I’ve got a Reverb and my mate has a Thomson. Functionally both are equivalent, the only difference being that the Reverb is hydraulically actuated and the Thomson via a cable. Personally I prefer the cable for ease of maintenance, but iv’e had no issues with my reverb so far so its not really an issue. The Thomson is a lovely made piece of kit. it is proper quality, you can really see the attention to detail and where the cost is. The reverb is nice but obviously functional and just does the job. I can’t really choose between the two, both work well, seem reliable – 2yrs on my reverb absolutely trouble free, the top collar is just starting to develop a little play, but its a part that wears so to be expected. There is only 6 months on my mates Thomson so perhaps a little too early to judge, but all good so far. He didn’t pay full price for his Thomson, something like sub £250. Pricy, but a quality product. You can’t go wrong with either. What price would you pay for kit that just works with no problems at all? He’s got a KS jobby on his other bike (not a Lev) and he has had problems with it a few times, but it keeps going – but that wasn’t that cheap having said that.
I don’t mind paying for kit that works. I’ve bought cheap before and it almost always turns out to be a false economy.
