This exceptional cassette is crucial to the unparalleled inboard and outboard shifting performance of the Eagle Transmission system, particularly under heavy load. The GX Eagle Transmission cassette employs a full X-SYNC design, ensuring that the harder you pedal, the smoother and more precise the shifting becomes. With a chainline of 55mm, this cassette reduces extreme chain angles throughout its entire range, resulting in improved precision and extended chain durability.

The optimized 520% gear range of the GX Eagle Transmission cassette introduces larger 38 and 44-teeth cogs before the 52-tooth cog, enhancing the gear steps in the low-end range. This configuration offers superior performance compared to the Eagle drivetrain's 10-52-tooth cassette. For effortless installation, the cassette is equipped with a clearly marked Setup Cog, making the setup process simple and foolproof.

The GX Eagle Transmission cassette utilizes a combination of Pindome design for gears 1-8 and a single-piece mini-cluster for gears 9-12. This innovative construction ensures optimal gear engagement, durability, and smooth shifting performance throughout the cassette.

Good light. Minor flaws.
Style: 180 Lumens
Good light, only flaws is that it didn't come in a box. It was just in a clear plastic bag. And batteries were not included.

Puts out a lot of light!
Style: 220 Lumens
I had to have an explosion proof light, and this one puts out an amazing amount of light! On flood light ( second push of button) it lights up an amazing amount of area around you. The spotlight will hit a tree in my back yard while standing in the front yard. Very impressive!

Very useful if you don't want to explode!
Style: 90 Lumens
Found the unit a bit difficult to adjust on the hard hat but got it dial in eventually. Also impacted by the need to mount goggles on the helmet, that might be rare, but this was my situation working around chemicals. nice and bright. batteries last a couple of days with intermittent use approx. 3.5hrs a day. A bit of a pain to unscrew the cover on batteries but that's the nature of the beast to make sure no sparks escape. Would highly recommend the product. Most other comparable products are around double the price. BTW, the packaging looked like the driver dropped it on the road and ran over it a couple times...but it still worked. UPDATE #1: After a few months of usage, the height adjustment is starting to fail. As I walk, the light begins to droop until it's shining down in front of me. Dissappointed that the adjustment didn't last longer. I might be able to discover a way to lock it back in, but have not taken the time to examine the mechanism yet. UPDATE #2 9-2018: The adjustment problem has now reach its ultimate end. The hinge on bottom has basically disintegrated. Now, when I put batteries in and tighten the screw, the bottom hinge pops loose. The product is no longer usable. The hinge is just cheap plastic, that is a shame, I kind of expected better from nightstick. However, it still seems to be the best option vs. price available so I am planning to order it again. Hope I can get 3 years of intermittent use out of the next one. I do really like it when it is working...lite and bright.
