How Difficult Is To Change Back & Front Sprockets?

My bike's chain is already slipping and the sprocket teeths on the front and the back wheel are almost flat, I want to go at it and change them myself, have lots of tools, should I try or it's simply not worth the hassle and should I just take them to a bike mechanic to do it? How much would it cost?
 
It's easy, all you need is a hammer and some bearing grease!
 
I don't know what bike it is, but in general changing the rear sprocket is easy (unless your axle nut is not rounded off.. ;))

The easiest way to remove the front sprocket is to rely on the chain and blocked rear wheel to hold it in place while you're removing the sprocket nut. If your sprocket's teeth are flattened, this may not work well. You can give it a shot anyways, and if it doesn't work, you already have an offer from reciprocity. Maybe you can talk him into doing it for $950... ;)
 
I had my chain and sprockets changed recently, the shop charged $60 for labour. For that price, I will let them do the work.

But where's the fun in that? Yes, you may spend $100 on a chain-breaker/riveter, but other than that, most people have socket sets and angle grinders, all lying next to the "flat" and "cross" screwdrivers, and you save $50-80 on a repair that you need every 2 seasons or so :cool:
 
Make sure it's in neutral and wood block your rear as stated above when taking front sprocket off.
I always take front sprocket off first, then install new front sprocket right after. I found I get a little bit of chain stretch when putting front sprocket on with new chain.... So I use the old one to torque it to spec. Then proceed to the rear....then the chain.

Easy as pie dude, did the job on Thursday.
Could have finished the job in an hour myself had I not been the typical me and continued to clean all the spaces you never get to as you're cleaning the bike (inside of the swing arm, a good rim cleaning, under the chain guard, and the front sprocket guard, etc.) A shop won't take the time to do that for you.

Spent about $50 on the chain tool from royal, and had to buy a 32mm socket for the front sprocket nut. Make sure you have a "soft" hammer to pound out the rear axle (not hard to do, you just want the right hammer)
Make sure to grind the head of the rivets off and there will be almost no pressure on the tool (see my thread on how I learned about that...)

Was a good morning out in the garage with some tools, tunes and a beer.

Learn how to do this stuff on your own, youtube the job a few times (motion pro had a really good demonstration on how to cut the chain then rivet it) and go at it... Sure, you'll spend the cost for a shop to do the job on the tool, but when you have to do this again you won't have to pay.
I enjoy getting out and working on my bikes, it's part of the game. Gives me time to inspect the bike really well, and I'm proud to say 100% of the work done to my bikes is by me.
 
Also heard you can do one foot on rear brake and a breaker bar.... have yet to try.
Anyway, subbed to this thread now. Will need this info later.
 
$850 and my girlfriend will change the chain and sprockets for ya (I was going to say "do it for ya" but the price goes up drasticly.)

Tried that once. 1st problem is that you need another person (1 for the brake and 1 to get a good go at the sprocket) as the sprocket nut will require some torque to get it off... which brings up the 2nd problem; the sprocket nut will likely require A LOT of torque to get it off. The one time I've tried it and everyone I know who tried it simply could not get enough braking power to overcome the torque required to break the nut. YRMV
