The Sniper Inox Laser Chain Alignment Tool makes drivetrain alignment quick and precise. Proper sprocket alignment is what keeps you from throwing chains, wearing sprockets unevenly, and stretching chains prematurely.
Clip it around the edge of your rear axle sprocket, and it projects a narrow laser beam toward the engine drive sprocket — when the beam lands right in the splines of the drive sprocket, your alignment is dialed in. An integrated flex switch turns the laser on automatically when it's seated on the sprocket and off when you remove it, and it runs on an included CR 1/3N battery. Comes in a durable plastic case to keep it protected in your toolbox — worth keeping a spare battery on hand too.
*NOTE: You must remove any sprocket guards to use this product. Only fits #35 and #219 sprockets, does not fit #428.
