Subject says it all! I've been out of Mtn biking for a while, and what I currently have (Thompson Elite Setback) needs to be replaced with a zero, or smaller setback post. I also want something black to match my frame (Sworks aluminum). I've looked at a few different options - crank brothers cobalt 3, easton EC90, raceface Next, and none seem to be that great. I could always order another Thomson in black, with 0 setback, but the thing just looks so boring. Any other good options out there? I'm 195 lbs, so super light weight need not apply. I also will probably use a quick release, so I'm mildly concerned about torquing a carbon post properly - not even sure if this is an issue these days or not.

Thanks!

Whats wrong with the ec90? I had a 30.9 zero offset at one time and iirc it was like 180g with ti hardware. Pretty light and adds some comfort to the ride

The Thompson is the lightest strongest post you can buy. Black is boring full stop.

Thomson Masterpiece or if you want carbon - Easton EC90.

Well, I really liked the EC90 too, then I looked at reviews here and there; on MTBR specifically. There were a few that said the clamp was poor, and that the post slipped under "proper torque" rates. You guys obviously don't have those issues? What about using a QR with a carbon post. Anything to really worry about? I mean you dial in that QR tension once, and hopefully every time you loosen/tighten, its the same torque.

I'm a big fan of carbon seat posts. The little bit of flex they offer feels great on a hardtail.

Easton EC90...with KCNC seatpost yokes instead of the original heavy plate you can save a lot of weight, even 70 gr 8)

I've been using a KCNC Scandium Ti pro lite Seatpost for about a year now (around 5000km offload) and it has performed well. 148g for my 30.9mm version uncut.

Thompson Elite on my FS trail bike - as it gets hammered, EC90s on my FS Race bike, & 29er HT.

All my bikes are carbon - I've never had any issue with any carbon seatposts or anything else.

The Thompson is a nightmare to change saddles on, the EC90 is 2 mins.

I've never tried the Thompson Masterpiece. Is it better/lighter than the Elite ?
