For me, that's what makes it fun. But my idea of fun is my kid's idea of boring.

I can't do anything really technical with the 650b gravel bike, but I can't really do a lot of technical stuff with a well-equipped full-suspension mountain bike. In general, it is much more efficient to ride a gravel bike. If drop bars and no suspension aren't deal-breakers, go for it.

My legs are too short for a dropper post.
