I want to yank the Suntour X-Press shifters off my bike and replace them with SRAM or Shimano shifters. Not sure sure what will work with the XCE rear and X-1 front derailleurs. The rear cluster is Suntour and the crankset is Suntour X-1. Bike is an unknown year Fisher Hoo-Koo-E-Koo that I'm guessing this group wasn't original on. The shifters work, but I was never a fan of them. The bike was given to me 6 years ago, and I never look a gift horse in the mouth. Its a decent ride and I'd like to make it better.
