Hi folks, I am converting one of my lightweight bikes to a flatbar and I would like to use an extra SRAM X7 shifter I bought. I have a 9 speed Shimano cassette and a Shimano Ultegra rear derailleur. When I tried it, obviously there is a "ratio" problem as it took only 5 or 6 clicks to go from the smallest cog in the back to the largest. For the fun of it I hooked up my bar end shifters and it shifted smoothly to each gear. My question is - If I want to use my ultegra derailleur, must I buy another brand of 9 speed flat bar shifter? If so, what works best. How about buying a derailleur that matches the SRAM X-7? Would that be cheaper and work as well as the ultegra? I have a 12-27 Shimano rear cassette and a 50-36 Compact crankset. Obviously, I am struggling with coming up with a combination that will work well and I am open to any suggestions you all might have. Thanks.
