27.5 mountain bikes aren't always the fastest, but they're the funnest. The smaller 27.5 wheelsets weigh less, and less weight means more maneuverability. This makes 27.5 full suspension mountain bikes a fit for smaller riders and park rats and trail slayers who like quick, playful handling. Not sure where to start?
