I'm a typical WSD rider (5'4", LL, ST) and only one of my 5 bikes is WSD. I didn't really do anything "special" to get the non-WSD ones to fit. They got the same sort of personal tweaks (handlebar, saddle, seatpost) that my WSD bike did, and all of them use a ~100mm stem. (As an aside, my WSD bike shares the exact same measurements, right down to the angles, as one of the company's "unisex" lines. How WSD is it really? )

I guess the question is, what size and effective reach do you need to be comfortable? How much shorter does the TTT need to be? Knowing, or at least estimating that will enable you to start searching for other options from a fit perspective.

I prefer building bikes to buying stock bikes. I've developed some pretty strong fit and componenent preferences over the years, and this option allows me to address them without dealing with a whole bunch of take-off parts. Keep in mind though...it's almost always more expensive to build a bike than it is to buy a complete one. The manufacturers have more component buying power than you or I ever will. There's also the cost of assembly, depending on your mechanical level of comfort and access to specialty tools. Depending on your parts choices, it could be more cost effective to buy a stock bike and swap out a few key parts.

I don't want to dissuade you either way...just throw out some food for thought. Have fun with your hunt, and good luck!
