Emily,
Terry is adressing the issue of small hands reaching the brakes. Short reach handlebars are shorter between the hoods and the drops of the handlebar, not the width of the bar. It affects the placement of the hoods so you don't reach so far. Does that make sense?

The Deda 4 girls are about an inch shorter in length than the Terry's and smaller in diameter for smaller hands.

It's hard to explain because it seems that if your tt length is correct it shouldn't matter about the handlebar length but it does. The short reach handlebars compensate for the shorter arms that small riders have.

Before I got the new handlebars I felt uncomfortable sprinting. After I got them I started sprinting without even thinking about it. I think they give me a more natural placement of my hands so I'm more comfortable out of the saddle. And I am more comfortable riding in the drops.

My shop ordered them for me. Deda is listed under another company name and was hard to find. Salsa also makes them. My shop just preferred the Deda brand over Salsa.

Hope this helps.
