Looking for a seatpost for my winter road bike found these on ebay

http://www.ebay.co.uk/itm/31-6-350mm-3k ... 1233985562

31.6 and carbon for a shade over 20 notes delivered. What could go wrong? Anyone actually tried one of these?

You're riding along on a flat road, eager to test it. Then you take a speedbump, the post snaps, you lose balance and your feet slip off the pedals, your crown jewels get ripped apart by the sharp edges of the post's remains, you fall off, get run over by a passing truck, etc ...

apart from that, It'll all be fine.

:lol:

Bet they come out of the same factory as most x4 the price!

It states they have passed European tests? Request the standard they have passed and compared to others? :?

Producing CF parts is still a relatively specialist operation, I doubt they would be lacking decent QC. I would do one.

difficult to say but I have one of the Bontrager clones - the one below - and it has been fine, ridden it may be 3 times so does not prove reliability in any way. you would kinda hope if there as problem, the internet would have reported it - there was some fake Ritchey stems from china that snapped - pretty sure was posted on here in the retrobike foum.

I don't know but it's a great name for a band though.

But are the built to the same lay up schedule? It could be 95% cross strand mat under a thin layer of woven mat for all you know. Maybe they used cheap polyester resin rather than epoxy?

As for the European tests, do you really trust that claim? 5000 lumens from a couple of Cree XMLs and four $1 18650 cells :facepalm:

I had a cast alloy head brake off a UD carbon post a few years ago , there was a small alloy tube used to bond the 2 sections together , anyway i luckily landed crack first onto the tire (bleeding mess) and then hit the road (tailbone grief still to this day) It was a Teschner Europro frame that came supplied with the seatpost , I think they were made in Asia and sold as "Dolan" over there ? my point is the specifics of manufacture are more important than the brand name or place of origin (edited with a photo)

Surely someone on the internet must have bought one, so many listed on the 'bay?

Also took the certification comment with a pinch of salt.

One the one hand would normally leave untested chinese carbon, would certainly not use an unbranded stem. On the other hand no reason that it not be a perfectly usable item which may (or may not) come out the same factory as branded stuff. Only seatpost I've ever had issue with was a brand new Syncros, clamp bolt snapped first ride out and got the pointy end of a flite where the sun don't shine....

Personally I'd take a punt at that price.
Lets face it, plenty of us on here reguarly ride ancient aluminium and carbon frames and components that are probably well past their Use By date... 25 year old alloy handlebars anyone? :wink:
This is probably less likely to fail than many retro-components.
