The non drive side/ left side has an egg shaped threaded piece which the bolt threads into, this eliminates the possibility of ruining the clamp, via the bolt, as this part could be replaced, but I haven’t seen it sold desperately.

Hope Tech 36.4 mm Bolt Seat post clamp

I bought these in august 2017, and used them since to now, 2019.

Cons:

  • The bolt has worn significantly, quite fast. I have two of these so I had to switch I did not want to round the bolt off, and end up with loose seat post.

  • the hex key does does not fit as tight as I wish it did, I have tried Park Tool Hex keys and Teng Tools bits which are even more precise than Park Tools Hex (Bondhus) keys. I noticed it was not good tolerances between the tool first when it the first use, with a park tool multi tool (Bondhus). I don’t know who makes the bolts.
  • Bolt can loosen up fast in big temp changes. Even with Loctite 243 the bolt has loosened up every time I took the bike out from the room temperature indoors to cold winter outside, few minutes and it was loose, so if you plan to ride with extreme temperature changes and ride hard it will eventually come loose and seat post will spin, this is also be common issue with seat rail clamps on many dropper post, or seat posts. Of course how fast it will depend on material combo and load, vibrations it gets, also had issue with loose bolts on Shimano brake levers clamps, and race face stems, but for secure stem Renthal Apex is has worked well for me, but for seat post clamps I don’t know which are the best, this was my first aftermarket seat post clamp.

I haven’t had any other issues with the clamp, the bolt turns smoothly

Pros:

  • the bolt turns smoothly
  • it fits precisely on the seat tube.
  • Lovely Laser etching
  • even surfaces, well made, no sharp edges, but it has a tiny texture to it, which also can bee seen, which some might like, you can clearly see it’s CNC machined.
