How I read the maker's table
Four sizes XS to LG. A women's sizing table, not the men's: its XS (500/367) and SM (520/376) are frames no other Boardman file holds, and its MD and LG print the same stack, reach, angles, top tube, head tube, chainstay and BB drop as the SM and MD of boardman-slr-2021 (SLR 8.9 Disc 2021). Wheelbase, standover, front centre and trail are not published (null); stack datum not stated (null). Frame facts from the specification list: FSA BB-CF86 pressfit bottom bracket, 27.2 mm alloy seatpost.
