Hahaha :-) best comment. I was thinking exactly the same. The next step is we need a global wide intervention from governments that set one global standard (like the USB-C standard).
Great video, but few missing things noted : 1) do you lubricate them (axle itself and hub inside?) 2) how end nut is usually fixed to frame/fork - ex. Focus R.A.T. nuts vs others 3) how to prevent wheel theft with this new non-standard axles
So why did I just watch a video on Peak Torque that stated that through axles are not axles and serve the same function as skewers, to clamp the axle (axle in the hub) to the dropout. According to PT the through axle should not Cary any vertical load. The load should be carried at the dropout through friction betweed the hub axle and dropout. He also stated they need to be tightened more than a small tool can do, therefore they are generally under tightened. Correct me if I understood it wrong but this video kinda contradicts that one.
30 seconds in... 1) Most through-axles are no more axles than are QRs. They perform the same job as a QR skewer: they clamp the wheel to the bike. 2) QRs do NOT simply "come loose". When properly tightened, a sufficient force must act upon the lever to overcome the cam-over. 3) Yes, QR skewers are flexible, but this isn't a negative. QR skewers, just like through-axles, exist to supply a clamping force. QR skewers must be strong in tension. Think of the vertical cables on a suspension bridge... Do we pooh-pooh those cables because they can flex? Should the cables be replaced with steel pipes? I'll probably never purchase a component from The Roberts Axle Project, thanks to the incorrect assertions, implicit and explicit, found in this video. Bike Rumor is now on my list organizations that can't be trusted to provide reliable information. Congratulations!
Thru axles don't always clamp the hub in place. Fox Float deliberately avoids clamping the hub, because if the hub is even slightly the wrong length for the forks (which may have tolerance variation from the standard 110mm) the fork friction and wear increase.
Good, I need to learn this because my son's bike has a quick release that can be set up as a thru axle, but the thread is different than my thru axles...I wish mountain bikes were simpler....

Great brief and informative video. To the music haters, if you're looking for good real content, you can ignore the music for 5 minutes. If you're looking to be entertained, that's something else. My only comment: It's dumb to say QR skewer is less stiff as a thru axle! A QR skewer serves to clamp the hub between dropouts, not to provide support for the wheel when mounted. Enjoyed the video nevertheless. Thank you.
Through axles aren't axles. They are compression bolts. Their job is to compress all.components together.The axles are inside the hub, within the bearings. If you pull out the bearings you will see what is really going on.
Great vid. Thanks. Question/observation- Old skewer hubs- the skewer goes through the axel. To remove axel u must remove the skewer and then axel locknuts. Most thru axels are same way. The thru axel is not the axel as there is an axel inside the hub that can be removed after removing the misnamed “thru axel”, no? So bike industry calling the thru axel an axel is same as calling skewer an axel. Si or no?
QRs do not come undone, unless you don't tighten them sufficiently - just like every other part of a bike. In 50 years and tens of thousands of miles riding bikes fitted with QRs I have never had a QR come loose. Also the stiffness of a QR skewer is completely irrelevant, they don't support the weight of the bike, because as you pointed out yourself, they're not axles.
Please help, I have a mtb 29r with 1 of these axels only I was having a lot of trouble with mine and my derailer rats around and I couldn’t get my wheel off at all now at Saul’s on salty the Allen keys, just go round and round in it and can’t get my wheel off whatsoever. Any ideas how to get it off please?
I have checked my front hub, and I saw some movement at the both end of the hub (right and left side). Is that means that my hub are broken? Since my bike is new
Excellent video; thank you! I’ve got a thru axle on my 2019 R5 with DT Swiss 1350 clinchers, and the skewer doesn’t stay right on either tire. Unreliable, as it loosens up on me. Not even bike technicians and bike fitters are able to make sense of the particular kind Cervelo decides to toss on there. It’s got to be a warranty item !?!

For the QR that never come loose that's good, I think people are more worried about them snapping HAHA from a 5+ foot drop. But also I think there's more stiffness, not that I like stiff.
