doesn't seem very precise - I often end up with the saddle a little bit off from where I wanted it when all is said and done.

I probably just need to keep trying

Thanks.

Turn each bolt a little less. Check if the saddle is in the right place. Repeat if necessary.

If you need to move the saddle back, loosen the back one first, then keep pressure on the nose while you tighten the front bolt. When it's about right, you can let go. Snug up the back one, then alternate front to back a quarter turn or whatever until it's tight.

If you tighten first, there's nowhere to go.

It works better if you loosen one bolt then tighten the other.
Use 1/4 to 1/8 turn to get fine adjustment, just like tightening spokes.

I use a small 5" Craftsman plastic level I got a Sears. Fits the variuos spots in a Brooks B17 very well.
