How many teeth are on the cog (rear) and chain ring (front)?
56057
The cog has 16 teeth and the chainring has 48 teeth. Regrettably, this means the back tire has just one skid patch.

there's a 17 tooth freewheel for a 1/2 inch chain and a 17 tooth freewheel for 3/32 inch chains, typically the 1/2 inch chain is for true single speeds and BMX bikes, 3/32 inch chain is typically used for 7, 8, 9, 10, and 11 gog freewheels, multi speed bikes. A 17 tooth freewheel for a 3/32 inch chain would usually be used for multi-speed to single speed conversions. If you use a 3/32 inch chain just make sure your crankset gear and freewheel are 3/32 inch compatible.

Hi there, it has 13-15-17-20-24-29-34. It is pretty wide but it help me maintain high cadence on the large ring plus gives me the low gear for the steep climbs. I hope this helps.

the biggest is 48 teeth. But it did not work well on my bicycle. I had to reorder FD-Z 204 used one on Ebay about $20. good luck.

I don't know anything about chain guards, but I measured my bike and it's 21" from the front of the chain to the center of the rear wheel and a total of 24" from the front to back of the chain mechanism. Hope this helps you.

Number of teeth: 14, 16, 18, 20, 22, 24 and 34. The larger sprokets are riveted to the smaller ones.

Hi, that model of Trek probably was offered with more than one crank set. You need to measure the "BCD" or bolt circle diameter. That is the distance between the bolts that would hold on the largest chain ring. 104 BCD is very common.

This chain matches an 8 speed freehub or freewheel. That is, if you count the sprockets (cogs) on your rear wheel hub and you have 8 then this chain will probably work. Count the number of links in your old chain and use the same number for the new chain. If the new chain has more links you should remove some of them. Removal takes a chain tool.

If I understand the question correctly, yes. The larger numbers of teeth on the largest cog are useful for maximizing the torque you apply to the rear wheel from a given amount of crank torque, and that's useful mostly for going up hills. I installed the largest size on my road bike this spring because I had some rides scheduled in hilly terrain (particularly, the Redbud Ride). That said, a nice low "granny gear" can be pretty convenient for any sort of riding on any kind of bicycle, I think. Good luck!

mine is medium and high, but it will vary depending on the size of the front chainring and rear cog

It is a single speed bike. The front crankset has 40 teeth and is fixed to a 140 mm arm made by Proarm. The rear free wheel has 16 teeth and is made by Long Yih Industry Co. If you convert the numbers into gear inches it comes out to be 57.5. You won't break any speed records with this gear range. I ended up swapping mine out for a 170 mm crankset with a 50 tooth chain ring made by Mojo. I beat the hell out of it all winter in upstate NY and it's still running great. Not bad for $36 dollars.

I didn't get a cog with mine, I had to order and put it on myself. ChainWhips are only necessary (in my opinion) when taking off the cog. YOU WILL NEED TO BUY THE LOCK RING ALSO.

There are two versions, as shown is works with any chainring bolts because the threaded side of the set is part of the chain ring. Last years version you needed the Origin 8 single chain ring version, they are shorter and not made to hold 2 chain rings. These chain rings have tall teeth and wide narrow teeth, they are made to convert your bike to 1 by 9, 10 or 11. These are not made to work with a front derailleur.

The chain I received had 66 drive lengths. The chain model number matches the title "33 RS3 66" Part number 3624 005 0066. The textual description is a typo.

Perfectly, I had one installed with the large chainring of 46 teeth. It works without any problem if well installed at the proper height.

Howdy... all rear derailleurs need a hanger. You can buy bolt-on hangers if you don't already have one on your frame. Inespensive, but likly to break if you do a lot of rough riding. I'm not sure but I think this one will only accomodate up to about a 37 tooth chain ring. Check on Shimano's site though. My own rear cassettes only fo up to either 37 or 39 teeth.
