I sold my beautiful Masi Gran Corsa (late 70's early 80's steel lugged frame....) and got Bent. The arthritis in my hands makes any upright an exercise in pain management. I ride pain free on my Giro 700 (formerly a Giro 26). Do I wish it was lighter? Yeah, but I cannot afford a TiAero or a CA2, plus this is one of the few bents that can take 559, 650c, or 700c wheelsets without any changes, provided they are disk brake hubs. I can run fenders if I wish, I can run up to 1.75 fat tires for sure, and maybe up to 2.0's even. On the 700c wheels I can run x25's and still have clearance. The only change I can think of making now, would be to consider swapping my 30T granny for a 28T, but where I ride, it really isn't necessary.
