those must be some tough tires. if they dont pop like a balloon and needle, i'd cry. the sides of those escaladors are sharp, i cuz up my entire leg on those last year after i feel one step. hurt like a b**ch
if you're going fast enough it's probably not that bad, if you check out the vid of the metroride the riders are BOMBING it down those things, actually pedalling down them smooth as
if they were moving, it wouldn't change anything or make it unfair. The one going up would just make the riders wheels spin faster. They would both arrive at the bottom at the same time but the rider riding the wrong way down the escalator would have a high speed rating at the wheels, but same actual speed.
