Although it looks kind of dramatic with the bent shape, it actually has about the least amount of setback of any setback seatpost you'll find, just 16mm. Most setback seatposts have 20-25mm of setback, and of course most of them get their setback from their shape at the top, not well down the post like the Thomson.
I have a Thomson set-back on one road bike and the bend starts about 2 cm above the seatpost clamp so there isn't a lot of downward adjustment available. I also need a set back post and the Thomson is adequate. Also, at the time I bought it there weren't many 31.6 mm posts available and I didn't want carbon. It's been very good and I'd get another in a minute.
