Can I use 11 speed Front Derailleur on 10 Speed bike
Hope someone can Help. I'm swapping all my 10 speed Ultegra Parts over to my new 2018 sirrus carbon but I need to buy a Braze on front derailleur since my clamp on won't work on this frame. My Question is I would like to use the Shimano FD 6800 Braze On 11 speed front Derailleur with the longer arm on my 10 speed set up. Will it work with my 10 speed chain and my Shimano SL-R780 Flat Bar 2X10 Shifters. Or should I Just get the 10 speed FD 6700 Braze on Front Derailleur. Thank You Roger Vista, Ca
