Hey thanks for the replys,

How did you come to the conclusion the Tern C7 frame is slightly stiffer and stronger?

Is there something documented, substantiating this comment, or is it just best guess and a lot of here say.

I would like to know how this conclusion was met.

Are the 2015 Tern Designed Flyby's less durable and Why?

Have there been a lot, or any of Failed 2014-2015 frames for Tern designed Flyby's
