I'm 5'8" and have 2 bikes:
aluminum Trek 1000 size 58cm
carbon Trek Madone 5.0 size 58 cm
neither is WSD. The only mod to get a good fit for me was to shorten the stem from 110 mm to 90 mm.
I have long legs and an average body. My inseam is 33/34 inches. I had a bike shop guy insist that I could only ride a WSD once. Very frustrating since I feel very comfy on my non-WSD bike.
but the geometry on every bike is different.
Oh, I ride longer rides too. I rode 80 miles today on the 1000. But I don't think that I really understand how steel would compare with aluminum and carbon. I've never ridden a steel one.
