SAFETY WARNING! Broken EC70 Seatpost(3 posts)

SAFETY WARNING! Broken EC70 Seatpostpitt83

I was riding home today. Stopped to peel a layer as it was warmer than I thought and I'm used to at least 2 layers lately.

I stood to accelerate, sat down and BOOM! Like a rifle shot, the Aluminum head snapped from my EC70 seatpost. Post itself was whole; the head completely and cleanly detached. Scared the hell out of me. No injuries since I wasn't fully weighted. I had to ride about 1 mile standing to catch a ride from my wife and meet her.

The post was only 1 1/2 months old and appeared to have not enough epoxy to hold it together. I noticed some of the "coating" flaking after the first week and thought it no big deal? Maybe that's the first sign?

I was fully refunded with an apology and upgraded (not free though) to a Deda blackstick with an integrated monocoque head. Hopefully, that will be OK.

Not to sound like a ringing advertisement for Thomson, but I think they are the best seatposts, simply by process of elimination.

The weight savings of a carbon post are minimal. IF there is a failure, it usually is at the head where the bond is. Don't know if a monocoque design is any more reliable, but it sure is pricier.

Most other aluminum posts still have the bonded head and an inferior clamp. The Thomson is a solid piece of alum with a robust 2 bolt clamp. I haven't seen a better or sturdier design yet.

So save a buck or 2 and get the Thomson. Sure it doesn't look as cool as carbon, but you won't have to worry about impaling yourself. And the finish, like the rest of the post, is really durable.

That really suprises me. I suppose with any component on the market, there is some risk of actual manufacturing defects. I know there are alot of the EC70 posts around here on the road, as I see people with them all over the place. I've been on my EC90 (have yet to see another one of those around) since February, expecting it to be a long-term item. That's cool that they did exchange it for you. the only reason I got the easton was their 5-year warranty, which goes way above the USE-Alien reccomendation of replacing it annually.
