I recently started changing the drivetrain on my Trail 6 (2020) and I wanted to jump to 3x11 from the 2x9 mixed Altus/Alivio it came as stock. My mistake was not paying attention to the type of pull my frame was built for, for the front derailleur: it's bottom pull.
I have all the components installed on the frame: 3x11 22-30-40 XT crankset, 22-40 11spd sprocket, 11spd XT chain with 138 links and 3x11 SLX Shifters. But the front derailleur had front pull which, sadly, cannot be used on the bike's frame. For the moment, I'm using the default 2/3x9 Altus front derailleur but, as you may assume, it's kinda bad (25% of the ratios cannot be used due to excessive chain rubbing and whatnot).
After extensive search, I've realized that there are no 3x11 front derailleurs with bottom or dual pull... only 2x11 or 3x10. Since i`m not gonna return the drivetrain (I've tested it for 2 days and it started showing signs of wear/tear, as is normal), my question is: can I reliably (or semi-reliably) use a 2x11 or 3x10 front derailleur with a 3x11 transmission? If yes, which of the two is more recommended?
