Thanks all, the reason that I ride a MTB is that I use it for my job (security officer) and I can not afford two bikes right now (one is more than too much, but that is beyond my point). I ride over 30 - 40 miles a shift (8 hours) not constently but in 4 - 8 miles runs. With the new tires I am getting I think I can keep up with the beginners and possibly the intermediate people. Eventually I will get a road bike but until then I have to use my cannondale.

BTW I rode a S@W zap motor based bicycle and did not use the motor for the first 3 months on the job. I can say I am definitly faster on my new 30 pound cannondale vs a 75 pound motor bike. How much differnt is the weight on the mountian compared to the street bike anyway?
