Wow, there is just no speed limit on this roller coaster.

Coryhibbert and especially provin1327 suffered on Ribcage so that you don’t have to. I say that with all due respect and with zero criticism. All of us have been let down by something before due to too much build up. Pay attention to their comments, so that expectations are measured; it’s a short bleepin little experience. Think of it as a sprint in track; a boulder problem in climbing; a single trip down the terrain park in skiing. That said, what an awesome trail!! And perfect to lap with easy Abajo climb.

I love Phil’s World. Hero dirt, flow, beautifully designed trails and terrain. The experience definitely worth the trip from Durango for something new. The Rib Cage is certainly a highlight but did not meet the overhyped expectations.
We hope you've been enjoying Trailforks!
