I'm glad to see this thread here as a Calfee owner. I experienced speed wobble on my Luna for the first time Monday. As I was descending a very steep hill, my bike began oscillating more and more until it was whipping like a noodle. Really, I had plenty of time to feel the bike flex underneath me as visions of myself as road pizza danced through my head. Although my speed was only 40mph, there was no taking my hands off the bars nor putting my knees against the top tube. I felt lucky to bring the bike back under control and not crash in front of the car behind me.
Now I'd like to figure out how to prevent this from occuring again. Calfee aligned my fork before shipping me the frame and fork, so I'd like to rule out fork and frame alignment. From the thread postings, that leaves wheels, headset, and most likely me as the remaining culprits. The hill is pretty steep with a nice hairpin at the bottom, so I'm pretty gripped (pun intended)as I descend. My tense grip on the handlebars and bakes, and rigid body position most likely brought on this scare. Therefore, I can work on rider technique to reduce and prevent reoccurence, but what is the best way to confirm that wheels nor headset are contributing to the problem?
Thanks for your help,
James
