Nice find trailflow.
^^This product has already missed it's release deadline (july '17). Also, they raised the price from $31 to $50. At 400 grams it's not especially light either.
Nonetheless it's nice to have more competition in the rear sus road market.
I have to warn everyone though: none of these rear sus designs are damped, so they will bounce noticeably on rebound. The bobbing also robs you of power. There's no free lunch here and you'll pay the price one way or the other. Not to mention the seat rocks back and forth and does not remain level.
It's good to see more of these designs on the market. There's no doubt US roads are in increasingly poor condition. Also, Americans continue to get fatter and fatter annually.
