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.

Spur Gear: ID = 0.520" OD (teeth top) = 2.771" OD (teeth slot) = 2.444" Height (teeth) = 0.50" Height (bushing) = 1.30" Spiral Gear: ID = 0.506" OD (spiral top) = 1.148" Length (spiral) = 1.277" Length (bushing) = 2.135"

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.

As important as verifying that it has square bottom-bracket fitting, which it likely has, is making SURE the gear-teeth/ratios numbers match..whatever your old one is, it will create problems and more work if you try to fit one smaller or larger number of teeth, the front derailleur will not be in the right position and adjustment for a start...if your largest cog is 42T, you will be easier off with another with 42T, best to get the middle gear the same such as 34T or 32T, as well.

My chain rings are 22,32,42 and I find I can go anywhere I want with my 8-speed 32-12, which is no longer made. You may find it on eBay. By the way, if you have a rear wheel with an 8-speed cassette, you can use a 7-speed cassette with a spacer to replace the spot where first gear usually is. Sometimes the 7-speed cassette will have rivets that stick out but they can be ground flat and work fine. All my bikes have 8-speed hubs, so I can use either 8-speed or 7-speed with the spacer. I don't like 9-speed and up because of the narrower chain.

A normal gear and a higher gear. Mine is on a 20" wheel, so it is lower than a 26" or 700c. So, for me, it's a low and normal good for the city riding I do. It comes with a 19 tooth cog that can be changed to suit your needs. The chain wheel on your bike makes a difference too, on a Dahon with 52 teeth, it had a normal and high gear, but my bike has 46 teeth on the chain wheel making it lower and easier to pedal.

two short chains I believe and the fans go in reverse also. chains are three inches in length, color is similar to gunmetal, your typical chrome-ish/gunmetal color. they don't stick out. they blend in.

2 chains, as in front tires only or rears. Need to but two sets to do all four wheels.

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.

Not sure what you mean. If you have a 20" bar you have to have a chain for a 20" bar. from what I understand the drive sprocket on some saws have different tooth spacing and that would have to be matched.Hope that helped some what.

i think either version has a stated maximum of 44t chain ring. it is for triple cranks

There are two rows of teeth. The shorter are 5/8 " and the longer are 7/8 ". Hope that is helpful ;-)

No front gears. REAR: Freewheel: 7 Cogs "DNP "Slick Shift System" (14T Smallest to 28T Largest)I hope this info answers your question.

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

online it says 7- however there is both a front and rear derailleur- so 14 is a better answer.

Look on the guide bar. It will be stamped with the chain pitch and gage and length.

3.5 qtrs for the gearbox .8 qrts for the rear diff. I bought 5 qrts to have one to top off as needed
