Hi,
I am building up my first bike. It's a lot of fun and a big voyage of discovery. Latest thing that has me puzzling is this:
I bought a set of Dura Ace 7900 STI shifters from eBay. I haven't mounted/cabled them yet.
The right shifter clicks 9 times which sounds right for a ten speed,
BUT the left clicks three times which makes me think this is a shifter for a bike with 3 chainrings up front - I have only two.
So my question is: have a bought a special shifter for 3-chainring bikes or is it standard that it clicks 3 times and once I install the cables it will work for a 2-chainring front?
The FD is a Ultegra FD 6700 - compatible with DA 7900 according to the charts.
Thanks,
Pat
