Hi John, Yes, this is Trek part W524188, the 142x12 derailleur hanger used across the disc Domane, Emonda, Madone, Boone and Checkpoint frames. It's the standard-mount version, and a few frames of this era use a Shimano direct-mount hanger instead, so it's worth checking against your derailleur. Many thanks Joe W
Just received one and confirmed that is the part number
Founded in a Wisconsin barn in 1976, Trek has grown into one of the world's most recognised bicycle brands without losing the obsession that started it all: build the best bike, ride it further, share it with everyone.
Trek believes the bicycle is a simple solution to many of the world's most complicated problems. Every bike Trek builds — from the Madone race weapon to the Marlin trail bike — is made with that conviction. More riders, more often, on better bikes.
