I am in the process of getting all my spare parts together to build my fiance a road bike. I ride and race and she wants to try it. I am having trouble finding a frame for her. Any ideas on websites that sell women's specific road bike frames?

If that isn't an option, could she be ok with a men's frame? She has ridden a 54 women's frame before and it was a good fit. She definately has the leg length for a 54, but im worried about the reach in a standard frame. I know I can go with s short stem, but will it be uncomfortable for her?

Any input is appreciated. Thanks.
