I’ve had one for 6 months now.
It a really nice bit of kit. I can’t compare to a reverb (never had one – that hydraulic cable is a shite idea and you hear more stories of them breaking than any other post) , but it’s light years ahead of any of those cheap t-mars etc.. versions.
It’s been covered in mud/grit on almost every ride, but is just as smooth as the day I bought it.
The bar lever is great, although it does send the cable straight forward and creates quite a big loop of cable out front. I’ve seen photos of some people using a v-brake noodle to make it neater.
Only issue I have is it has developed a tiny bit of side to side play, but nothing that bothers me. One day I’ll get around to tightening the collar as mentioned above.
I also think dropper aren’t quite as comfy as a standard seatpost for big days in the saddle. They have a lot less flex built in when compared to a decent normal post.
Overall I’m glad I went with the Thomson instead of anything else, and would easily put it top of the pile when it comes to droppers.
