Looks very clean method for adjusting things, never seen before and pinched this from retro bike forum.

Very little throw.

Gut reaction is it might be difficult to line up the wheel with two independent eccentrics.

Cost V slotted?

Can i hear a creak ? – plus the same can be achieved much neater with an eccentric bb.

I like paragon style sliders

Cost, fragility, complexity etc etc. Alignment should be okay with the graduations

Just thought they looked pretty neat.

Also,you’ve got to align the caliper as the hub moves somehow. I like rockers (blackcat/salsa)

It’s for a belt drive, so it doesn’t need much. The belt will break long before there’s enough wear to create a problem with adjustment range.

Why is’nt this method used more?

Hopefully they’ve done the maths right for the stay length/ratio/limited belt lengths.
Been there,sweated that (it worked btw)

I’m assuming that works automatically, but it’s another bit which doesn’t seem simple.

It’s easy enough, just align the wheel in the frame by sighting from behind when making big adjustments, then smaller ones as the chain wears are just a 1/4 turn on each screw.
