Have a pair of 30 year old sun tour ratchet friction shifters still in service, on 3 x7 drivetrains..

standard freewheel hubs, because the right bearing is an inch inboard of the dropout,
has enough leverage to flex the 10mm axle in them,
, the cassette moved the bearing out to the right end of the axle.. but 7 speed cassettes are last century..

still can get parts, but may not be in every shop all the time.


I use a Phil Wood Hub,and freewheel , much stronger axle, so the bending to breaking never happens.
used the wheels on several international bike tours , camping.
