It was you leaning...I have a dumb(?) question. I rode and finished my first double century this past weekend. During the ride, my bike started leaning to the left. It wasn't due to the wind. I tried adjusting my weight distribution, putting more weight on the right pedal then the left pedal, tried pushing the handlebars with my right arm but nothing worked. The lean was so bad that my left knee was hitting the top tube while I was pedaling. I checked the wheels to make sure they were aligned.
I had my bike professionally fitted at a LBS (BG fit). Any ideas or suggestions? Thanks in advance.
Get your blood sugar checked. I'm diabetic and I found out because buildings would oddly lean to the left sometimes (vertigo). You probably didn't eat enough.
