Whats up fellas :thumbsup:

Going through the paces spec'ing a long range commuter ebike and I am caught on the FDerailleur. I Want to run 36t-52t front chainrings, but don't really feel like spending extra $ to get a flat bar road front shifter or mount a downtube shifter on my handlebars.

Thumbies from Paul Component Engineering

Any ideas on how to get a mtb shifter to work with a road front derailleur?
Or how to get an MTB FDerailleur to work on a 52t chainring?
Is a '9speed' 2-speed front Tiagra shifter okay with a 10 speed drivetrain?

I will be running a MTB cassette and staying off the granny gears to keep my chainline as tight as possible, so 10 speed is ideal. But 9 speed is a possibility.

Any other ideas or criticisms on any of my ramblings?
Should I just break the bread, shut up and report back when its done?

An older front derailleur will cover that spread.
Look for a M900/901 (XTR) or M730 series (XT).

Thanks bro, looks promising, will watch ebay and try my local bike 'PickandPull'.

All these darn road FDerailleurs are bottom pull, which is not gonna work for a mid-drive electric motor.
