Sometimes specs don't match the actual components - because in/around '93 Schwinn was filing for bankruptcy, and had to use parts already in inventory, and that meant the same bike could have different shifters - and not match the manual.



They were still importing bikes from Giant, bought into the China Bicycle Company, and were trying to import bikes from Hungary (I believe Greensville was closed by this time). Another thought, that might be tied to the first, is that around this time, SRAM only had shifters available.



To source a bike with SRAM shifters, you ended up paying more for components from Shimano (Suntour went away around this time too), because you were not buying the complete groupo. SRAM ended up taking Shimano to court, and settled out of court some time later. My thought is that if Schwinn was looking for every way possible to save a penny, and SRAM would have cost more, it's feasible they just put the shifters you have on there now to save a buck... as you dont usually find thumbshifters on a mountain bike.



See if you can post pics. I am interested to see.



Thanks! Sometimes specs don't match the actual components - because in/around '93 Schwinn was filing for bankruptcy, and had to use parts already in inventory, and that meant the same bike could have different shifters - and not match the manual.

Or are the "thumb shifters" rotary ones on the handlebar (makes more sense).



In this case - the numbers indicated on the dial are the gears.



But again - the left being the main sprocket by the pedals, and the right being the wheel sprocket.



Each time you click to a new number - the gear will change.



Do not skip gears in this type of shifter. Let each one engage before moving to the next.



Let me know.
