I have recently changed my cassette from a 11-32 to a 11-25 (11 speed). To make the change possible, I have reduced my chain size to 106 links (53 inches) by the largest cog, largest chain ring method. For further information, my crankset is a 52-36 teeth.
When I installed my RD-6800 (SS), I noticed that even by removing the B-screw, the derailleur is never too close to the largest sprocket (largest sprocket, smallest chain ring configuration). How is that possible?
I thought that maybe I screwed up the chain sizing, but I have just recalculated using the equation and the recommended chain length is 53 inches:
L = 2*(16.125) + (52.0/4 + 25.0/4 + 1) = 52.5"
Is it maybe due to the bike or hanger design?
