asked by: a guest 2016 Trek Domane 5.2 and 2017 Trek Boone 7 disc have the same bearing set. Headset cap is FSA. Measurements are very similar to this diameters. Bottom 51x40x7 top 41x30x7. Don't have accurate tool to measure the chamfer angles. Seems like a logical fit. Thoughts?
A.
anwered by: canteau We aren't a Trek dealer so I'm not sure which headsets they use without seeing it first to compare, however this is a pretty common 1.5" lower bearing.
