Specs
The hub slips over the spindle, thus the bearing sizes must match
B110 Wheel bearings D1 spindle inner 25 mm bearing journal diameter (0.9840") D2 spindle outer 15 mm bearing journal diameter (0.5906") 1200 1976-up D1 spindle inner 27 mm bearing journal diameter (1.0625") D2 spindle outer 17.5mm bearing journal diameter (0.6875")
B110 hub D1 hub inner 52 mm bore diameter (2.0470") D2 hub outer 42 mm bore diameter (1.6535") 1200 from 1976 D1 hub inner 50.3mm bore diameter (1.980") D2 hub outer 39.9mm bore diameter (1.570")
B110 Drum Hub EXTERNAL measurements
* 135 mm diameter (disc hub is more than 140mm)
* 47 mm height (disc hub is ~52 mm)
* about 82 mm overall length
The drum hub is shorter, so that when the drum is placed over it the track exactly matches the disc version.
