| reason | Canyon publishes no defensible conventional equivalence for its letter sizes. Canyon publishes rider-height ranges and geometry only, and explicitly declines any centimetre equivalence. Its road sizing guide says 'Don't get hung up on traditional S,M, and L sizing. The equivalent of a medium on one company's bike could be a small or a large on another', and its sizing guide says 'No need to decode old-school geometry charts or debate whether you need a 54 or a 56 cm frame.' The Ultimate geometry sheet's size columns are 2XS…2XL with a body-height row and a seat-tube row (434-614 mm) and no centimetre size name anywhere. Canyon's own size chart controller is disallowed by its robots.txt and is not fetched. Mapping Canyon would mean overruling the manufacturer's published position with a guess. |
