Mountain Biking - Seatpost with NO layback?

How do you measure the seatpost?

I have a ritchtey seatpost, a cheap one with no name like Comp or whatever on it. I saw the Comp one online and it said it was 250mm which is 10 inches. I measured mine to the min insertion and it was 10 inches, so mine is a 250 right? Becuase I need a longer one.

Also I need one that goes straight up, Im already too far back on the bike and have the seat set all the way back on the rails to move me forward. Im thinking that maybe I can get a seatpost that dosent have any layback to push me forward a tiny bit more.

30.8 is the size.

Thanks!

Have a look at the Thomson line. They come in a wide range of sizes and the standard model has not setback.

You will not only get a seatpost with zero setback, but you will be getting the best seatpost the industry offers. Go Thomson - you will not regret it.

Excuse my ignorance, but apart from height, setback, weight and cost, how much do seatposts differ bac?

Hypothetically - Im sure if he bought a 280mm Thompson Carbon Fiber Seatpost, it would be the same as buying a potentially cheaper brand? I just dont get it.

And besides, its a seatpost, weight wont differ to much. If youre a weight weenie.

Thomson seatposts are aluminum and very strong. The adjustment is also very simple and will not slip.

It's not about weight - it's really about performance. There are plenty of lighter posts than the Thomson line. However, the adjustment and quality of the Thomson is what makes it worth the money. They won't slip at the rails or at the seattube interface like cheaper posts do. They also have a built-in seat angle device that allows you to reinstall the post at the exact seat angle if you have to remove your saddle.

I own 6 bikes - they all have Thomson seatposts. That's how much I like them. :)

Hey if anyone spots a deal on them it would be appreciated, also if you can tell me if the length is the up to the min insertion line or the whole seatpost, thanks.

I have thompsons, eastons, tru-vativ, no name branded from the bike manufacturer.. all work the same. My favorite is actualy the sdg ibeams.

I prefer Easton. I believe they are a better value tha Tompson for us non super duper crazy riders.
Tompson is THE best but I dont need the best , I just need very good and very durable
