Comments on: Lauf Patents an Infinitely Engaging Rear Hub Design https://bikerumor.com/lauf-rear-hub-patent-design/ All the best cycling news, tech, rumors and reviews Fri, 15 Nov 2024 17:49:52 +0000 hourly 1 https://wordpress.org/?v=6.6.1 By: Tom Wenzel https://bikerumor.com/lauf-rear-hub-patent-design/#comment-3530747 Fri, 15 Nov 2024 17:49:52 +0000 https://bikerumor.com/?p=372540#comment-3530747 I am still puzzled by $himano’s inability to bring their Psylence rear hub to market a few years ago. I rode a bike outfitted with one and it was amazing. It apparently had longevity issues, but no doubt they could’ve worked them out.

I don’t think you read what I wrote. I said that DT was a low-drag system, especially with their low POE ratchets.

You do realize that this is just a patent*, not a flushed out product, right?

just all the shards to sweep up when you pull an inevitably failed one apart.

with discrete spring elements, and not every pawl edge exerting its own force.

Why are you spending so many words on what is an obviously flawed engineering kite-fly?

DT’s Star-Ratchet took Gold in last Olympics, so don’t think drag was a factor.

Perhaps you should revisit the physics in terms of all the factors that influence drag in a hub. The number of POE is not the only factor. Look up “normal force” and then look up the equation for friction force and see how the normal force influences the friction force. It’s irrelevant what you’ve seen, especially since you haven’t seen this hub. After all, your opinion isn’t an objective measure of anything, and since such an appeal to authority is lame. Let us know when you test this hub. I hope you don’t design bikes and use “one-factor only” physics and engineering.

Oh, BTW: loads of people have claimed to have seen all sorts of things and then tried to use those claims as proof of something: Bigfoot believers, Flat Earthers, ghost hunters, etc.
