It's not so much that my bike is shimmying. It's that I find it hard to follow the road at high speed. Like, I have to fight not to end up on the wrong side of the road. Yes, I keep my leg down, press against the top tube and try to look where I am going. It's that the feel of everything is different when descending at speed. I start shaking and that's it... I might add that this problem is mostly when I have to turn/curve right. I am much more comfortable with left hand curves.
Pretty sure that this has something to do with my astigmatism that is not corrected. I also feel awkward just turning right.
Mostly, you wouldn't this if you saw me ride; you would just think I was a very slow descender.
