Question about bicycle cassette Answered
I bought an Shimano HG-50 8 speed cassette.
When fitted, I could see that it did not seem to be exactly true.
For example, if I turn it backwards with my fingers and use a spoke as a reference point, it deviates by at least 1mm
I took everything apart and tightened up the free-hub.
The free-hub run perfectly true.
It was still the same when reassembled.
So I sent off for another HG-50 ( intending to send the defective one back).
The newest HG-50 was the same.
When I try I put on another new cassette ( an HG model but very old stock) it runs true ( it is a 7 speed with a spacer).
Does anyone have any helpful input.
