Is it not recommended to go faster than this? On a nice flat road I could use one more gear slightly taller than my 3 and 8 combo. I'll have to count the teeth when I get home.

I got this bike used, but I think it's around a 2005-06ish. It's Jeep brand frame and handlebar, but the front fork and stem seem to be different, as they are very beefy, stiff, and light. The whole bike is incredibly light for a mountain bike. I have street tires on it as well. My intention with it is to make it a mean street bike. Lighten it up more with some carbon pieces, maybe put a slightly thinner tire on it, and possibly some aero bars for the downhill runs.
