LH Thomson stealth dropper seatpost with 27-2 option

Thomson’s been teasing and testing their Covert stealth dropper posts for some time, but like with the original, they’ve used those days/weeks/months to make sure they’re gonna hold up to their reputation for bombproof quality. Now, finally, they’re here along with the 27.2 external dropper.

Despite just hitting their docks, the Covert posts are moving quick. They’re seeing more movement on the 30.9 size and are out of stock at their HQ, but there is currently stock at their distributors (BTI and QBP). The 31.6 have higher stock both at Thomson and in their distributors. The 27.2 dropper also started shipping recently, hitting distributors last week. They don’t have the Covert stealth routing option, but they are one of few options for bikes with the thinner post diameter.

Retail on all three of these are $479, about $30 more than the externally operated 30.9 and 31.6.


All of their dropper posts get a full 5″ of travel, for now. Thomson’s David Parrett says they’re looking at options for having a 6″ travel option and finding ways to limit travel for those that don’t want or can’t use all five inches. They’re also talking about a “comfort” dropper that would have a small amount of suspension built into an otherwise functioning dropper post. And that Pavé road dropper post? They’re still working on that, too, and the non-bent setback seatpost we heard about is in testing.


For stems, there are three new sizes available. The 0º x 60mm is a blocky looking one like their 50mm DH looking stem, and the new 10º x 70mm and 10º x 80mm look like the traditional X4 stem, but provide a +/-10º rise. (stem shown above is 100mm, the only pic available immediately)

They’re working on a 0º x 40mm, too, but ran into some machining delays. Look for that one soon.



  1. The 60mm stem has been in the wild for several weeks…it’s as heavy as a cheap Truvativ 60mm, should have been machined like the 70mm X4.

  2. I don’t quite get the Thomson mystique. Broke the faceplate on my Thomson road stem and the cradle area of a Thomson seatpost on the same road bike, done. I weigh 150lbs. Machined parts look cool but in structural area I’m sticking with forged, lighter AND stronger.

  3. @Jeb- I’ve been riding/selling Thomson since the beginning and have only had a few problems. All were taken care of by L.H.. I’ve seen the same problems from other companies, whether forged or machined.

    My shop has literally sold hundreds of posts and stems. Very, very, very, few have issues.

    For me, Thomson makes good stuff. The key is following the manufacturer’s torque recommendations. Just sayin’

  4. Jeb-I’ve been using thomson stuff since the beginning as well. Only way you could possible break anything at your weight is if you ham fisted the bolts with a cheater bar. Or as we say, over tightened. In bike shop speak: user error.

    I’m 220-250lbs in the last 7 years depending. Always on Thomson. Never broke a thing. Have Thomson on 5 bikes right now. Only brand I recommend. Best ratio of inexpensive, light, and strong on the market.

  5. Couldn’t have said it better myself @WannaBeSTi. Seen a lot of crap from a lot of “top 5” companies over the years but never had any real issues with Thomson products at all. I saw one broken seatpost from a crash but the rider had a broken clavicle and the tree was missing a ton of bark…even then Thomson sent out a replacement within a week.

  6. I’ve been using Thomson for over 14-years, maybe longer. Never had an issue. I’ve always weigh more than 150-lbs. I ride both road and off-road. There parts are some of the best and they don’t appear to try to be the lightest at the cost of reliability.

  7. ive seen the odd faceplate crack here n there. and a couple broken saddle cradles. most were very old, most of the riders were corrosive sweaters. still, as a percentage of what’s sold, maybe 0.01%.
    on top of that, thomson makes every piece available, and at a dirt cheap price. arent the face plates like ten bucks?
    it’s also all made in the usa, including the hardware i believe. that’s kinda nice too.
    most carbon posts are heavier than their masterpiece too…

  8. “never had a problem with” coming from shop mechanics is not a good way to justify purchasing overpriced stuff. no one will say it outright but most custys buy thomson because of a vague “it’s nicer” and looks better.

  9. Until they get a LEV style cable routing on their external droppers I will pass. Might take a look at their stealth dropper though….after a couple years of guinea pigs testing reliability.

  10. @padrote, actually that is a VERY good reason to justify a purchase. A good mecahnic will have his hands on more bikes in 1 week than you will.in your whole lifetime. While engineering creates better parts, real world testing and use finds the flaws in concept/execution. Its often the mechanic (if a good one) that finds these flaws. If the home mechanic ‘– like the guy who broke both stem and post — Is having problems it’s likely user error. Buy a torque wrench!

  11. +1 for a 5 or six degree stem AND a thomson setback post that has a straight shaft. thomson said a bit ago that that type of post was in the works. anybody with any ideas on this new set back post availability from thomson??

What do you think?
