Regina's New HPE Chain Claims to Need No Lubrication, Thanks to Advanced Coating

If it cuts down on lubrication hassle, that also means less maintenance needed on a long tour — a quietly welcome improvement.

What is diamond-like carbon? Just the name alone sounds impressive.

DID and RK seem to have similar coating technology too, but it was surprising that Regina went this far with it.

I feel like lubrication-free chains have existed before too, but it usually ends up needing regular maintenance anyway.

If it requires a dedicated sprocket, that means it's not just buying the chain alone — the total cost adds up.

If it's lube-free, the ta-C coating's friction coefficient must be really low — I'd like to see the actual numerical data.
