Sizing & Geometry
If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.

When you can only have one bike, and your mission is to ride that bike into oblivion, then this is the one. From manicured bike parks to blown out loamy berms, alpine lines to backyard trails, the Bronson is as at home in the air as it is in the dirt. For the rider with a Peter Pan disposition or who wants to get into a pan flat tabletop position, the Bronson encourages bad behavior.
