Not car related but worth a try
 

I need a 26” rear mountain bike wheel in black with .6 speed gear cassette. A new one will cost over £30 but it’s for my son’s bike and he has almost outgrown it, we plan on buying him a new bike in autumn when it’s his birthday, so not worth buying a new wheel when it’s not going to be kept and bike is probably only worth that amount second hand, can anyone help?

No longer required, now sorted
