I hope they're thief proof.

People are picky about the way their bikes look and I think that color could clash with a lot of motorcycles vs a black or mostly black chain.

I suspect that these will turn out to be much like "maintenance free batteries." It's not that they are truly maintenance free but that they cannot be maintained - they have no caps to add water. So if that is all that is needed a new one must be purchased.

These chains have multiple failure points - seals mostly - and anything with moving parts is going to wear over time.

Very interesting and thanks

Great! I've changed and adjusted my share of chains, it's a nuisance and messy, but unless I'm going racing (with a sponsor) I'll leave those on the shelf and save a ton of money!

There are already countless chainless bicycles & motorcycles w/ electric hub-motors!
(I think some of them are series hybrids using engine or muscle power!)
I for 1, think all bicycles & motorcycles still using chains need to become history!

BMW was known for sealed shaft drives.....what happened? I guess the same thing as Porsche's air-cooling.
Also, look at the chain details, what is the "seal" made out of?...and maybe more importantly.....what is the "bushing" made out of? These parts will also deifne the longevity. Lastly.....for chain-driven overhead cams on engines, there is alsways a long-guide piece along the "long" lenght between sprockets....usually a metal-backed polymer. Why isn't such "guide" applied here too?

That price will buy a lot of oil and chain adjustments.

After seeing how they hold up, and when the price comes down they would help in a lot of things that use chains. I hope they're mane in the USA.

Belts, like my Harley had, are maintenance free and don't wear out sprockets. My BMW had a shaft drive and I loved it. This seems to be strictly for the racing circuits.
