question about 8 speed gearing / sti shifters
I recently picked up a used road frame for my girlfriend. She is riding an old ross 10 speed that is really heavy so I wanted to get her something lighter so there is less *****ing. This new frame has shimano 600 components on it and an 8 speed deraileur so I guess it needs an 8 speed wheel?
My question is will the wheel from the ross 10 speed (I think there are only 5 sprockets in the freewheel) be ok in the shimano 600 8 speed derailleur?
The seller wanted an extra $100 for both STI shifters and I didn't think it was worth it so I figure I'll take the downtube shifter from the ross 10 speed and put it on there? Or would I be better off paying the 100 for the shifters? I was trying to keep this cheap
Any advice is appreciated.
