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.

Seriously. The Megatower’s big wheels, long-travel and tough carbon fiber chassis delivers the high-speed security traits of a race bike. Yet the relatively steep seat angle and size-specific geo maintain the Mega’s mega pedaling ability, elevating its reputation as the perfect choice for big gravity rides, park laps and enduro racing.
