Does the gator hardshell come in schrader? If not what is going to be my best tire for rough conditions?
Schrader is a valve type and is an attribute of the tube, not the tire. That being said, I've never seen a tube that came in the sizes of these tires (700x23,25) that had a schrader valve. This is chiefly because schrader valves are larger and require a larger hole in the rim. On road bike/racing wheels, this would weaken the rim because they're already so narrow so they're not used much.
Yes they do make Schrader valve tubes for these tires, but you are simply mixing Era's. Schrader valves do not seem to hold high pressure as well as Presta valves! Also Presta valves weigh less than Schrader valves another main attribute of their dominance in high end rim technology!
