Notes on the source
SECOND-HAND NUMBERS: copied from Bike Insights (https://bikeinsights.com/bikes/63d9fd68af4be0001f19ad42-look-cycle-t20?version=2020&build=base), 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/my-en/products/bikes/track-bikes/t20/t20-speed-version-frameset. 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: Base. Bike Insights files it as Road Bike / Paved Road Bike / Track/Fixed-gear. Where it measures differently: top_tube_effective is its effective_top_tube_length_center_center. 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. Look's T20 track frame (speed version); Bike Insights' 2022 895 Vitesse entry holds the same stacks and reaches (its sizes listed three times over).
