IS there a mtb w/o suspension?

A MTB w/o suspension is called 'fully rigid' or simply 'rigid'. Many exist such as the Surly Karate Monkey (I have one and its the funnest bike ever). The Specialized Hard rock used to be rigid; might find a model there. Raleigh also has rigid bikes I believe. Visit a few bike shops and you will be set up in no time....
