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.

The Tallboy is a short-travel bike with long legs. Our perennial 29-inch bike has gone on a diet and bulked up the amount of travel to fit the kind of rider looking to maximize power hours or just ride all the hours. It’s light and efficient enough to climb with the best of them, yet punches way above its weight class as soon as the trail turns down. Excellent suspension, big wheels, thoroughly-tuned carbon layup and rock-solid reliability let you go as hard as you want.
