I will readily admit as a recreational keeper bike, a rigid frame MTB or a hybrid can be a compelling value. In our keeper fleet, my wife has a Giant Cypress (hybrid) and we have two Trek 950s (rigid frame MTBs). Great bikes for what they are. So I frequently recommend them to friends looking for a recreational bike, lots of functionality for a very low price. And the occasional rider often prefers the trigger or twist grip shifter over a DT or STI shifter. I have never been able to convert my wife to STI.
