RoundTail Bikes

   Stumbled across this sweet looking road bike the other day. This is called a Round Tail.

So many circles...

   The guys over at Roundtail claim that this design allows for a much smoother ride without sacrificing side-to-side (lateral) stiffness. This idea is not strictly a new one. Many companies have been changing the shape of the seat stays to absorb road vibration. Here is a Colnago with a convex seat stay:

   And no post would be complete without a Canny, so here's a Synapse with a concave seat stay:

Cannondale Synapse

Both of these are designed around the idea that the seat stay will provide some flex, allowing you to have a small suspension system of sorts.

   Roundtail has taken this idea to the extreme, but also claims that the distortion of the rear end doesn't effect the frame stiffness. Here's a good shot from the back:

Yep, it's round

   They even have a mtn bike in the works:

29er .. hardtail?

   Seems like a neat idea, but an awful lot of extra material. I am sure it will turn heads though!
