I went for a short ride today on washed out power lines and 4wheeler trails. I did notice an improvement in traction. I slipped going uphill 3/4 times, but this was on pretty rocky terrain. Since I'm new to riding, I only can compare the Specialized "the captain" to my original tire, but I have to say there is a huge difference in traction. Now I just have to figure out why my rear disc is squeeling.
