If it was me, I'd measure the chain already on this bike or go to Walmart with a tape measure and measure one there. I assume you don't have any of the paper work that came with the bike originally? What do you intend to do, Are you going to replace the chain ? You can get a kit to replace a broken chain / link, if you need to. You just punch out the rivet on one side with the tool in the kit, then pop in the connector and attach the locking clip . Remember to feed the chain through the frame at the back., before you do this.

What size of chain is on a norco 6.3 crosscountry bicycle

Its one of three sizes. The most common is 1/2 x 3/16. The best thing to do is take your chain or your bike to the nearest bike shop.

What size chain do i need for this bike

Why don't you just take off the old chain and take it with you to the bike store, since you have to return your new chain anyway and buy a new one. You don't even need to know the size, because they will match the old chain with the new chain. No guesswork required.

I need a chain for a 21speed mountain bike it is an older mongoose MGX i dont know what kind or size chain i need can you plz help me out???

Look around for a 7-speed chain. Special tools are involved for 'cutting' it to size so why not just establish a relationship with your Local Bike Shop now?

If it's really worn you'll probably also need to replace the cogs and possibly the chainrings. Old drive train parts don't mesh well with new ones.

How many links should the chain be for proper length on a 26" dual suspensin magna excitor 21 speed mountain bike

That is subject to the individual bike and the sizes of the chainrings and cassette cogs. No simple answer.

You COULD web surf for advice on "how to calculate chain size" on your own.

If you avoid cross-chaining you can run a shorter chain. I never go more than one cog beyond the cassette center opposite my chosen front chainring.

Chain Broke on a Huffy Tundra 18 speed 26" bike. I need to know the size chain to replace or the master link/chain connector to fix the chain.

if the bike has gears it does not have a master link, that is for single speed bikes only.

You will need an 8spd chain for your bike (1/2" x 3/32), these will fit any 6,7 or 8 spd bike. This requires a special tool to install ($8-$25), I would recommend taking into a bike shop and have them do it if you have no experience with this type of chain.

Side note: if you do own the tool, you can repair a broken chain for a temporary fix in the future, so may be worth buying. Check around, many bike shops offer basic repair classes and cover this.

Anybody know where i can buy a new chain for a 2000 sym husky????

There is nothing special about the chain on that motorcycle. If you don't know what size the chain is and you can't remove the chain to take it with you then ride the bike to a shop and they can measure it. Most likely it is a 520 O-ring chain. If you buy a 120 link chain the proper size you will certainly have enough links. You will take the old chain off and lay the two side by side, then cut links from the new chain so it matches.

Often there is a sticker on the bike near the swingarm that tells what size and how many links are in the chain.

Chain Size

Go to a web site like and pick the make year and model of your bike to see the part diagrams. Find the drive chain page and it will usually tell the size of the chain.
