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)	Standover (mm)
XS	520	356	70	73.5	113	425	1000	713
S	545	368	71.5	73.5	136	425	1003	745
M	570	380	71.5	73.5	165	425	1024	777
L	595	392	72.5	73.5	172	425	1028	799
XL	620	404	72.5	73.5	200	425	1049	815

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

the U.P. 2.0 and the lighter U.P.PER 2.0 share this geometry ("The UP|UPPER 2.0 is optimized for pure speed with 35-46mm tires. For wider tires ... we have the WIDE 2.0."). Not printed, so null: fork offset, trail, stock stem and bar (the bar is chosen from the OPEN BAR table, see cockpit_options). Stack datum not stated (null). The WI.DE 2.0 page notes that previous-generation OPEN riders "will usually convert to the same frame size of the U.P.|U.P.PER. 2.0 with a 10mm shorter stem to compensate for the 10mm longer effective frame reach". The page shows a geometry drawing dated 2026-05-01 (not read; the HTML table is the source). Model year: not printed (null).
