Tune Spurtreu uses a laser to perfectly align your stem

Make wonky stems a thing of the past with the Spurtreu laser alignment tool

You know how it is, you’re squinting through one half closed eye trying to line up the stem with your front wheel, but as soon as you get out on the bike you can’t help notice that it’s a hair's width out, and if you're anything like me you’ll have to stop immediately to straighten it.

So here’s a product that I’m amazed nobody has thought of before, the Tune Spurtrue, possibly the most elegantly over-engineered tool for the simplest task. It uses a laser to align the stem precisely with the front wheel, while the device itself sits on top of the stem and handlebars. Pretty neat, huh?

The Spurtrue is CNC-machined from aluminium with shaped recesses to sit over both the stem and handlebar, though it’s not clear what sort of compatibility it has with the plethora of stems and handlebars on the market. A laser pointer is mounted at the front and operated by a small button. Press it and a beam fires down, simply line it up with the centre of the tyre and you’re good to go.

Products bearing the Tune label usually command a high price but at £65 it isn’t wildly excessive. Okay it’s not something you’re going to use everyday, but for a professional team mechanic or a website with a high turnover of test bikes, it could be prove to be indispensable. We've just been on the phone to Tune UK distributor Poshbikes and they tell us they've had 100s of inquiries already about the Spurtrue., so it seems to have hit a nerve.

It will be available from next month, and you can place your orders now at, 01622 762055 and info [at]
