USE Alien seatpost blues, or new 25 mm seatpost(8 posts)

USE Alien seatpost blues, or new 25 mm seatpostorange_julius

Hi, I have a 25 mm USE Alien seatpost on my Look KG 361,
and I have almost made up my mind on giving up on the clamp.
At the end of a ride with any significant climb, my instinct
to scoot back on the saddle when pedaling hard would tilt
the saddle up such that the rear clamp block has only
another millimeter left before it will have fallen off the
top of the seatpost. Needless to say it seems to have
strong potential for a really nasty accident. :-(

I think I have followed the online instructions closely,
without much luck. Can somebody share his/her tips?

So assuming that the USE situation is beyond repair, I'd
like to get a new seatpost. The problem is that the KG 361
uses 25 mm seatposts. It looks that 25 mm seatposts are
not very popular. Can somebody share his/her recommendation

Thanks in advance!

The LOOK ergo post is bullet proof. Yes, it's expensive but I've had 0 problem. I have 4 LOOK bikes and I use either a the Ergo post or the older Dura Ace or Campy post. is selling a Campy victory post that is very nice.
ITM makes a 25mm, but I haven't used one (nm)nazgul

It seems odd that the saddle would shift under pressure. The last time I changed my saddle, the mechanic didn';t screw the bolts completely through the seat clamp and it shifted on me later that day. When I checked it at home, I noticed that the ends of the bolts were not visible from the front part of the clamp. I reset the position and slowly screwed it back in until the ends of the bolts came out the other end. It hasn't moved since. If that's not the problem, maybe the screws are stripped or something.
Good luck!

I put an American Classic post on my look.
They make a 25mm seatpost, and it is fairly lightweight.
Very simple and fairly reliable clamp design (had to tighten it probably once every two months, just keep an eye on it, and use locktite.
I just bought a USE, and wish I hadn't.

It's no more complicated than a post needs to be. Well made, and choice of colors, silver, black and a Ti model if you want to fork over the bucks
Yup, Am classic, no problems on my 361. nm.mainframe

In frustration I tried something that might sound odd
given my problem with the Alien: I dabbed lubes on
the entire clamp unit. Tightened everything up, and
went on a 2.5 hour ride this morning. And IT STAYED!!
Despite some amount of climbing and exerting some pressure
on the saddle.

I can't really think of a good explanation but I thought
I'd share my findings. I'll report back in a few weeks
if the problem comes back.

In the meantime, I've ordered an old Campy 25 mm post from, in case this doesn't work. The AMclassic
post does look nice though, but the Campy one is half
as much and I like Campy stuff ;-).

Thanks for all the comments and tips!
