Eagle Eye Laser Chain Aligner, Red Aluminum

This narrow chain aligner is a perfect fit for most 219 and 35 aluminum chain sprockets that are 4mm (5/32') thick. It's been redesigned in 2021! You can align your rear sprocket with the drive sprocket in just seconds. However, it doesn't work well with a rear sprocket guard and isn't suitable for plastic Extron or shifter sprockets. It's only for flat aluminum sprockets.

Using this chain aligner is a breeze. First, make sure your sprockets are the right type - flat aluminum ones that are 4mm thick. Then, take the aligner and quickly line up your rear sprocket with the drive sprocket. In just seconds, you'll have them perfectly aligned. Remember, it won't work well if you have a rear sprocket guard on. Also, don't try to use it with plastic Extron or shifter sprockets. For maintenance, keep it clean and store it in a dry place. If it gets dirty, you can gently wipe it with a soft cloth.
