Use Alien - lightest seatpost I ever threw away...(6 posts)

Use Alien - lightest seatpost I ever threw away...TFerguson

Bought the Al post for my MTB. After the second time it came off the back after landing a small jump, I moved it to my road bike where it would get no abuse. On yesterday's road ride I moved back on the saddle for some power up a hill and back it went. It didn't come off, but the nose was pointing up at about 30 degrees. The Alien head is a nice, very light concept that doesn't work and I seem to be a slow learner!

A friend of mine had the same trouble and what we found was that if you retightened the bolts after the first couple of rides, it would stay put. It seems the wedging action that clamps it in place has to "seat" for a few rides and then all will stay where you want it. I've got to agree that for the money you should not have to mess with it. And whats up with the bolts, couldn't they provide just a few more threads?

Good luck, Bob

Until the heads are just poking through the front of the clamp; USE'S instructions do recommend checking the tightness after a little time in the saddle. I've had several versions and never had any problems, never even had to retighten, but I could never get enough set-back. I also put some Phil's grease on the disassembled head and clamp mechanism; seemed to help.

FWIW, I've never had a problem with single-bolts like Campy and the new Easton. Oh, well. Solving a problem that didn't exist?

I tightened it to one screw thread past flush (the manual said something about this). you do have to tighten it until some screw is poking through. yes, it is a pain, and a severe one at that.

I had my Alien carbon loosen on the first long ride. After I tightened it, no problems. The secret to getting it right is to alternately tighten each screw, as tightening one relatively loosens the other, until both are tight. Carry the appropriate hex tool with you the first few rides.
