I installed a 10-speed chain yesterday to (I thought) finally get me on the road on my 105 Schwinn upgrade. The rear shifts like a dream but now I cannot get the front the shift properly. When going from small to large chainrings the chain hesitates then jumps right over the ring and lands between the ring and the guard. If I adjust the limit sufficiently to prevent this it won't go up to the large ring at all. I considered that the chainrings were too wide but the chain lands on the small ring perfectly every time.
I kept the original Suntour FD in place because it is low-normal which I thought would help ease my transition to STI. I have an FSA FD that I can install but it will require a clamp and an additional cable stop.
I'm wondering now if the cage is just too wide for the chain. Before installing the new chain and 10-speed cassette I had the shifters hooked up with the existing front and the old 8-speed cassette and chain and the front worked fine. Otherwise, what kind of adjustments can I make to the derailler? The rear of the cage is pretty much neutral...I haven't messed much with toeing it in or out.
Advice is appreciated. I'd like to actually be able to ride this thing someday!
