New Chain, KMC X11SL jumping off lower pulley
Hello, I have no idea what I screwed up.
Trying to learn and be my own mechanic, I replaced the old Dura Ace chain on my Sram Red22 groupset. I bought the groupset used and it came with the DA chain. I liked the gold color and heard that the KMC chain (X11SL) lasted longer so I went with that.
I did the big/big measurement with out connecting to the RD and added 1.5 links.
Installed it, and test shifted, I have no problem with all 11 gears in the rear when on the small ring. When I shifted to the big ring, any of the gear other then the smallest 3 in the rear, the chain would jump off the lower pulley (the one closer to the ground). I then double check the new and old chain and they have the same amount of links(54).
Anyone able to tell me what could cause this?
The new KMC X11SL came with a very stick wax like coasting, after this happen, I added some dry lube hoping it would make a difference, it didn't...
Btw, if it makes a difference, it jumps to the outside.
