Just getting into bike repair and may have goofed...
I just installed an Ultegra 6603 triple crank and bottom bracket (with one spacer on the left) on my 9-speed 105 triple setup. I realize the crankset is for a 10 speed, but was told it would work if I fiddled with it.
I adjusted the front so I have all 9 gears in the big ring (52), but there's a lot of chain rub in the three highest gears in the middle ring (39) and in the three highest gears in the granny gear (30).
This isn't too bad in actual riding, but should it be possible to adjust this setup so I have more gears. I've been going back and forth with the H and L adjuster screws and indexing, and can't seem to make it better.
I am using am SRAM 9-speed chain and rear cassette (12-23) -- would a Shimano Ultegra cassette and 9-speed chain help?
