Well well well Looks like I have finally a justification to buy one of those wireless droppers 😏
Comment from : @rubenbentein

Just got an e-bike about 55 lbs and stopped by to figure which stand I want
Comment from : @dcrump

just finding this video today—excellent topic brbrI stopped clamping by the seat-post when i got a dropper as a result my work stand becomes less relevant as I have workarounds I use wheel stands front and rear for most work I use the Park frame work stand for drive train but rest the saddle on top of the massive Park stand clamp, which has a pretty wide surface I think I only use the clamp on the Park stand when I remove my fork to service Will hold it in the clamp by the steerer tube

What are you cooking up for E bikes? Lifting 80 plus pounds over and over is wearing on the back
Comment from : @thomashayden4522

good job boys great help
Comment from : @user-ny7ps1ij2t

Just need to know can you put it in the bike stand don’t need all the maths
Comment from : @dukemasters6829

Thx guys! now i can work on my new bike 🤘😄👍
Comment from : @trailbuilder5789

Lower seatpost clamping is safest
Comment from : @robertmcfadyen9156

i always use the main post and never the stanchion I figure having the bike weight pulling down the from the stanchion would mess it up

THANKS GUYS YOU ARE THE BEST I HAVE 60 OR SO POUND FAT TIRE E BIKE WITH A DROPPER POST I HAVE THAT STAND YOU WAS TALKING ABOUT AND I SURE ENOUGH WOULD NOT WANT TO HOOK IT UP WRONG
Comment from : @mrd6093

thanks, just brought my bike stand and this was great in providing me answers to my concerns when working on my MTB
Comment from : @AdF-RepublicOf6

I'm clamping my dropper below the section that is moving up and down, just to be safe I don't care if it may be ok to clamp the upper section because I have no need to I only need to clamp at one spot to hold the bike, so that's why I choose the most solid part where it doesn't matter if it get scratches or not
Comment from : @a8f235

I was looking into buying my first bike stand and was worried about the clamping forces on the dropper Guess I have nothing to worry about
Comment from : @user-rj9ui3sz8u

Thanks guys I have the park tools stand and have been clamping my heavy (24kg) emtb on the frame, as I was lead to believe you should never clamp the dropper I always wince when putting it on the top tube No more, seat post from now on Thanks from the UK Great video
Comment from : @steviebye1

what for clamping seatpost from madone SLR?
Comment from : @arisetiawan7377

Well thought out gents Appreciate you crunching the numbers for us Now if I could just get my Fox transfer to stop sticking 1" from the top LOL 😆
Comment from : @mikeb3918

dying laughing thank you guys! can't wait to order my diy park tool post
Comment from : @holliskeith

Ok for 27 KG EMTB Alu Frame with dropper Post ? Or better Remove Batterie before (-4,x kg)
Comment from : @marcelfritz4130

Fantastic! Thanks! I am just about to get my first carbon-framed bike and only just considered that I should not clamp the frame It's really good to know from the experts exactly how to clamp the dropper post without causing any issues
Comment from : @chrisw3327

I am wondering if this kind of thinking is the same with my concerns for putting up a 80+ lb fat tire ebike I am worried the bike would be too much front heavy twisting pressure to clamp the bike by the seat post Going by this video, it should be fine - correct?
Comment from : @TylerFernandes94

I've always clamped my frame instead of the post, even before having a dropper Glad to know it's safe anyway
Comment from : @john_john_john

Is the same true for Carbon fiber Seat posts?
Comment from : @jedisdad2265

85/128th oh man no one can tell me that these imperial messurement is easier 🤮🤷 sounds much easier than 7mm 😂
Comment from : @andreasbrandstetter9221

how about ebikes?
Comment from : @btothey7243

Man oh man, fun and informative
Comment from : @MaquinasDePalomitas

Thank goodness for fast forward
Comment from : @tahoekayaker

Awesome Well explained
Comment from : @leroyholmes9131

Great video And thanks for the metrics 👍🏻
Comment from : @RedZangief

Love this videoSo refreshing to see someone showing the number and the actual engineering involved Love it 🖤
Comment from : @Peterthegmtb

