- Get perfectly symmetrical brake / shift levers / brifters on your road or gravel bike. Eliminate the guesswork by aligning each degree of freedom separately. No special tools required.

The level of spatial awareness in this video is fantastic!
haha, glad you can appreciate on a nerdy level
I'm OCD to an extreme. Thanks again for a solution to this PAIN in the neck task.
Ha! Hopefully some will find it useful.
Great comments - I learned some new tricks. Yes, asymmetry drives me insane anywhere on the bars, beat it the angle of hoods, misaligned hoods, or bars that are not pointed more or less exactly straight ahead, so know that you're not the only one.
excellent tips! I love your sketches, makes it a lot clearer. thanks, very useful.
I'll consider the sketches to be my 'value added' to the community 😆
Brilliant! So helpful. Thank you.
Love the content your channel! 👍🏻
Nerdy and bike loving! 😉
Ha, thanks. Welcome!
Kudos. This has been bugging me to no end.
damn, I searched for this method for such a long time!!! CZcams finally guide to your video clip in 3 years!!!!
Bye the way, thanks for your very useful video. I will try coming weekend for sure!!!
So awesome to see someone who's as OCD about this stuff as I am. Thanks for the great content!
Haha nice
Very nice video, thanks!
Yay!! Bloody good effort bloke. Your channel is a really good source of considered information. Thank you.
Too kind, thx for the feedback!
@@TheBikeSauce No worries! Love your work.
A variation of this is the "falling horizon" method, whereby you look at the hood tops from behind the stem and move your head down until the handlebar obscures them (the hoods falling below the horizon). If one drops below the bar first, it's not level. No string required, and no variance on string placement introduced.
Yes! Fellow bike nerd! I like it
Another great video!! Keep it up!!
Thx, will do!
*mind blown* would have never thought to setup the brifters this way. Fantastic option/method.. my OCD has always bugged me when it comes to this.
Nice! So it’s not just me.
Omg you just saved me. My levers were driving me nuts. Now i can sleep again :D
Subscribed... This issue has annoyed me for decades and this is the first time I've ever seen a tutorial that made sense for getting the levers height and rotation correct. I ride with my levers rotated inwards slightly and every time I get on my bike, I think that one of the levers is at a different angle than the other. I will now go see if that's the case! 👍
🤘🤘🤘
Thank you!
Thanks
best video on the subject so far. 😀 (imho of course)
🤘🤘🤘
Thanks for the tips! Looking at the diagrams had me feeling like I was in college again 😂😂😂
Vielen Dank!!!👍🏿
awesome
This is so great I’m glad I stumbled upon this. My question is in regards to body geometry as nobody is perfectly symmetrical. I’m wondering if it may benefit the rider to have more asymmetry on the hoods to accommodate for differences between the right and left sides of our body. Although it may not help as much for bike control it may help for comfort over distances. Just a thought.
Yea lots of people have argued that people themselves aren't symmetrical. But I still like my bikes to be... 😆 Would be interesting to know if fitters actually compensate for asymmetries of the individual. Kind of doubt it, but perhaps.
Printed scales on handlebars are often asymetric, misaligned or crooked ! ;-)
I really enjoy your content and thanks for explaining this so well. I couldn’t help but notice you have the Venturemax bars. How did you get your shifters over the bumps in the drops. Please share your secret ways as I’d like to fulfill my OCD ways;) Thank you for all your content you post!!
Haha yea it was a puzzle. I took the shifter bands all the way off and reattached them once they were in place
@@TheBikeSauce did you have to bend the bands open more at all to get them over the bumps. I’ve got the same shifters you do in the video and it’s so tight that I don’t want to ruin the bars.
I placed the Bike Sauce sticker on my water bottle perhaps 2 degrees off vertical and thought "oh no, Nolan will not approve..."
😆😆😆
Brilliant! You not only have clear understanding of geometry, you have a methodical approach to process and a gift for teaching. BTW What dropbars are those?
Thanks for your videos. They are very helpful.
Thx Stan! Teaching is my day job so I can see how it’d translate into these videos 😆. Those are the Ritchey carbon venturemax bars.
I've set the hoods to the same height and the same length from stem, measured at the top of the hood. This should give you the same angle I think but the thing is that there is actually quite a big difference. Using the method for this shown in the video I am also getting different values when I tried to set the same angle by eye.
Any ideas? Thanks.
Hej, whats the size of that venturemax handlebar? Thx
Very useful tips and techniques. Thank you for this video.
Symmetry makes the bike look great, but people should be aware that the human body has asymmetries. If you're setting up your own bike and you're aware, for example, that one of your arms is a few millimeters shorter than the other, a purely symmetrical setup may not feel comfortable to you. Those levers are geometrically "perfect" but your body isn't. Best to be aware of when to sacrifice geometric perfection for bike fit. Just a thought.
Totally agree. Others have mentioned it too.
Degrees of freedom🤤🤤 talk to me nice
I purchased a Poseidon X with flared bars. On my first ride i fell which pushed in my right levers. They are no longer symmetrical and I been trying to match it with the left for 5hrs now. My OCD so bad I was going to sell the bike and buy another one lol.
Lol. Glad you didn't
In what order would be best to have geometric amplification:
1 - handlebar alignment
2 - lever height
3 - lever rotation
Is that the best order?
That’s how I do it. Not the only way though as others have pointed out
My OCD fighting the advice from the bikefitter that says good ergonomics doesn’t have to mean symmetry
Haha yea. I prefer symmetry as well
Well.. after you've set z, by changing theta you are essentially also translating in z, thereby misaligning again. You might just pull it off with a road bar but with the flared geometry I just don't see how this could work
Astute observation! Yes there’s some cross-channel coupling which is exacerbated by higher flare angles. My work around in the video is to ‘roughly align the angle’ of the adjustment side before setting the z dim. In practice, the theta adjustment should be minimal, thereby mitigating any effects due to coupled channels.
What if you have one arm longer than the other? I tend to just go off feel and basic visual inspection.
Ha yea it's a consideration.
I wondered the same thing. I believe there are few humans who are perfectly symmetrical. However, I do visually notice when my brake levers or bag or something on the bars is not symmetrical.
Tough call. My personality would have me setup the bike symmetrical even if I am not.
This is a cool video but I find a bit pointless when we are all asymmetrical by nature. I just adjust it by eye and then just grab them as I would riding and adjust each one to my comfort.
Nice. Next up... how to wrap symmetrical bar tape 😩
Was thinking about it, but would be very niche!
Looking forward for you to be part of Alternative Cycling Network sir.
would love to be a guest at some point. Think this channel needs to find its ‘voice’ first 😆
Or just use a laser and two rubber bands with marks in the middle like normal people
NEVER score a carbon bar. It weakens it. Use a Sharpie instead.
I'd say that humans are not symmetrical, so just jump on a static trainer and position them in a way that feels good.
Hi! First of all, there is no such thing as "perfect" in engineering or in nature. In particular, bike fit can change on the same day due to differences in body flexibility, etc, so there is more of a "fit window," as explained in the book by Phil Burt. Finally, I also done this for a while, and I use my phone as a level for angle measurement, and height from the floor using a metal tape measure. You did not explain how to keep the string taught, by the way.
Херня полнейшая. Параллельность веревки зависит в т.ч. от поворота пистолета, а про доску вообще молчу. Все это реально проще выставить тупо на глаз, чисто посмотрев сверху и спереди, выделяя «контрольные» точки, которые должны быть видимы или нет с определенной точки обзора. Как вариант можно приспособить под это дело правило для петуха, заменив сердечник с резьбой под переклюк, на такой же, но с резьбой под якорь
