3 position would be fine for me, but frankly the post is nearly always slammed or in climb setting (all the way up or all the way down). I have meniscus issues that mean seated pedaling is terrible if the post isn't at proper full extension.

I occasionally use an in-between setting for either rolling XC sections where I'm going to pop a few rollers or super technical climbs where a wheelspin, missed dab, or tip over would result in falling off a cliff.
But even for those situations, I prefer the positive and stable in-between height of the E.13 rather than wasting seconds fiddling around getting it "just right" with an infinite position post like the OneUp.

Next time I need to buy a post, a mechanical like the E.13 will be at the top of my list.
i'm a fan of it too. unfortunately e13 discontinued the trs dropper.

Oops, I'm out of the loop. Was there ever a 200mm version?

Understandable really. E13 seems to have a bad rep in general these days, and a mechanical dropper is decidedly non-sexy.

How many MTBR freds do we suppose would pay $200 to PUSH their Reverbs?

Nah, 170mm was the longest version. It's a bummer really, it was a super reliable post, and works equally flawlessly in cold weather too. Nice remote too.

None, they're probably broke from buying the axs version

Infinite adjustable height, all the time. I had a 3 position and hated that.

I have an E13 on one of my bikes, out of the box I had to get a stronger spring from E13 to help it return to fully extended and it still doesn't always do that. So I have to pull it up via the saddle while standing on the pedals.

I had the version after that didn't have that issue... but yeah, that was part of what doomed the product.

Hmmm...seems I traded my vertical play for horizontal movement. The bontrajay is rigid vertically but does have some nose movement. we'll give it a shot on trail and see if it sucks.

BY Revive for me as well - Just over 18 months in at this point and very happy. Smoooth.
Got mine out of Germany for a decent savings.

My bikeyoke's are "in the middle" as far as lateral wobble, it's not bad, they've been in use far longer than any other droppers I have and are on my primary bikes. That means they've each seen seasons of use, IDK, like 4 or so? My transfer is the best in this regard, but I've used it the least, I used it for a few weeks, it crapped out, I got the first bikeyoke, got the transfer rebuilt, only used it over the summer on a fatbike that I don't ride much/hard during the summer. Now it's in it's winter use...where it doesn't come up fully when it's -F evidently, but whatever, it's lateral play is the least. The PNW I bought this year is by far the worst, after just two months, it was worse than the bikeyoke's I'd been abusing for years.

AFAIK, the bikeyoke uses slightly "curved" brass pin bushings. The slight curve/warp helps to eliminate play, but obviously wears out.

I've been using BikeYokes since June 2017. I would still be on the same original post except last year I got a great deal on a 185 version, so I sold my 160. They have a tiny bit of lateral wobble on the stand, but I've never noticed it riding. I do the basic maintenance (with the kit that includes a new foam ring and brass pins) once a year whether it needs it or not. I've had to use the reset lever maybe 3 times, usually after I bump the dropper lever while the bike is vertical (wheeling it into my garage, for example). They just plain work, and are smoother than OneUps. I see no reason to use anything else unless you're heavily budget limited.

Another advantage of the BY is a simple conversion between various seat tube diameters without having to use a seat post shim. I think I paid ~$30 for mine when switching from a Canfield frame to a SC.

Yup, forgot to mention that. I had a 31.6 and converted to 30.9 for my GG.

That’s just actually broken. Are you sure it’s not over-clamped? I’ve heard of that on a few dropper models...

You don’t need to service the cartridge; it’s a sealed unit. When it eventually dies you just replace it for ~$30. Probably less in the US I would guess.
Ah, so not serviceable. Examples of the cartridge for sale? I'm skeptical.

OneUp also offers replacement dampers for $60US.

I haven't needed to change mine yet.

It's not specific to SDG, it's a standard gas cartridge, made by a company called Wintek. They supply Giant, Bontrager, SDG, that I know of, probably others...

SDG Tellis with the replaceable cartridge. Super easy to service too:

View attachment 152181
Interesting. My bonty is virtually identical internally to the tellis...I did not know that. Took it apart last night and fiddled with the keys, including flipping them both. That seemed to improve the wobble, and a little extra grease smoothed out a little stickiness at the top. I think I can add a little spacer behind the keys to get it even firmer, but it might be good enough not to rattle now. This post is a huge improvement over the complete lack of user servicability of the thomson.

The SDG keys, despite being plastic, have an obvious 'way' they go in, they are rounded at one end and pop perfectly into machined slots of the same shape in the shaft. Seems to work pretty well.

My PNW has some wiggle, but I dont let it bother me. Only time I notice is when I'm off the bike, otherwise, it has no apparent impact whilst riding, or in operation.

Is this not the case? Is amount of play indicative of some other performance measure? Or is it just a preference thing?

All the posts I've had or used have all had play.

Maybe solid at first, but everyone had play after use. Which I guess is expected given how most are designed.

This is play as in wigging or twisting. Not the entire upper portion pivoting around the bushing or something. If that happens, I'm sure its not good.

No twist/rotational play in my KS Lev at the shaft at all....but there is a tiny amount of twist at the head/clamp if I really wrench on it. Have tried many times to make it go away and can't. Honestly pisses me off more that the play is there and not at the shaft/body interface.

Mine is/was loose enough that it was rattling on the trail. Like, I could hear it when going through rock gardens. Lots of people ride bikes that sound like garbage cans filled with nails and bees, but I've made a lot of effort to make mine quiet, which makes noise like this extra obnoxious. My thomson was mostly preference- a few mm of vertical play is not a deal breaker on the bike, but it was extremely obnoxious in the stand. I reversed the keys in my bontellisger and the play is dramatically lessened. If it's quiet on the trail, I'll be happy.

Fair enough. After a season on it, my PNW isn't noticeably noisy while riding, but I can see how it might get annoying if it was.

My PNW wiggle is easily the worst and sloppiest out of my posts, especially alarming considering it’s seen less use.

There any sort of remedy for that? Or is it just the way that it is?

I've never taken a dropper apart, so I'm not familiar with the insides.

Could somebody rich try the Vecnum?

I have the AXS, don't really like it.
I have the Moveloc 2 and am happy with it. Besides it being super sensitive to clamping forces (I needed to buy their specific seatpost clamp, otherwise it would bind, could be the frame as well) and sometimes the lockring at the seal loosening a little it is super reliable. A re-grease once in a while and you are good. I like the fast action/movement and predefined heights.

Yeah I really like the simple design, I stripped down a Thomson Elite today and did not enjoy pulling it apart, assembly will be less enjoyable. My Vryron was simple in comparison but needs a fancy bleeding tool when the seals poop out, our importer is an E-bike specialist, and needless to say, they can't do anything.
Vecnum next time.

Customer service was top notch for me as well. When I had the issue with binding after the initial install, they were super quick in helping over e-mail. Even gave me a special price for their seat post clamp (I hadn't ordered it initially because I thought I had a good one)! :thumb:
I am toying with the idea of buying a Vyron so I can move it between the bikes that I less often ride, but I am a bit scared with the reports of slow reaction times and it staying open for a moment before locking. I use the dropper a lot as we have quite a few of these short 10-15 sec downs, followed by an uphill.

Even a slight delay of a second would be way too much. Think about coming up on a steep rock or a tree to duck under, you don't want to be lowering the seat before you need it and many times that decision is on the fly, not planned. I just can't see any delay being good.
