New chain design claims higher efficiency, longer life

[Pastashop]

Is this old news?.. Does it actually work as claimed?..

good luck shifting with such a design.

Skip-tooth sprockets and skip-link chains were used on single speed and track bikes for many years. We used to have several boxes of the stuff in the back of the shop until the owner did a scrap metal sweep and got rid of it all. Cool stuff.

This might be a tweaked application of that concept but doesn’t look brand new.

Does it actually work as claimed?..

I'm not even sure what they're claiming it does in practice. From the article:

As interesting as the Dual Engagement design sounds, there are certainly a number of unanswered questions. It’s unclear at this point, for example, if New Motion Labs’ numerical claims are based on theoretical calculations or objective data. And if the numbers are based on actual test data, what were the test conditions?

My inner grump that's admittedly triggered whenever road bikes and engineering appear in the same paragraph reads this as some guys made some drawings and did some calculations, and managed to get someone to write an article about it at the bottom of the cycling news cycle.

Cycling Tips is a solid pub. Note they use words like "claim" and "The claims are certainly attention-grabbing". That's fair.

I'll check back in a year or so see where this goes.
