Geometry, every size, from the maker's table

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

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.

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.

How I read the maker's table
"The perfect all-round bike: fast on any surface, from tarmac to gravel"), four sizes S to XL. 3T prints no fork offset, trail or standover (null), and no stem or bar sizes. STACK DATUM, from the maker: the stack row is "Stack**" with the note "** Actual stack height is 15 mm higher due to Apto cable cover"; the printed stack is recorded, measured to the head tube top (stack_datum "head tube top") with the 15 mm cover on top. Model year: not printed (null). Source: html table (official 3T page "Primo 2 WPNT", geometry table in the page markup; fetched 2026-10-21, HTTP 200)
