Here is some info about the forth version of a classic frame from Fly Bikes; The Pantera! They have added all the new features to have the best looking and strongest Pantera ever made. Here are the changes from the last model:
-INTEGRATED DROPOUTS. Like on all our new 2010 frames, it comes with the integrated dropouts. These have a different design

than the Tierra that we showed you days ago. Still small but a bit bigger than the Tierra ones and with removable chain tensioners.
-TAPED TOP AND DOWN TUBES. With more diameter where you need it. On the head tube junction. And less where you don’t need it, on the bb and seat tube. Also seat tube is slightly taped to save some weight.
-HORIZONTAL CUT SEAT CLAMP. Just tight the bolt a bit and it’s on place. No more broken bolts.

-SBS BRAKE MOUNTS. The new brake system to put your brakes and remove them in seconds…
-NEW SEATSTAYS BRIDGE. New invest casting bridge with a personal shape.
