I'm a wannabee tourer, I got a decent bike, have done some hundreads killometers last two years but less then I want to. Anyway, my tourerbike is a Crescent 707, a rather good bike. Alu and a bit flexy and heavy as hell but it works. The only thing that really bathers me is that some genious at Crescent inc put flatbars on the bike! I've equiped it with barends and time trial-bars but that doesn't work very well for touring. Now I wonder if I could install a dropbar but keep the pneumatic brakes? I suppose I could change it for wire-disc brakes but that's a bit to expensive I suppose.
Maybe should have post this thread in bicykle mechanics but I think you were more experienced.
