Geometry, every size, from the maker's table

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

Size	Stack (mm)	Reach (mm)	Head angle (deg)	Seat angle (deg)	Head tube (mm)	Chainstay (mm)	Wheelbase (mm)
XS	510	358	71	72.5	117	408	971
S	532	369	71	72.5	143	408	991
M	554	380	72.7	72.5	159	408	983
L	574	388	72.7	72.5	179	408	997
XL	594	396	72.7	72.5	203	408	1013

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

The M 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

"Designed for road tires up to 35 mm WAM"), one table for both, five sizes XS to XL. 3T prints no fork offset, trail or standover (null), and no stem or bar sizes. MAKER FORMATTING, kept: the XS BB drop is printed "77,5" with a decimal comma, recorded as 77.5. The row labels read "Headtube lenght", "Toptube lenght", "Seattube lenght" (spelling as printed). Front center falls from S (596) to M (587) and wheelbase from 991 to 983, as printed (the head angle steepens from 71.0 to 72.7). Model year: not printed (null).
