Why did you clamp the stem on top of spacers? No wonder it didn't hold on to the fork...you didn't clamp it to the fork! This is user error, not a product fault.It's not too short for gravel. The reach is going to be user specific depending on the frame they have. It's up to you to choose handlebars that fit you and your setup. It might be too short for YOU, that doesn't mean it's too short for gravel.