Nice , as soon as I can justify changing my existing button though axles to something hand made And quality like the robert axle ,I will totally jump on that . Ask them to anodize other colours that may entice some people , I know I would be down for a blue one
I have a 20x110mm fork and uses thru axle but no lever or not quick release and I want to change it with the one with a lever for quick release access. Which or what thru axle should I go for? Can you guide me? Thanks for the vid.
i used motorcyle axle 12mm solid bar for front wheel bike because i need the bolt nut lock on the other end. robert axle is lack of information & dimension layout of each of their products. i have marzocchi fork with 20mm i convert it into 12 axle bar so i need a lock on the other end, outside to outside fork dimension is 165mm
Trying to learn if the thru axle system relies on one end threaded into fork (or in my case, custom single-sided setup). I want to thread my own drop-arm for a cargo trailer wheel axle, and can't tell if a 20mm thru axle must thread into the arm, or if the ~20mm of dimension thickness of my drop-arm is sufficient to cantilever support the axle and wheel. I would think that a tight machined fit is as good as a threaded fit, as far as the strength of the cantilever, and only the thickness of my drop-arm material really matters?
Sorry I could only watch half of this because of the irritating loud music, I was trying to listen to what you said I never knew there was so many hubs and spindles, I will find out somewhere else
Just got finally a mountain bike. It come with a thru axle. My quiestion is ( the rear axle treed doest go all the way in to the treed itself in the gear side of the frame before i cant tighten up the axle? It seems that i goes in only half the way... Is it normal?
Thru axels took cycling technology backward, plus it made it more expensive. Do I choose complexity and proprietary sizes and threads, or do I choose standardization? If skewers are good enough for racing in the Tour de France or in Paris - Roubaix, then why have this change that doesn't offer any meaningfull advantage, only headaches.
Hi . I don't know much about bikes . But i wish to put two (2) wheels in front of a bike (folding or bmx) . Is there an axle that could make that possible ? Hoping for your kind reply . New on your channel . Liked & subscribed . God bless
Fantastic video logically and simply laid out, thumbs up from me. But it missed the biggest question of all. How do they work? what actually spins? how does an axel that seems to be going in easily without any friction like you showed, engage the pressed-on bearings on each end? Nobody shows this, everybody avoids it, I suspect is because nobody actually knows.
Oof. When you realize thru axles are not axles either. They preform the exact same job as the quick releases minus the cams and forgo the replaceable nuts. They both compress the bicycle frame to the actual axles. Only advantage of thru axle is it stops rare wheel ejections on some dropouts with disk breaks when they were not tight. Much rather replace a nut then a frame if it gets cross threaded.
The Industry 9 hubs shown here are very beautiful. Although I much prefer Chris King. They've been around longer. Lots of the info shown here I already knew. Unfortunately I've never ridden a thru axle bike. In all my years of riding, I've never ever had any problems with any quick release. My only concern is how quick release and thru axles affect disc brakes and there performance. Thanks.
is there some way to put 142mm thru axle rear hub to a none thru axle frame. being more especific, like adapting a skewer into a thru axle shimano xt 142mm 12 speed into a trek marlin.
If the dropouts are 10mm, that would require cutting, and that might weaken the frame significantly. Is there enough material to take out 1mm all around?
What happens when you damage or strip the thread in the frame? You mostly have to remove the wheel on the go due to punctures etc. where you’re in a world of stones, mud and grit. The potential for thread damage must be high.
Sigh I just bought a frameset that uses thru-axles and am realizing from this video that I now own a bike using an immature technology. In twenty years if this bike needs a new hub, it might mean finding a machinist or scrapping the bike. Having initially gotten into bikes by tinkering with 35-year old 3-speeds (which I guess are now 50-year-old 3-speeds), that's a bummer :(
I think you'll be very lucky to find a hub to fit in ten years, let alone twenty. Especially if it's one of the proprietary "nearly-but-not-quite-boost" hubs like Trek's Boost141.
@@IanJones-ht3kk Sigh yeah. To an extent, all hub designs are ephemeral. My 1974 Raleigh Sports is running its original front hub for this reason (narrow spacing) even though it's in imperfect shape. The rear has been running a nice 120mm hub as a single-speed conversion for the last dozen years or so - which meant cold-setting (bending) the rear triangle. That said, 100mm OLD front hubs and 120/130/135mm OLD rear hubs of a plain (bolt-on or QR) design have had a very good run. I suspect those designs will have replacement part support for a long time. This other stuff...we'll see!
