The cable pull is different because the actuation ratios of road and mtn front SIS derailers are different.
Incorrect. The road "flat bar" front derailleurs use the same cable pull as the "mountain" front derailleurs. I have two bikes in my garage- one mine, one my wife's- that use identical derailleur setups. Hers has Deore LX shifter pods, mine has R440 pods. The operation is identical.
