Suspension locks out in cold temperatures I looked around a little, but I couldn't find the answer to my question on this site.
I have a Raleigh Tekoa 1, which is an entry level XC hardtail with an SR Suntour XCM30 fork.
Recently I've noticed that biking when it's chilly out somehow locks out the suspension. It seems anything under 60 °F (16 °C) temperatures makes the fork go rigid.
My best guess is that the springs inside the fork freeze a little, causing them to become stiff. All my life I've owned bikes with spring forks, but this has never been a problem for me.
Has anyone else experienced this problem, and if so, is there an easy fix for it? This is a fairly new bike (3 months), so I doubt that I need to replace the springs.
What’s more likely is that your damper oil is thickening in the cold. If you can find a service manual for your fork, it may be possible to open it up and change the oil for a higher quality one. It’s probably not worth it though, you highly risk messing something up.
Maybe try contacting SunTour? That certainly doesn’t seem normal.
