"I've recently been using the RotaLuber, and it has truly made my bike maintenance routine better and easier. It addresses a challenge I didn't even realize I had. Keeping your drivetrain smooth, quiet and long-lasting is essential, and the RotaLuber helps do just that. With its precision design, the RotaLuber ensures that only the necessary amount of chain lube is applied directly to each chain roller, eliminating waste, amd minimizing mess. I love the adjustable flow feature, which allows me to customize the application based on the viscosity of my chainlube of choice. From now on, the Rotaluber will be an essential part of m toolbox. I can't imagine ever lubing my chains any other way. Highly recommend it for anyone who values their bike's performance"

Before this marvelous little device came across my desk, there were only three ways to lubricate a bicycle chain: Blow-N-Go: the 116 Drips method: or removing the chain for the Hanging Snake Cascade technique.

Hold my beer!

The first time I used the RotaLuber, I was almost disappointed by its speed and efficiency. I filed the squeeze-bottle with a half ounce of lubricant, engaged the tiny sprocket and follower guide with the chain, steadied the device against the derailleur and- bzzz bzzz bzzz- every roller was individually lubricated in a single revolution of the chain.

That was it?

Two thirds of the lubricant was still in the bottle., Only one and a half drops stared at me from the shop floor. My bike was clean, and a post inspection revealed every roller was flush with lubricant, So little liquid came off of the towel, I probably shouldn't have bothered wiping it down.

The miracle....

Additive manufacturing (3D printing) made this miracle possible. Squeeze the bottle, and the fluid travels down the core of the wand, were a rotary valve blocks the flow of lubricant until a pair of nozzles on each side of its four-tooth sprocket line up with a chain roller. The lubricant is directed to the only points where the chain needs the stuff, and then the chain slides over a rubber ridge on the follower that rotates each roller to disperse the fluid into the bearing surfaces.

Epilogue:

Who needs another doo-dad on their shelf? Yeah, that's what I thought too, so I left mister RotaLuber on the bench and returned to my trusted 116-link drip method. I didn't get past roller number 63.... Total Fan
