Recommendation for a FD for 2x9
Hi
I need advice regarding a 2x9 setup with brifters and a 36-22 MTB crankset. Motivation: 36-12 will give 20mph at the 90 rpm cadence with a 40-559 tire, 36-11 will give 22 mph -- it is enough for this bike. Most of the time it will be in the 36t chainring with 22t rarely used as a bailout.
Will a regular road double FD (specced for 46t-52t big chainring) work with a 36-22 crankset?
Some people say that Shimano mountain FD can be made to work with the road shifters despite the different cable pull - has anyone tried this? And what kind of shifters - old Sora 3500 or new Sora 3000 (which has a new cable pull for double)?
I know that there are solutions involving a bar end shifter or a thumb shifter, ideally I would run brifters as they are.
