Of course, your right about the use of cruiser frames on the first mountain bikes.
What did these riders do next? They discarded everything but the frame, for stronger, lighter and more effiencent components. The hubs, rims, brakes, and drive system, were all changed, for better stuff. The cruiser bike stuff didn't work very well. Just look at early Gary Fisher or Tom Richey bikes. These are 2 of the three people that are generaly credited with the starting of mountain biking, in Marin County Calif.
The third person started Wilderness Trail Bikes and I can't recall his name.
