Notes on the source
SECOND-HAND NUMBERS: copied from Bike Insights (https://bikeinsights.com/bikes/63927045de2b89001c86f8bc-look-cycle-765-optimum?version=2020&build=disc), not read off the maker's own table. Source: aggregator (Bike Insights)
How I read Bike Insights' table
Bike Insights cites the maker's page: https://www.lookcycle.com/ca-en/products/bikes/road-bikes/endurance/765-optimum-disc-black-glossy-mat. The maker no longer publishes this table, so these numbers have not been checked against it; the seed stores this version as an aggregator source and caps its band (D17, D4 second amendment). Build: Disc. Bike Insights files it as Road Bike / Paved Road Bike / Endurance Road. Trail is left null: Bike Insights computes its own and the maker's is not on the page. Not checked against the maker's archived page: web.archive.org blocked this machine on 22 Oct 2026; a later pass should read the capture and upgrade this file to the maker's numbers. Generation: the 765 table Bike Insights holds for the 765 Optimum Disc (2020), the 765 Gravel (2020 to 2022, its 2020 RS version citing Look's GEOMETRY_765_GRAVEL_RS.pdf) and the 765 Optimum+ (2023), all with the same stacks and reaches; the current 765 Optimum (look-765-optimum.json) prints stacks 4 mm higher and reaches 3 to 4 mm longer. Bike Insights holds no head angle for the XL on this version, so the seed leaves that size out.