When you finally find a "no BS video" that goes straight to the point without wanting to sell you 11 products before the ad spot comes, you realize it was A TRAP and get lobotomized by background music....
Because everything in cycling needs to be stiff. Unless you have a compliant carbon fibre frame. QR skewers were stiff enough, i.e. they must have been more compliant than thru axles. BTW does Eddy Merckx still have a bike factory? He could produce a range of bikes that have wheels with Thru Axels.
Checked out the website and nothing for an e bike it seems so I call BS on this video. I am looking everywhere for a rear axle for mine to upgrade my e bike to a 10 speed so I have less strain going uphill the problem is i am having trouble finding a solid axle with a 90mm bearing spacing . Quick release are dangerous on e-bikes and it looks like I will need to get the metal stock and either a machine shop willing to do the work at a reasonable price or get a lathe and do it myself.
Peak Torque would like a word. They're not actually axles. They don't provide better clamping force than QR's and they are costly. Sure, they offer repeatable location for disc brake bikes, and are easier on carbon dropouts, but that's about it. The bike industry has successfully sold you something that is arguably inferior to a QR, is less expensive to manufacture, and costs the for consumer more to replace. And we eat it up because 'fatter must mean better'.
I love thru axles and in my own opinion it's better than quick release. The quick release is subject to theft,while thru axles truly not subject to wheel theft.
HAPPY Multi-Purchase Customer here - Great Products, Service & Support......BIG Plus = their website can walk you thru finding the right Axel too - no connection except for buying & using on several bikes
It's worrisome to know your understanding of Thru Axle is all about the rod with threaded end. What Thru Axle is, in my opinion: 1. It's spelt Thru Axle with uppercase on both words, as it is a marketing term, eg. 'S'ram 'F'orce. 2. Thru Axle is a SYSTEM consists of: - Forkends with complete circular hole of closed ends (no dropout on all latest models) and this is the primary requirement, - A modified QR hub with shorter axle (yes that's an axle) in pipe form with larger hole throughout (except one make), - A large diameter (12-20mm) rod with threaded end (of which you call it thru axle) forming inseparable structure consists of hub axle, fork, and this threaded rod, - With or without a QR 3. Thru Axle system is introduced with primary feature to have a skewer to go through closed ends on forks, to eliminate potential catastrophic wheel separations during unbalanced or lateral dynamic shock, particularly under influence of disc braking. 4. There were myth saying that Thru Axle system is to improve fork stiffness against flexural twist under influence of disc braking, but the effect is minimal. Thru Axle system couldn't resolve impact of fork twisting due to disc braking, as in disc rubbing and disc warping persists regardless. Disc rubbing has to be resolved by wider brake pads opening. No solution as yet for severe disc rub or jam that comes after disc warp. 5. Since this rod is taking up vertical shear load (shearline between inner surface of fork and hub bearings) in place of the short protruding axle on a QR hub, it needs a larger diameter compared to conventional skewer of 5mm-thick. At the same time a wider forkends is required for vertical load bearing. 6. Since it is larger in diameter, manufacturers opt to aluminum pipe, as it is easier to deal with, compared to steel, while attempting to keep weights down. 7. In order to achieve similar clamping force as what's on a QR hub, a high tightening torque is specified (eg. 10-15Nm-ish). 8. As pointed out by Peak Torque and i agree with him, it is close to impossible to achieve specified torque, without long spanners, 9. In my opinion, the main goal of Thru Axle is still accomplished (even with a lower tightening torque) because the main goal is to eliminate wheel separation (through closed ends on forks) due to possible human error of not doing QR up adequately on conventional forkends with dropout. 10. Therefore some manufacturers still introduce QR on Thru Axle system, knowing the QR does not provide clamping force as high as conventional QR with skewer, considering consistency and ease of use.
How did Merckx, Anqeitil, Hinault, Indurain, de Vlaeminck, Sean Kelly, LeMond and thousands of others manage to have successful cycling careers without thru axles? The mind boggles nowadays. They didn't even have press fit bottom brackets. You have to feel sorry for those generations.
