Wrenching a Cassette
Apologies to Lewis Hine
Replace Cassette
- Â Stack sprockets and spacers back in same order (splines guide correct placement; make sure spacers are replaced correctly)
- Replace lock-ring
- Insert tool
- Tighten by hand
- Finish with crescent or torque wrench (following manufacturers recommendations)
Freewheel Removal
- Insert freewheel removal tool into freewheel, or better yet, into a vice
- Drop wheel/freewheel onto tool and engage
- Turn the tool with wrench or wheel over vice counterclockwise to break the freewheel free
- Spin the freewheel off by spinning wheel or tool
Replace Freewheel

What happened to the bloody knuckles and swearing involved in a freewheel removal?? Maybe you could do a video of stripping, regreasing and reassembling a freewheel, a true test of patience.
Keep up the good work.
If you look closely, Conor, there’s a bit of a skinned knuckle there; nothing that required hospitalization, but oaths were heard.
Ah, yes, actual freewheel disassembly–springs, tiny bearings, and pawls. Something I haven’t done in aeons.
The last freewheel I can remember rebuilding was a maillard way back in 1993. The only tools required were a hammer, a punch, a freewheel vise, some thread and a tweezers for all the tiny ball bearings. To quote Archie Bunker, “Those were the days!”