Nice effort, and good to know I can hang it on an extended post However, I think I’m missing part of the evaluation, namely the part where torque forces on the post seal apply, and the forces in the length of the post Based on the weight allowance of a rider, and the angles of the post, I would imagine the torque on the seal cap to be negligible in comparison Likewise, I think the forces in the length of the post (rider weight) to be also not high in comparison But the construction vertical is very different It is not designed to have a tensile force acting on the post So to know if you can hang the bike on the top part of the post, you really need to know what tensile forces the post can takebrSo personally I would probably not hang it on the top part without knowing As demonstrated in the video, hanging from the bottom part of the post should be fine

What about clamping a $30000 carbon seatpost?
Comment from : @jimkodet7908

What about a 75 pounds eBike?
Comment from : @Zetler

Love these guys and Part Tool kit
Comment from : @ianbarber6463

Your welcome for clamping Thanks for being a entertaining and informative duo!
Comment from : @tubesockets120v

What about using a top tube adapter, like for putting the bike on a trunk rack? Can the dropper post handle that?
Comment from : @Jason-tr2pt

Thank you I was worried about this
Comment from : @ericzingeler7140

11:00 there's your answer :)
Comment from : @its_matt_long

Thanks for the video I have an S Works Turbo Levo with electronic dropper Any recommendations as to how and where to clamp my Park Tool stand? Thanks
Comment from : @rsayagues

"Please clamp" LOL — If this is a Jeb reference, you get a like just for this dumb joke
Comment from : @PellyAaron

lol the metric numbers given weren't all that usable to someone familiar with the system
Comment from : @callumcarscadden4865

How about with a 55lb ebike and a RockShox AXS dropper?
Comment from : @robrider838

Outstanding
Comment from : @rtmunro

TL;DW at the 11:00 minute mark
Comment from : @katakis1

So most people think the argument against clamping the stanchion is that it’s too sensitive too be clamped? My thought on clamping there would be that it would damage the mechanism because it’s not intended to be used in that fashion

Is it ok to clamp the bike by it's frame?
Comment from : @MM-qv5lf

Bike 🏍
Comment from : @jinkslate4761

Hello guys! I have a FAT HS Ebike that weighs close to 100 lbs with accessories I need a repair stand to handle that, any recommendations?
Comment from : @rightpassage

It gives me anxiety seeing a dropper clamped on the extension
Comment from : @RealMTBAddict

Thanks for clearing out this myth 😊 I always tried to avoid clamping to dropper, but clamping to awkward points Now it’s clear!
Comment from : @tolgaakyay

How do I clamp a three wheeler
Comment from : @williamwallace2951

Thanks guys you thoroughly answered the very questions I had!
Comment from : @bengeist3227

This is awesome I appreciate you going into the math and actually proving that the bike will be fine Too many sources just estimate and don't PROVE that the bike will be fine I have no room below the collar to clamp, so this makes me feel a lot better
Comment from : @ryangranet426

Nice to have some official tech to point customers too if they say anything :D
Comment from : @kingcardbeard1471

Great video guys! I appreciate the measurements, loads, and comparisons
Comment from : @kevinadam327

Personally I rest the front wheel on the ground in most situations when the seat post is clamped in the stand It’s just more stable and less torque on the work stand also
Comment from : @michaelmann3636

That was actually really useful and weirdly entertaining - maybe I need to get out more ……
Comment from : @GreyingNomads

The only stress that didn't get mentioned that I feel would be worth it, is side to side rotational
Comment from : @dlooney

Great video - you answered my question
Comment from : @WBOS72

Once clamped does the length of time it's on the clamp have any affect? I have the New Bluetooth post
Comment from : @tonyfernandez6178

Manufacturers simply advise not to do it, or to be cautious I think if they fully endorse it, they're worried some yahoo might get the wrong idea Common sense isn't so common sometimes A big butt on the saddle subjects the post to much higher forces than a stand will typically impart
Comment from : @seitenryu6844

