Facebook Twitter LinkedIn Pinterest Bluesky Threads I have a 2023 Trek Madone SLR in Deep Smoke and noticed this discoloration on the seat stay. It’s smooth to the touch (second pic), but looks like the paint is fading or is the carbon stressing? Has anyone seen this before? by coltonian98 Bicycle Bicycling Bike Biking Cycling Trek Bicycles Trek Bikes
