Now this is what I call road racing...stage 17 of the Giro is up a gravel climb with sections of sustained 20%+ graded! Check out these pictures.... the top isn't even paved yet=)
This makes the climb at Oxbow Climb look like a small pimple. I read that most teams are riding cassettes with 32-34 tooth big cogs...I hope they don't finish paving the last part. Wouldn't that make it epic?
