This looks weird and interesting and the price of the single speed version is actually not bad. The string is just simple dyneema cord with crimped ends, so you could probably even make them yourself from bulk and carry a dozen spares for basically no extra weight.

The prices on their different lines seem way out of whack though. Carbon and Aluminum cost basically the same? Aren't carbon bikes usually much more expensive than others?

Single speed is _way_ cheaper than the rest. Like unexpectedly so. Are they saying their adjustable gear mechanism accounts for $2000 of the price?

And Designer is in the middle?

I really don't understand the pricing scale here.
