Thought that I would post some pictures in this thread. Keep in mind that I had these made a little stronger than normal since I am not a flyweight by any means and right at the weight limit for the parts.

NEW PARTS - No ti hardware yet. Pretty sure that the Ti hardward is about 12g-13g which would be nice.

OLD PARTS - Stock.

Great!

My retrofitted KCNC M5 hardware is 26.2 grams. I'm not so pleased using that with a Becker saddle, though. It's been okay so far, but I wouldn't want to crash it.

The claimed weight for the two carbon bits is 22-25 grams. The price is "140 z". Is that Euro?

added: It's 140 złoty, around 38 euro.

The competition, who was first to market, claims 19 grams.

Okay -- you guys convinced me. I'm in on this, too. I feel better about this with the Becker/Tune Concord than my kludged KCNC. Although I just got a KCNC post today from my favorite jewelry store, Bike Nüt to use with my SLR, to spare the Becker from daily use.

I just performed the same process as the OP (rebizap) on a 31.6mm elite post two days ago. However, I left a marginal amount of material in the center of the lower "craddle" to prevent junk from going down the seatpost into the BB area of my supersix I'm taking about .020" thick piece using a 3/8" Ball end mill and countouring it using a CNC machine with a program I wrote for it.
Before 194g
After 142g still using the steel bolts/washers/barrel nuts

Ordering up some Ti hardware today for it, hoping to get it down to about 135ish

Total time spent was about 1 hour, with most of that being drawing a surface and coding/inputing the program into the machine just for that center lower craddle. The rest was all done by hand on a conventional vertical milling machine and lathe.

As for length of the post, I cut about 1.25" off, so that the part number and all engraved text is still on the post. I know I could cut it down further, as there is about 5" of post in the seat-tube of the bike. If I cut that down further, switched to Ti bolts and trimmed the excess off the front bolt, I think I'd be at around 120g easily. For the cost of the Ti bolts, or about $20. That's light enough for me, and the strength of the post really hasn't been compromised in any way.

Tuning my 27.2 post today, I'll see what I come up with.

Oh you want tuning well I will give you Thomson tuning.

Stock upper and lower cradle 50g
Stock bolts 22g

Carbon upper and lower cradle 24g
Ti bolts 12g - will order these from Toronto Cycles in the next week.

Original weight of the Thomson modified post for ISP will be 130 and then I will lower that by another 36g so that finished weight will be around 94g or maybe lighter with the ti bolt coming.

Thomson seatpost head (currently at 130g, I have a ti bolt coming for the wedge, then you have the carbon craddle for it - interestingly my external caps are lighter, even though made of steel, coming in just over 100g generally)

Can someone post the grams lost to $ spent? Im interested in going a similar route with ti hardware and carbon cradles. Just wondering what was spent to grams lost.

Thanks
Justin

I cut my 26.8mm Elite down and it went from 230g to 180g. With Ti hardware which I now have that another 8g lost. I intend to try and modify the clamp to loose some more. If I can get it don to 165g I will be pleased.