Isn't there a standards body somewhere that could stop the manufacturers from constantly coming up with all these "standards" for hub widths? It's a complete mess, even worse than the press-fit BB fiasco.
I was a little confused about thru-axles until I found this video. Now I'm completely confused. Thanks for that!
i love how this is not complicated at all. thanks bike manufacturer for giving us an easy 1 or maybe 2 axles to choose from.

Everything you need to know about Thru Axles is that you don't need them.
It was really funny that you compared qr stiffness with thru axle
I was thinking about going thru axle for my next bike. But good lord these are a worse headache than BB standards!

I love thru axles and in my own opinion it's better than quick release. The quick release is subject to theft,while thru axles truly not subject to wheel theft.

99.9999% of times, thru axles aren’t actual axles either
Why does the music have to be so LOUD, NIGH ON DEAFENING!
It's worrisome to know your understanding of Thru Axle is all about the rod with threaded end.
What Thru Axle is, in my opinion:
1. It's spelt Thru Axle with uppercase on both words, as it is a marketing term, eg. 'S'ram 'F'orce.
2. Thru Axle is a SYSTEM consists of:
- Forkends with complete circular hole of closed ends (no dropout on all latest models) and this is the primary requirement,
- A modified QR hub with shorter axle (yes that's an axle) in pipe form with larger hole throughout (except one make),
- A large diameter (12-20mm) rod with threaded end (of which you call it thru axle) forming inseparable structure consists of hub axle, fork, and this threaded rod,
- With or without a QR
3. Thru Axle system is introduced with primary feature to have a skewer to go through closed ends on forks, to eliminate potential catastrophic wheel separations during unbalanced or lateral dynamic shock, particularly under influence of disc braking.
4. There were myth saying that Thru Axle system is to improve fork stiffness against flexural twist under influence of disc braking, but the effect is minimal. Thru Axle system couldn't resolve impact of fork twisting due to disc braking, as in disc rubbing and disc warping persists regardless. Disc rubbing has to be resolved by wider brake pads opening. No solution as yet for severe disc rub or jam that comes after disc warp.
5. Since this rod is taking up vertical shear load (shearline between inner surface of fork and hub bearings) in place of the short protruding axle on a QR hub, it needs a larger diameter compared to conventional skewer of 5mm-thick. At the same time a wider forkends is required for vertical load bearing.
6. Since it is larger in diameter, manufacturers opt to aluminum pipe, as it is easier to deal with, compared to steel, while attempting to keep weights down.
7. In order to achieve similar clamping force as what's on a QR hub, a high tightening torque is specified (eg. 10-15Nm-ish).
8. As pointed out by Peak Torque and i agree with him, it is close to impossible to achieve specified torque, without long spanners,
9. In my opinion, the main goal of Thru Axle is still accomplished (even with a lower tightening torque) because the main goal is to eliminate wheel separation (through closed ends on forks) due to possible human error of not doing QR up adequately on conventional forkends with dropout.
10. Therefore some manufacturers still introduce QR on Thru Axle system, knowing the QR does not provide clamping force as high as conventional QR with skewer, considering consistency and ease of use.
I am just thankful that this not in inches
Why does this useful video have a silly tune playing in the background? Got about 1/3 the way through and had to stop.
This music makes me want to steal an iphone
Nice
Let me save you the time. There are a ton of different axel lengths and widths …your welcome
Pointless solution to non existent problem
Everything you need to know except what they’re made out of
How did Merckx, Anqeitil, Hinault, Indurain, de Vlaeminck, Sean Kelly, LeMond and thousands of others manage to have successful cycling careers without thru axles? The mind boggles nowadays. They didn't even have press fit bottom brackets. You have to feel sorry for those generations.
A visualisation of the different lengths would be better, because of the loud background sound your voice is hardly comprehensible,
Isn't there a standards body somewhere that could stop the manufacturers from constantly coming up with all these "standards" for hub widths? It's a complete mess, even worse than the press-fit BB fiasco.
With all said what are the dimemsions ? None
