I have a crazy question that I can't find answered anywhere. What does the "28T" refer to in Bianchi's so-named models? My guess is 28" (700c) Tubular rims. I've had my Tipo Corsa 28T (originally had tubulars) since I built it in 1984 and never really knew. (We didn't sell Bianchi - I had a friendly other dealer order it for me - so I wasn't that familiar with their designations).
Thanks!
