Thanks for the response Cheers! or should I say cheers Cheers!??
I was looking at the 09 minute MRD absolute+ - primarily because of the weight advantage over the SID World Cups and the Durin SLs. There's very little difference weight and performance wise between the on SID WCs and SID teams from what I've been reading. Lots of discounted blue world cups around at the moment as well. I'm happy to sacrifice a few grams for reliability. Disappointed to hear about your experience of the EC90 CNT post. I was speccing that - though I've not read anything else bad about them (bar the price!). As it was nos I take it it wasn't the 09 model ?
The EC90 post I had was a 2003 31.6mm OD offset (aka setback). It was NOS and I picked it up off of ebay. I looked it up and apprently in 2003/2004/2005 Easton said it was ok for both mountain and road use. I had a 350mm length version. But in 2007 Easton changed it to road use only and only offered it in 27.2mm diameter. So... They probably figured that the offset version of the EC90 was not strong enough.
I'm very happy with my Thomson Masterpiece right now and I doubt I would ever choose another seatpost. I have tried all the lightweight variations out there... KCNC, USE Alien, Tune Starstruck, Token, etc... I find the Thomson the best out there. The USE Alien is not bad... but it requires a special head that you have to pay another 40 bucks for Carbon railed saddles. That peeved me big time on my other bike where I used a carbon rail saddle.
