I made some carbon upper and lower clamps for the Thomson Post, they are the same shape as the original ones but half the weight and look tre's cool. I will put some more pics and info on my website soon.

In a dutch test the post failed, not even tuned

You need to provide more details with this sort of statement. Anything can fail if the test is sufficiently nonrepresentative of real-world loads. Any product which competes on weight is going to be compromising reliability to some extent. For example, a post optimized for a 56 kg rider is going to break with a 168 kg rider.
Similarly a post optimized for the road might not be best for mountain biking downhill.

Yes, the biggest reason for using a Thomson post is that the seat clamp properly spreads the load into the saddle rails, reducing likelihood of a bent or broken saddle. The clamp is also engineered that the post will bend before the clamp snaps to save your arse. Also it's pretty light - comparable to many carbon posts and IMHO much stronger and damage resistant than those. All that says to me that it's a foolhardy thing to meddle with the clamp unless you are prepared to do a similar amount of testing to ensure your parts are similarly strong.

I have two Thomson masterpieces on my tandem and they work flawlessly. Also the anodising does not flake off with a bit of British winter salt. The bolts are angled so that you can turn them with an allen key...These points are not true for some Italian products I could mention. Truly it is a superior device to many lightweight "tube with a hole plus two screws and a U" seat posts from Tune, KCNC, USE, WR Compositi, 3T etc....

Best close copy IMHO is the Syntace post and that's about the same weight but costs more. Case closed.

Here is a link to mine.

Im still using it as my every day seatpost.

Yes I will make some available, PM me if interested

Cool, PM coming your way.

fletch62: If you want, I have some carbon seatpost offcut that would probably suit a DIY job like that. PM me if you're interested, it's you'rs for the cost of postage.

Little OT: does anyone know if the masterpiece has Ti hardware? I know the Elite has steel, but not sure about the mp..

One that i have been looking at and trying to source is this:
The carbon cradle extends along the saddle rails and the top clamps are in line with the ends of the cradle so no extra pressure points.

Some data from my Thomson Masterpiece:

clamp diameter: 31.8 mm
original length: 350 mm (stated)
original mass: 190.3 grams
cut-section (3.9 cm): 9.7 grams = 2.5 grams / cm
final mass: 180.4 grams
sawdust: 0.2 grams (calculated)

clamps (2): 48.1 grams
cylinders (2): 9.4 grams
bolts and washers (2): 11.7 grams
cut post: 111.2 grams (cut)
uncut post (calculated): 121.1 grams

The clamp is an obvious source of weight savings. Not much in the bolts (8.3 grams here, saving 3.4 grams). Cutting is an obvious no-brainer.... cost me $5 at the local shop, around $0.5/gram.

me: So what do you think of these clamps?
girlfriend: You're asking hypothetically, right?
me: (pause) No. They save 30 grams!
girlfriend: You can't be serious. I would be very upset if you got those. They're totally untested.
me: Yeah... well.... if they failed, they probably wouldn't do so catastophically....

Anyway, it looks like I'm out .
