The geometry is a low BB height for riding stability. The sloping style is designed for use with a dropper post.
The tire clearance is up to 700 x 50c (50mm tire width) or 27.5” (650b) x 2.1(55mm tire width). *It is subject to rim width and tire nob form. It may cause the contact with the chain/seat stays. (The chart shows the exact size.)
The chain ring is double with 50t/34t. The chain stay has crushing fitting to the 43.5 chain line.
The downtube has 2 internal cable routing. The frame has no outer cable mounts but 3 different types of removable wire mounts can be installed as you like. 3 types of wire mounting parts are offered, single, double and straight ones.
With electric components you don’t have to install any mounts so very clean look can be achieved (except for brake cable on left chain stay)
