Did Shimano 105 STI levers ever come in 8 speed?
I have a bit of a frankenstein road bike that was put together by a bike shop and which I use as a commuter. I currently have the Shimano 105 brake lever/shifter combo (is that STI?), with an 8 speed cassette and a worn out crappy Shimano rear derailleur. I will be swapping this stuff onto a frame that fits me better but I was wondering if I have been shortchanged by 1 gear in the cassette this whole time. If so, when I swap stuff over, I will just spring for a new 9 speed cassette. If the 105 shifters did come in 8 speed then I will stay with the same cassette.
From the research I did on the Shimano sight, it only lists the 105 as 9 speed, and the 8 speed stuff was Sora.
Also, it looks like a 9 speed 105 derailleur will work on an 8 speed cassette. Please correct me if I am wrong.
thanks a bunch,
Please respond here since my yahoo email is on the fritz.
