Do you remember the
Ceramic Speed 'Driven' drivetrain that first debuted at Eurobike in 2018? Well, a YouTube engineer has now created his own version that seems to be in full working order.
The Q is a channel run by an anonymous engineer who has previously created a bike
that use circular saw blades as wheels to ride on ice and a fat bike with Formula 1 tyres. Of course, this is a bit more primitive than Ceramic Speed's drivetrain, which is aiming to be fully shifting with even a full suspension mountain bike version in the pipeline, but it's also taken a lot less time (
and presumably money) to get to the prototype stage. Skip to 4:17 to see the bike in action.
| Imagine bicycle without chain. Can it work as well as regular one? Well.. let's watch this cool experiment and find out. Yes, this prototype works but definitely needs some modifications.—The Q |
Certainly misleading with a catch phrase of "Engineer Creates..."
synonym
noun
a word or phrase that means exactly or nearly the same as another word or phrase in the same language
Engineer Creates way to power car with Potato
Engineer Invents way to power car with Potato
Regardless, I don't disagree that the word Invent and Creates are used differently in common vernacular, but context matters....but to suggest they are significantly different is incorrect (aka wrong, errant, you can pick the word you want)
Did you two just become best friends?!
Prestige Worldwide!!
edit in case no one believes me - what are cars, magic? and they have freaking engines.
The SRAM/Shimano “duopoly” and Big Derailleur seems like the ramblings of folks who might be into far too many other nonsensical conspiracies.
We could ride bikes like this!

Here is directly from the WD-40 Myths webpage.
A Question of Lubrication
Myth: WD-40 Multi-Use Product is not really a lubricant.
Fact: While the “W-D” in WD-40 stands for Water Displacement, WD-40 Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal.
btw. recipe is kept in secret for over 60 years
Here is WD-40 company's description of the Original WD-40.
"WD-40 Multi-Use Product protects metal from rust and corrosion, penetrates stuck parts, displaces moisture and lubricates almost anything."
The shaft drive has quite a bit of energy loss compared to a chain (further exaggerated by an internally geared hub) - it feels mushy when putting any real power down. It also requires good lubrication to avoid awful grinding/squeaking noises (ours were loaded with grease), so this guys choice to leave it exposed seems prone to issues.
It's a nice solution for casual beach cruisers in sandy/salty environments. Or, maybe for fat bikes in super muddy environments for hunting/military use. Beyond that, it's hard to justify the energy loss.

What’s old is new again, indeed.
