I have an old rear wheel - I think its from a Raleigh Arena roadbike from the late 70s or early 80s. There are broken spokes that require the sprockets removed to access. I've done this plenty of times on 26" MTB type wheels.
This bike has me stuck - its a 6 speed and I cannot get the freewheel off.
Here's the first shot, after the axle and ball bearings were removed but with the lock ring and dust shield in place.
I used a "hook" tool to unscrew the lockring - it was a standard righthand thread. The dust cover responded to a screwdriver so I gently levered it out without bending it.
So my question is - do I continue using chain whips to try and unscrew each sprocket, or do I try and snag something into those two slots in the side of the bearing cup, or are those 9 tiny little slots where some special tool should engage?
