The photos of the Mitch Yeates signature Simple frame have been released.
The frame has really tiny dropouts, a smaller bottom bracket tube, a partially exposed internal headset, and weighs 4.4 pounds just to name a few things.
It's still a prototype but you can check out all the pictures on the RideUK website because they aren't even on the Simple website as of this post.
