No, it does not work with those two. WT because their tube sticks through the clamp, and CB because their contact area is convex and not concave. If we see demand we would need to make specific versions for these.

@Sluni: It's all good. You are right, that happens all the time. Still, we are not the kind of people to be paralized by these facts, rather we believe in the transparency and document a lot of what we and our suppliers do social and eco wise, downloadable for everyone on our site. We know our main suppliers personally. We walk in there, have coffee with them. For example the main CNC supplier has a miniumum wage of 4950.- CHF a month (That's a non trained worker. The guys actually programming the machines will make around 7-8000.- CHF and rightly so!), 4 weeks paid vacation and all the insurance for all the workers. Plus 50% of their power comes from the solar roof. You can all find this published on our website, signed by us and the supplier. We agree, there is a lot of marketing BS. But we do our very best to proof in our case it isn't marketing BS. As for nature: No matter what, we believe in our laws and their reinforcement. At least in the countries we source. It's another history elsewhere. I can tell, because I am half Sicilian, and granted, there I would not trust the laws. If you would like to, we can email all our contacts at all the dropper manufacturers and we can email you their response. But I can tell you the answer now: No, no, no. And the reason that they cannot and don't want to allow third party supplier parts on their products is because they cannot and don't want to test these combos. Believe us, we have worked long enough at and with big companies in the industry, it just doesn't happen. That's the long answer. Have a great evening!

It is compatible with all KS posts, you need the DROP BEST UC M6 (since all KS posts use M6 bolts). Thx!

@GTscoob: Thx, pro insights :)

Thank you, really appreciate your support! No worries, the TT extender is in the works, right along with the dropper stem!!! :)

Honestly, when we made the first version for Reverbs only, we sometimes thought the same. But since then we learned that there are many needs of vastly different riders (from the occasional tri racer to even DH people using it to avoid tire buzz on the saddle and many more...) that it actually makes a point .)

@mtb-daniel: That actually corresponds to our gut feeling. But the reality seems to be different: There is a demand for adjusting rider position, and the reasons are very individual, we learned .)

Sweet bike! But in the case of daisy-chaining I would suggest you find a local welder to work on your dropper instead :)

This is just because we source ONLY from countries where workers and nature are actually protected. Down to the bolts and the packaging. So the price is very fair, for the consumer and the people in the supply chain And nature. And you wouldn't believe how much effort we, and our suppliers, put in to make that price happen. It would otherwise cost 3x as much. We work really hard to offer a fair product for a fair price. And it's true, you can buy a complete dropper for that, but we think we, and you probably too, would not want to work one day in one of the jobs of that supply chain.

You can actually find this info in the compatibility chart you can find here: https://www.fairbicycle.com/manuals Basically the only M5 posts out there are all Bike Yokes, Fox Transfer 2020 and older, Transfer SL and the Thomson droppers. For those you need to get a DROP BEST UC M5 or an M5 hardware kit to convert from a DROP BEST UC set for M6 or Fox F21. Everything else is M6. So for those you want a DROP BEST UC M6 or an M6 hardware kit to convert from a DROP BEST UC set for M5 or Fox F21. The exception: If you have a newer Fox Transfer (2021 or newer, the one with the weird head), you need a DROP BEST UC F21. But also for these: You can convert them by getting an M5, M6, F21 or even a road hardware kit. Sorry it's a bit complex, but that's because it is complex .)
