Last week I went to colorado to do some biking. It was a blast! One of the days it rained and it got so cold it snowed. My fork, a manitou stance flow, literealy froze. I could bearly compress it. It took a couple days for it to thaw. Its been about a week now and it still isnt the same as it was. What happened to my fork? Do i need to rebuild it? Should I just trash it and buy a new one (I could use an upgrade)?
