Does anyone know why this stem says it’s not compatible with other bikes yet the specs are the same as a standard stem? For purposes I would like to put on my Emonda Alr for the benefit of the stem mounted mono tt bar. by AlPha_StAte46 Bicycle Bicycling Bike Biking Cycling Trek Bicycles Trek Bikes
squirre1friend on April 21, 2026 9:33 pm Not not a standard stem. The base isn’t perpendicular to the steerer and the headset cover for the ALR isn’t the same as the SL [W577656](https://www.trekbikes.com/us/en_US/equipment/cycling-components/bike-headsets/trek-madone-slr-painted-headset-cover/p/W577656/) [compatibility chart](https://retailerassetsprd.blob.core.windows.net/techassets/RoadCockpitCompatibilityChart_Rev_8_Feb2026.pdf). Best looking at the other post where someone shares the step file for their 3d printed spacers. Hit up a friend and pay em for time+filament or outsource to one of many internet sites to get 3d printed
