I built up a Banshee Paradox with an XT M785 crank (28/40T), M780 GS rear derailleur (medium cage), M786 direct-mount front derailleur, and 11-36 cassette.
When I sized the chain, I wrapped around the largest chainring and largest cog, bypassing the rear derailleur, and added one link (two rivets).
I'm getting a lot of chain slap noise, even in the big ring, and it's driving me crazy. Every little bump you hit - clack-clack-clack-clack. At first I didn't have a chainstay protector, so I thought that was it and put on one of those neoprene lizard skins protectors. That didn't make any difference.
I picked up the bike and bounced it, and I can see that the noise is coming from the chain slapping the bottom of the front derailleur cage.
My chain shouldn't be too long based on my sizing method, and it doesn't seem like it's sagging or too long. I'm pretty certain there's nothing wrong with my FD installation, I used the clear/red tape thing that came on it to set the clearance, and it shifts just fine. Is this something you have to live with when running a 11-36 cassette? This is my first 2X10 setup, and also the first hardtail I've owned in at least 15 years. Is this a hardtail thing because there's no rear suspension smooth out the bumps?
