Sorry for borrowing this picture from Rik. Since the last thread regarding kg281 is "buried" too deep in the discussion list, and I couldn't figure out how to send email to the original poster. I would like to pose the picture without permission and ask the following question:

What kind of a seatpost do you have on the kg281?

I'm looking for a seatpost for my new kg281. I understand that there are 3 choices--American Classic, Look Ergopost 3 and Look Ergopost. In fact I have a Look Ergopost 3. With the "setback" setting, the saddle is too far back even when the setting is in the most forwarded postion. I'm thinking of returning it and get another sestpost. Just looking for another option.

Try looking at USE posts. Not the carbon ones, the look seat binder puts too much stress on a corbon post and makes them fail. But USE has their aluminum post at 175 grams. for a 330 post. Plus they come in 25.0mm diameter

Go onto ebay and look for older Campy or Dura Ace seatposts in 25.0. They are both aeroposts and don't have as much setback as the LOOK posts. I have an older Campy 25.0 I'll sell you cheap. The only problem with the post is it's a shorty. It's only about 200mm long total. Email me at if you're interested.

You can also use a ITM Millenium seatpost. It comes in 25.0.
have a 386 with the ergo postPaul

I was able to make the right set up for what I wanted. i have the ergo post on a 57 cm 386 frame, and just made the height adjustment. Had plenty of adjustment for fore/aft position using the first position (closest to the bar). Have to remember that this post was designed for all types of riding. Don't understand what one person said about them failing due to the seat post clamp. I took a piece of the carbon steerer, and compressed it in a vice till the sides just about touched, and after releasing the vice, I was able to put a one inch spacer over the piece of carbon. It returned to it's original shape. It seems you would put much more pressure on the carbon steerer. Have to be careful when tightening any piece of carbon. Look givres the torque specs.

Thanks for all the input. I'm looking around for online stores that carry 25.0 U.S.E and ITM Millenium.

Paul, do you have the "Ergopost" or the "Ergopost 3". The Ergopost 3 that I have has a "much" setback setting than the Ergopost. Even I set it to the most forward position, the seat clam still sits about 1 inch "after" the front of the post, if you can understand what I'm saying. You can check out the 2 different seatposts in Look's web site. Thanks for you input also.
have the ErgopostPaul

I've been to that web page, and saw hte deign of the ergo post 3, and didn't like it. It seems that you can't move it as far forward as the ergo post. The ergo post 3 look like it belongs on a small frame. Don't understand that design. I recommend getting the ergo post. Where did you buy your frame? has ergo post for $112.00.

The ergo post looks real nice on the Look bikes. Have a picture of the 281 set up for Big Mat using the ergo post, and the position of the clamp is all the way back. A picture of the 386 set up for a time trail has the clamp all the way forward on the ergo post. I believe this design is used for small frames, and all types of racing. If you notice, when doing time trails the rider sits forward on the nose.

If you can, swap for the Ergo post, I'm sure it will work. Plus, you will have more height adjustment.

good luck

Good guess! I did buy it from last Oct. I asked them to replace the Deda Newton Bar/Stem with ITM Millenium Bar/Stem after hearing so many horrible stories from this board. Back then I ordered ergo 3 without noticing the setback, and also they didn't have ergo anyway, at least not on their site. I'm settling with American Classic for now because of its low pricing. I may consider getting an Ergo if I getting something from Totalcycling in the future. Shipping is quite expensive. Another choice will be an USE alluminum post. It's light and cheaper then Ergo.

I bought mine on ebayDave Hickey

Keep checking ebay. I bought a barely used Ergo Post for $85.00. Biz4bikes is selling new ones on ebay now for $115.
I would't hestitate to buy used with this seat post. The ergo is VERY solid.

Nice bike! The seatpost is an ITM Millenium aluminum post. Though it's a bit difficult to adjust, it has worked well for me once set up.

U.S.E. alien carbon post (25mm) on my KG281. The post is very lightweight AND a bitch to get adjusted.

I bought it from labicicleta(sp) in Buffalo NY for around $90. I wouldn't get this post unless you are reasonably patient and a semi-decent "wrench".

good luck

I've considered U.S.E carbon, but it's a bit expensive. Excelsports carries it with both 27.2 and 25.0, and it clearly says that it SHOULD NOT be used with LOOK frameset. I wonder why......
i use american classicWagnerite
Jan 15, 2002 8:29 PM
I use american classic, which is made in Taiwan (geddit?)
It was only 35 bucks from so i got it. Had a heck of a time locating a seatpost that was 25mm diameter. unfortunately, all by the AC was over 80 bucks... so guess which one i got. maybe i'll spring for the expensive ones when Cipo asks me to be his new lead out man, but for the occasional century and training rides, can't beat the AC seatpost
Design of the seat tube??Paul
Jan 16, 2002 3:59 AM
Just a guess, will look more closely at my ergo post, and will measure the roundness. Why don't you ask Excel sports? Colorado Cyclist carries the same post for 130.00, but there is no warning about using it on a Look.

Have to be careful with this stuff, that's why on the Colnago C-40 they give you the seat post, believe it's 28 mm.

It's the design of the worm screw LOOK usesDave Hickey
Jan 16, 2002 7:02 AM
The seat posts on LOOK's use a worm screw to tighten the post. My only guess is the walls are too thin on the USE. I use and Ergopost and old DuraAce and Campies in mine.

Could be right........ the dang thing is purty scary light.

My Alien post occasionaly slips from side-side if I put a lot of sideways pressure on it. The pinch-bolt has deformed the thin wall carbon tube. I've been thinking about machining a thin Al sleeve to help support the inside wall where the pinch bolt is located.

re: setpost for Look kg281Dave Hickey
Jan 16, 2002 1:55 PM
how about a wooden dowel/plug inside the post where the bolt deforms the walls?
re: setpost for Look kg281CT1
Jan 16, 2002 9:55 PM
I suspect the wood dowel would work also. I'll still try to get my buds to machine me an Al sleeve though.
