Compatibility with 105 shifters Can I use Deore RD-T610-SGS derailleur on my road bike with 105 shifters, it seems like cable pull isn't right. Shifters are on 2007 Specialized Roubaix compact.
Shimano 10 speed mountain rear derailleurs or 11 speed road derailleurs work with Shimano 11 speed road shifters.

Shimano 7,8,9,10 speed road and 7,8,9 speed mountain derailleurs work with Shimano 7,8,9,10 speed road shifters in terms of cable pull.
