I've seen about 2 dozen similar videos of very high quality, and still... it takes my breath away. I find myself holding my breath, even though it seems I know most of the turns, terrain, switchbacks and... those fearful steps on the Telluride side. Watching these videos over and over (I have) still makes me tense up; I can't help it.
The lead rider here appears to be flying down the trail, and on ANY bike I would be puckering and tiptoeing down that path, praying and wailing like a little girl. It's amazing to watch, even on the "smaller" bikes.
I would take a GSA on Black Bear Pass any time.
In my dreams.
Putting aside these riders' possible suicidal tendencies, I have utmost respect for their attempts.
Other than a video of 3 big adventure bikes who (wisely) chose to turn around at the beginning, I have yet to see any videos of anyone who didn't make it. Their SD cards are down the side of the mountain somewhere, unlikely to ever be found.
Wow, just wow.
