Firstly, a warning. This post is a product of months of obsession. As such, it is a little technical. And more than a little tedious. And of limited interest to anyone who doesn't live in a part of the world plagued with crazy, un-cyclable wind conditions. Nevertheless, crosswinds really are a big deal for some of us. And as it took me three years to stumble upon a solution, I wanted to share my recent experience.
It began when I started to ride a prototype bike for a project I'm working on with Seven Cycles. Until then I had been content to leave well enough alone. Which is to say, I had come to terms with being unable to ride my (lightweight, modern) roadbike in extremely windy conditions, when the cross-winds would get so bad they would blow me off the roads. I had mentioned this problem to several industry contacts since my move to Ireland; I have even written about it here. Over time I received a lot of advice. And while much of that advice was conflicting, two factors were mentioned again and again as potential culprits: (1) deep rims, and (2) light weight.
Since my own roadbike was not equipped with deep rim wheels (the Mavic Ksyriums I had used from 2012 onward have 22mm rims on the front, 25mm on the rear), I concluded it must be the weight - both of the wheels and the bike itself. And this seemed logical enough: a lightweight bike will get blown about the road more than a heavy bike. I would just have to live with not riding it on extremely windy days.
