Need some help here......
Front chainline is 51mm or 50mm using Shimano's measurement technique. This matches my XTR derailleur specs of 50mm.
Rear chainline by all my measurements is 44????
The rear frame between the dropouts is 135mm. Divided in half is 67.5. Measured my cassette width to be 35.56mm. Divide is half = 17.78. Space between dropout and cassette is 5.842mm. Therefore 17.78 + 5.84 = 23.66. 67.5 - 23.66= 43.84mm.
This is the calculation I used to measure from the centerline to the center of a 9 speed cassette. What am I doing wrong??
