New type of shifting. Variation on derailleurs.
Interesting take on how to manage chain tension and use a traditional low friction, simple derailleur shift. Seems to be a good solution without the weight and complexity of a gearbox.
Wonder if it will take off.

Re: New type of shifter. Variation on derailleurs.
My thoughts were initially that somebody got bored with playing snakes and ladders with that chain routing!
But after watching the video:
* Needs a clutch on the tensioner. Slow-mo sequences show massive chain slap.
* Places limits on suspension pivot placements, but may have timed it right with the trend to high pivot designs for some uses being seen currently.
* Getting the rear derailleur out of the way of rock and log strike, and of catching the derailleur when exiting off the left side of North Shore features (risks exaggerated by the huge derailleur cages mandated by dinner-plate-sized 1x12 cassettes) could see it gain some traction here in Sydney as well as his Canadian home territory.
I can't see mass market adoption, but there could definitely be a niche application.
