Between two Specialized sizes

Keep both height matches while you compare saddle-height limits, standover clearance and riding position. Follow the between-bike-sizes checks before choosing.

Stack is the vertical distance from the bottom bracket to the top of the head tube; reach is the horizontal distance. Standover measures the bike, so it does not replace a published rider-inseam recommendation.
