How I read the maker's table
Rider height guide on the page: XS 162-172 cm, S 170-178, M 175-188, L 185-193, XL 193+. The other Planet X frames (EC-130, London Road, Titus Silk Road) have no geometry table on their product pages or size-guide pages (the size-chart app on those pages carries no chart for them), so they are not collected. Model year not printed (null).
