Comparing frame sizes. As a comparison for a customer I set up a Medium 29+ Angus up with the same saddle height as a Large RUSSTi with 29er wheels to show the visual difference and saddle to handlebar height. The saddle height was 710mm in a straight line from the center of the BB to the top of the saddle.
There are a few component differences and between the 2 but it gives you a guide.
