The Skinny on Women's Bike Fit

Women tend to have more problems adapting themselves to the fit and geometry of big-brand bicycles than men do. The average bike from the bike store just doesn't feel "right" for most of us without a whole bunch of modifications.

I took an interest in bicycle frame building in the mid 90's, and began to study bike fit and geometry. I discovered many things. First, nearly all bikes are designed by men utilizing the male anatomy as the yardstick around which to create a frame's geometry and handling characteristics.

Next, I learned exactly what the differences are between women's and men's anatomy with relation to bike fit. When comparing women and men of the same height, men tend to have longer upper bodies than women, particularly, they have longer arms (by nearly 4 cm!). This means men tend to like and need more "cockpit" space than women when sitting on a bike. This is why so many bikes feel "too stretched" out for many women.

 

"Before Getting a Luna"--Cathy is way too stretched out, and her weight is too much on the back half of the bike.

"Riding Her New Luna"--A much more comfortable position, and Cathy's weight is more evenly distributed between both wheels.

 


"Women's Specific Design" bikes have been recently introduced by some of the bigger bike companies to acknowledge this difference and make an attempt to address it. Such bikes usually have shorter stems, shorter top tubes, and "comfort" saddles. While they may cause less initial discomfort, they are not necessarily set up for performance riding. Compromises are often made in frame angles on smaller frames in order to produce a bike which fits and works using the "standard" size 700c road wheels. Such modifications force many women into a less-than-ideal pedaling position and having to deal with sluggish steering. No component upgrade can alleviate this problem. Some companies have begun to utilize smaller 650c road wheels to avoid these compromises when designing smaller frames, which is a step in the right direction.

So what does this mean for women cyclists? In short, some women—the minority for sure—can do just fine on a stock bicycle frame purchased from the neighborhood bike shop. Many more can adapt themselves to these bikes if they are willing to spend some money on major component upgrades. Still others—often those who are spending the most time in the saddle —try to find a bike that fits right from the start, without any compromises in geometry, and they usually find a custom bike builder to create such a machine. This fundamental, persistent problem for women in the bike industry is why I started building custom bicycles for women only.
