I would like to ask the same question as the OP in order to recycle a found on the shelf wheel that is in really great shape (like new)..
Hub is a Shimano HF-05 (without the drumbrake threading often seen on these)
Cassette is 7-Speed Shimano
OLD is 135mm
Axle is Q/R
Desired change is to replace the current 7spd cassette with a:
New SRAM 11-34 9spd cassette
I have all the other bits on the shelf to shift it, etc.
So the question is what do I need to do to the wheel and how best to do it?
Thanks in advance for any assist
