While bikes have become ever more advanced (and expensive) over the years, it seems increasingly strange that something as fundamental as getting your bars aligned is still done by eye. Even for an experienced mechanic, bringing the bar precisely parallel to the fork crown can take several rounds of trial-and-error. Personally, I'm often left with a nagging doubt that it might be a few degrees off.
Dead Naught Tool Co. hopes to change this with their handlebar laser tool. Laser-based tools for aligning handlebars have existed before, but they tend to rely on the front tire as a reference point. This tool straps onto the handlebar and shines two calibrated lasers to project the plane of your handlebar onto the
fork. These can be lined up with the fork's crown, arch or axle in order to ensure the bar is straight, before tightening the stem bolts.
The tool is the brainchild of pro mechanic, Derek Corbett. "I believe the front tire is a poor thing to use to align the handlebar as tires are rarely straight or in dish," Derek explains.
It sits on the handlebar with two machined acetal vee-blocks (which apparently won't scratch the bars). It's powered by two AAA batteries, which should last for 40+ hours of continuous use (over a year of regular bike shop use). Custom electronics mean the laser intensity won't fade over that time.
Dead Naught Tool Co. is launching on
Kickstarter with a campaign that ends on September 11th. The handlebar alignment tool may just be the first product from the company. "I've got a new tool in the works that will allow for a wide range of adjustments, with one laser-based system," Derek tells me.
Step 1; loosen stem bolts
Step 2; loosen bolts more because they are not loose enough
Step 3; realize bolts are too loose so tighten them up
Step 4; straddle bike with one eye closed and twist bars, bar don't move easily because bolts are too tight now
Step 5; twist bars only to over-compensate cause bolts are too tight
Step 6; twist bars back the other way only to over-compensate
Step 7; get off bike and go around to front and straddle front wheel
Step 8; bars look square WTF
Step 9; re-straddle bike, nope bars are not square
Step 10; go back to straddle front wheel and over compensate twisting another 3-4 times
Step 11; get back on bike in your 'attack' position to make sure it feels good while wiggling your bars back and forth a bit to make sure they are square
Step 12; bars slip and get mis-aligned whilst doing this
Step 13; &$(# it, get it close and tighten up your stem bolts
Step 14; realize you are hyper aware of bars being .0001 degree off and it's screwing with your head for the first 1/2 mile
Step 15; ride it like this for 6 months and never think about it again
But maybe it's just me?
vote this good man up!
This tool, that electric bike stand, and all these fancy trinkets that only a dentist would own …
Sometimes I wonder where we’re going with all this junk.
- snug the headset down to where the bar can still move a touch
- drop the saddle and straddle the bike
- lay a straight edge across the top of the stanchions (I have a yellow level)
- align the bar to the straight edge by sighting on either side of the stem
- tighten down the headset
- carefully swap hex keys and torque down a stem bolt to make sure nothing moves while you get off
- tighten everything up

Step 1: Try to align bars
Step 2: Give up and let my wife do it
Step 3: Profit
Laying a straight edge (or anything long and straight) against the stanchions like mentioned above is the trick. Big long edge to sight the bars against. Minutely accurate, fool proof, cheap and simple.
From there straight to Step #15.
How far off do you think you were?
"Really? Are they ill-tempered?'
"Absolutely."
"Oh well, it's a start."
Cons: cant use by airports
Heres the last one

It feels as if magnetic pedals are getting closer to solving these problems. I'm not saying they are there yet - but each iteration seems to get better/closer.
But can it align a Johnson rod?
Hilarious. You're a funny guy.
And I appreciate your concern about my fingers, but I can safely assure you that they in no way are akin to sausages.
I have no idea what you're trying to say about stanchions. They're cylindrical and so are the fork lowers that they go into, so there is no alignment required for a fork stanchion that I'm aware of.
#2 insert key into keyway
#3 install top cap and tighten fastener
#4 tighten stem pinch bolts.
The keyway just needs a slip fit on the steerer to center up the key and the stem would be a slightly looser fit then tighten up to a interface fit when tightening up the stem bolts. It would definitely be a balancing act of tolerances but I do believe that's part of engineering and really isn't as hard as everyone thinks.
One morning in the tent I was handing her one of her socks and said "Why does your sock have an 'S' on it instead of an 'L' or 'R'?"
We've been doing this for hundreds of years without anyone I'm aware of complaining that "I wish I could align my bars even better because X bad thing happens or Y performance is left on the table". There's probably enough variance in manufacturing tolerances of the components involved in this device and bars+stem interface themselves that you won't be realizing anything over using your eyes. I don't understand the value proposition at all.
Have you compared the convenience and accuracy of this product to the method of aligning the handlebar to a straight bar held against the stanchions, as suggested in this comment section?
Park Tool and the like then sell some "bike specific" premium tool that said consumer buys, oblivious to the fact that there is a cheaper, better tool from Bahco or equivalent being sold at the local hardware store. You see the same with stuff like lubricants or bearings

Ive used this one at work
Get a straight stick or pipe (think broom stick) and a bungee cord. Lash the stick horizontally across the shock lowers or stanchions, tighten with bungee. Look from side to see how stick lines up with handlebars. If they aren't parallel, tweak.
Easiest to look "through" the handlebars to the stick to see if they are lined up. Trick is making stick level.
Could just lay a rod across the stanchions and sight down.

Obviously he's never seen me bungie a plastic box onto my handlebars if this is a better alternative.
Also, it $139 USD (plus shipping) for the Kickstarter if you want this over a couple of laser pointers and a roll of duct tape.
More lazers!
about this project-while we really like the
design, we have one question-Not sure if you
have got a patent lawyer…….?this process is
patented at this time both domestic for
20years- and international for 5, hate to be
the one to break this news to you…..we will
be contacting our lawyers Tuesday - again
sorry for the bad news Www.dnrdesignsllp.com
Then a buddy pointed out the "sight the back of the handlebars onto the front of the fork dropouts" method.

I’ll save my money for another set of tires
