Review on ๐Ÿšฒ Shimano RM33 Freehub Body Unit: 8/9/10-Speed Performance at Its Best by Joshua Paulson

Revainrating 4 out of 5

The clutch housing is in sealed Shimano and .

Clutch body is sealed and well lubricated by Shimano. FYI - 10mm studs or external ball bearings are not included. I was able to reuse the pin and bearings from my existing clutch housing. If you buy it to build a new bike, you need to buy a bolt and bearing to use this clutch housing. I bought mine at Niagara Cycle Works. Maybe some other sellers include bolts and bearings.

Pros
  • Easy installation
Cons
  • Long delivery time