Kudos for how you handle the issue of metric vs imperial units So many creators are positively passive-aggressive is their use of metric units, even when the majority of viewers are more familiar with imperial units We’re here to learn about bikes (or whatever the subject of a video may be), not receive a scolding about the continued use of imperial units
Comment from : @DrSchlitz

Thanks for making this video
Comment from : @datjeepcray4188

I cant do that clamping on my Fox kashima coat
Comment from : @koukimonzta

Give him the CLAMPS!
Comment from : @_MrSnrub

I literally buy park tools whenever I can because of the mustached man
Comment from : @nebno6

Thanks for the videos guys! My bike is soooo happy I watch you videos and use the great knowledge I learn here to keep it clean, maintained, and ready to rip every ride!
Comment from : @seany2345

After working on my own bikes for years, i’ve never had a dropper post mainly for the myths this video has explored Recently just got a bike with a dropper, and the question raised its head again Needless to say, Park Tools have given reasoned and logical explanation, and put my mind at ease Thank you so much This video is invaluable Another reason to choose park tool thanks guys 👍🏻

What a great video guys this clears up a lot of debate in the shop! Changed my mind about this whole controversy Thanks!
Comment from : @kenhuffmire9134

Brilliant video guys, thank you!!
Comment from : @michael_emtb

I have a 52lb e-bike Should I clamp the seat post or the frame?
Comment from : @rjmidd2650

I'm clamping right now
Comment from : @TheHeadlessHorseman

I'm going to stop twerking and start Clamping
Comment from : @MrA8figureman

subscribed ;) clamping a bit easier after this ;) big thx
Comment from : @thekjub

GREAT info, TY!
Comment from : @Superrun357

Re seat post collars - I've changed from standard collar on Scott scale labelled 4nm to a hope collar labelled 8nm, should I have stuck with same nm collar as stock or are all seat post forces equivalent (the hope is approx double width of stock)?
Comment from : @ByronWWW

You guys bring out my inner geek I love this kind of info
Comment from : @SargeHitch95

My post is raised to full height I can't clamp below collar; I'm clamping above the collar My jaw covers are clean and are clamping the upper stanchion My bike is hanging level brbrQuestion: is using my repair stand as a substitute for a bike stand an acceptable storage method for my bike, or is this ill-advised?
Comment from : @sebmcasa

I still don't feel like doing it, I think vacuum can occur even when the dropper is all the way up, creating air bubbles in the system, especially on a heavy e-bike
Comment from : @LinkinPark4Ever1996

These guys do not have their physics and units down xD Love them, but "How many thousands of pounds of pressure per square inch" xD Units are hard
Comment from : @taneliharkonen2463

What about forces when you are actually working on the bike ? If I work on BB I may apply more forces and weightstill not sure what’s best practice🤔
Comment from : @hubertplaideau5252

Reverb, $350 Evil Insurgent/Wreckoning frame $3300 It always was a no-brainer to me Clamp the cheap part
Comment from : @badbullymtb175

This review reminds me of the movie "Fargo"!
Comment from : @LarryRichelli

Quick question: Does this go for a 23kg EMTB with carbon fibre frame and dropper post to? :)
Comment from : @KristianBerg93

Thanks for the great info and explanation Recently installed a dropper post, don't have enough room under the collar, so this helped a lot
Comment from : @DGmtb51

Awesome, perfect and to the point with some engineering data (And that you did imperial and metric)
Comment from : @TheHolymoses

Well that answers my concerns about my dropper Won’t be wasting time clamping to the frame near the seat post anymore
Comment from : @MotoErgoSum

Lockjaw is especially bad, but mostly for your teeth
Comment from : @platypushatstand

I always clamp on the Top Tube
Comment from : @alidarivera5836

Hello,brbrWhen measuring the torque at the clamping jaws exerted on the seatpost would the moment arm of the bike not multiply that figure massively? I'm not an expert or trying to piss on anyone's chips Just a questionbrbrThanks for doing the video
