Sorry about the questions tonight, but doing it first thing in the morning so I can go riding.

Going to change the rear sprocket, do I have to remove the hub or is there an easier way. Any hints or tips.

Also my chain broke and Im changing the front sprocket, Everyone says to lock the front break and put it in gear. With no chain how hard is it going to be to take off the front sprocket??

 

why not change all the other stuff put the chain on and then use it to replace the front sprocket.
