1. You would also need rotors- 1050 is 5 bolt rotor, 955 is 6 bolt
2. Need to validate the spacing between the rotors - the 955 has conventional calipers with 129mm center to center - the 1050 radial may be different (perhaps someone with a 1050 can measure for you.)
If different you may be able to resolve with spacers or machining of the caliper mounts
3. Both axles are 25mm but the bearing arrangement & speedo drive (none on the 1050) are different.
It may be conceivable to fit the 955 bearings, center spacer, seals, speedo key, etc in the 1050 hub & use the 955 axle, sleeve & speedo drive - the key would be in the spacer between the bearings - these are different part numbers on the 1050 vs 955.
Note that you can pull up the parts fiche for each model on BikeBandit & compare the part numbers.
