Why is the frame reach of the Noah (Fast) longer then the previous Noah (Fast)?

The Noah (Fast) has a steeper seat tube angle (75° in size M vs 73°) compared to the previous Noah (Fast), but the same actual top tube length. The result of this steeper seat tube angle is that the reach number will increase as a bigger part of the actual top tube length will be in front of the bottombracket and a smaller part behind the bottom bracket. When comparing the sizing of the Noah (Fast) to other bikes, use the actual top tube length as a reference number to define your frame size.
