I'm now totally frustrated trying to assemble parts around this Campy 10 speed to get easier gear ratios than just 34 in front and 29 in back. I only found one place NOT in Europe that has a Chorus 10 speed cassette with a 30. And they had one. Screw it. Shimano and SRAM are so much easier to build out and find parts for. I'm just gonna use the SRAM shifters and derailleurs and cassette (with a 32) and brakes I have on another bike, buy a new 6-30 FSA crank and BB, and use those. Easy. Jon more proprietary Campy. DONE. I'm gonna start another thread I'm so frustrated!
