Geometry, every size, from the maker's table

The tinted row is the size drawn beside it. Press a size to draw it.

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.

The L drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm. A dashed tube is a number the maker left out (est.).

The maker's cockpit

No stock cockpit I can name, so every size is solved on a generic stem and bar unless you choose one on the sheet.

In the maker's words

Kept whole, as I read it off wilier.com.
Wilier fits its own integrated bar/stem (Filante Bar on the Filante SLR, five sizes; the page says up to 35 mm of spacers can sit under the bar and two seatposts with 15 mm or 0 mm setback are offered) or a two-piece stem and bar per build; no per-size stock sizes on the geometry table (stock fields null).
