In any event, most hybrids are a front shock away from being MTBs. Remember, generalizations always fail.
What type of hybrid did I end up with then? My frame is 19", but effective top tube is some 600mm. Bike is rigid but the fork is absurdly long due to it being corrected for suspension. Some people have 2" (street) tires on this model.
