best place to buy sprockets and chain

[Bark3rd]

Well by some miracle my stock sprockets and chain still look good with at least 80 hrs on them but\have race coming up and dont want to chance it. Whats a good setup and where to buy?

I use a DID O-ring and steel sprockets 13/50. That will probably get you the longest life. If you're concerned about weight and rotational mass you might want to consider a regular chain or aluminum sprockets (although I doubt the difference is worth it considering the shorter life.)

Either way you can probably find a good deal on a chain and sprocket combo from Motosport Outlet, I know I did. Here is a link:

Thanks for the link. I ride in tight trails and have been happy with a 13/54. Do you think chains that come with the combos shown will be long enough? Looks like the biggest size rear they offer are 53's, I assume the chain will fit.

On my 13/50 I cut off 7 links from the stock chain (can't remember how many links they come with). So I would think you'd be OK with 53 or 54 on the back.

brand new a stock chain will just barely fit 13/50. after a ride or two it stretches but 7 links? wowsir.

When I said "stock chain" I was referring to a new DID O-ring, not the OEM chain. I want to say it had 120 links on it out of the box.

the best kind of chain to chain to put on a bike is a x-ring chain. the d.i.d 520xvm has the lowest rotating friction, a higher tensile strength and will outlast any o-ring chain. AFAM sprockets are also always a reliable choice

Thanks. Where can I find some info on X rings?

Thanks. Where can I find some info on X rings?

I'm totally sold on x-ring chains. Each year, I race 8-10 HS plus 10 or more all day play rides and I only need to adjust my chain about once a year. I replace the chain and both sprockets when it gets out of adjustment the second time, which is about once a year. I also take it off and clean it in kerosene several times a year to get the grit off of it, which also probably makes it last longer.

The x-ring chain has considerably less rolling friction compared to an o-ring chain. It not as frictionless as a standard chain, but you can actually spin the rear wheel with the pressure wand at the car wash (with your bike laying on its side, of course) ?

I run the DID Gold X-ring chain and either a Renthal or TAG aluminum rear sprocket and a steel front sprocket. Here's the best deal I've found on the DID x-ring chain:

Here's some more propaganda on the virtues of x-ring chains:

I ordered a "Primary Drive" brand X ring chain and sprockets from Rocky Mtn .. The entire package was $73! I cant believe how cheap. Something must be wrong, is this a cheapo brand??

[Looneytunes]

considering its nearly 1/2 the price of what I'm running, its probably worth a shot!

too bad it doesn't come in gold = no bling + more rust ?
