Yes, the Rocket and FasTT used the same beam. It was a straight beam that came in either carbon (black) or aluminum (silver).
The difference between the two bikes is the rear triangle (Rocket had a small triangle, FasTT had a solid chainstay).
The problem beams were apparently a batch of carbon beams for the Rocket / FasTT. Aluminum beams, and beams for other models (beams with a curve in them) did not have these issues.
I must have been lucky with a good beam, because if anyone should have damaged a beam, it should've been me. Top end of their weight rating (sometimes over, especially with behind the seat bottles), and I rode hard. But no problems.
Only qualms were it was so adjustable, it took a bit to dial in a fit. And it was hard to find a fitter who understood how to adjust it.
