i new at this, so i'm not sure what i have to take off to put on a new tire. I know that i need to take the tire off, but do i need to take off the disc brakes, bearings, and sprockets? or can i just leave everything on to get the tire changed?

 

i'm guessing u know how to take the wheel off rite??..well u need to take off the sprocket..it just pops off when u pull on it..make sure u don't loose any of the rubber bushing that's underneath the sprocket

 

You can leave the rotor and bearings on. If you've never changed the tire then I suggest you get with someone that's got experience for the first time. It'll save you lots of cussing and scratches.
