Tune Spurtreu Perfectly Aligns Handlebars to Your Front Wheel – with Lasers!

A wonder no one had thought of it before! Really handy for shops.

Great idea, can’t be too hard to make one DIY-style for a few bucks.

FINALLY

Great idea, but that price… no.

hey folks, please keep in mind that this is being produced by a company that also sells a $240 carbon coffee mug…its safe to say they aren’t really looking to sell to the “eyeball it and adjust it” crowd on this one…

this doesn’t resolve the issue of relying on the user to ‘eyeball’ the centering of the stem over the wheel. This tool simply places a laser dot on the tire which the user must then ‘eyeball’ in order center the stem.

gr is correct a better version of this would sit on the top tube and square off the down tube to project a line that could be used to center the stem and the bars to the centerline of the frame

@MB, I believe that is a Litespeed head tube badge.

Dave B hits the nail on the head. I’ve seen the customer who returned to my LBS complaining about misalignment of her stem for three or four passes. The alignment was fine, but she probably chewed up more than the amount of time equalling $100 of labor until she stopped complaining. Plus, there’s the chance that she’s (falsely) assuming the problem is with the Wrench, not her cross-eyed alignment check. Doesn’t matter though; she’s telling anyone who will listen how terrible the mechanics at the LBS are and how they should take their business elsewhere.

I view this kind of tool in the same realm as the headset tube reamer/facer. Most of us don’t need it, but those of us who ream a headtube more than once every two or three years do can’t live without it.

Nice (if expensive) bit of for road bikes. Can foresee problems using it on new-fashioned short n’ stumpy Enduro (trademark) stems, though. And yes, if your wheel is crooked in the dropouts, it’s a moot point anyway.

Here’s a tip I picked up from somewhere.

Find something big and flat, like a nice flat section of floor.

Put the frame down on the floor so the fork dropouts and the front of the drop bars are touching the ground.

When all 4 points are in contact, tighten the stem,

I have a great technique to solve this problem: I align the stem with the front wheel using my eyes. Works great!

I do have a laser level for house construction projects. It will be trivial to adapt by just bolting it overhead, so it generates a nice straight line – to set stem saddle, etc.

But I can not imagine it making any appreciable difference over just setting it like I have always done it. Even when visibly misaligned, it still rides OK enough…

Or how about a plum line?

$100 could get me a shark with friggin’ laser beams…that’s ridiculous. It doesn’t have to be CNC’d, and the laser pen is what $5 at most? Also, this would be much more useful if it threw out a laser line like those tools at Home Depot.

Maybe at a shop you could show that off to gullible customers, but really not for any self-respecting home mechanic in the real world. I’m just going to use my laser pen and align it with the bolts on my stem, like I do to check my chainline.

I could be wrong but one dot does not make a line. A laser line along the tire might help this a little. The price wouldn’t be horrible if the product could ensure that your alignment is perfect.

i use a tile square laser level, about $40…

A piece of string works better than this, line the stem up with the wheel while keeping the string tight and use the eye. KISS

I like the tool. I think it would be helpful to many people/ shops. And not just as a gimmick. $100 seems steep, but most really good tools are expensive… Shimano SIS cable cutter MSRP’s for $85, Rock Shox 24mm cone wrench $35, Campag 11s Chain tool $250…

In my shop, I “think” I have the straightest eye for aligning a stem. I’ve have asked 4 other mechanics what they thought after I aligned a stem and got 3 different answers.

My conclusion, straightness is in the eye of the beholder. A laser could shut a lotta people up.

I hold the US patent for this tool

I broke my collarbone once, so i run my stem crooked so it feels straight

Aligning stems by eye is virtually impossible, due to eye dominance, and parallax… this is no news to shooters/hunters.

I bought this tool, and the bracket is fine, but the laser is a cheap POS. You can easily wiggle the laser in the tool. The laser is so cheap that it can bend and distort. I helped it by moving the laser up out of the tool and grabbing it by the cap… that helped. Some.

The problem with the tool is that you will drop it, A LOT. It is an odd shape. When you place it on your bike, you think it will stay put, but it doesn’t. Your wheel will tip to the side on the stand, and it will fall off and hit the ground… or several other similar circumstances.

I found a 20-Gauge Shotgun shell laser bore sighting too for $15 on Amazon, and bored the little hole out to take the bigger, more solid laser. It’s perfect now.

People that think $100 for a tool like this is “too expensive” and “overpriced”… are just poor, and would never buy a tool like this anyway, so you can disregard their pointless comments. It is America, and you are welcome to buy a $200,000 CNC Machine, hire a CNC Programmer for $100K a year, buy a building to put it in, and make your own!

For me, I’ve wasted days of my life aligning stems, and with this tool it is an instant problem solved. Leave the stem loose enough so it doesn’t “skip” when you try and move it, and just align the red dot and tighten the bolts. It took me longer to type how to do it, than it does to do the whole process.
