Thank you for the offer -- I do need a threadless stem for this bike, though, and I think I will be okay with the 7cm stem and the Eva handlebars. That should buy me about another 3 cm in reach, which right now feels like what I need.

But I really can't use a Brooks on this bike, I don't think. We just had a little breakthrough -- we put a series of men's saddles on it, and with every one of them, we were able to easily get the saddle far back enough to put my knee in the proper position. And I can ride a men's saddle, I think, if it is the right one, because I have narrow sit bones ... lately I have been feeling like my Butterfly is too wide and squishy. The best was my husband's Selle Italia Flite Trans Am, but he says I can't have it because he is a very bad husband. I also liked a Selle Royal Sport okay in terms of length and width, but it was way too squishy. Still, I think I can find something that will work. Thank you for the encouragement!
