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.

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.

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

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.

Depends on the number of teeth. This was taken straight from ACS' website: Available sizes: Smaller M30 Threads: 13T, 14T, 15T Standard Threads: 16T, 17T, 18T, 19T, 20T, 22T Hope this helps.

the rear wheel, chain, and crank is on the frame. easy to finish it off. took me about 20 minutes. attach handlebar to neck, insert neck into front fork, put seat and seat post into frame, put on front wheel, put on peddles...DONE!!!

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

If your sprocket and chain ring are 3/32 then yes you match chain and tooth size.

The choices are up to 32 teeth cog, higher number teeth gives you more torque going uphill but of course you become slower but pedaling will be much easier. Your strength helps a lot too.

028342's answer is correct. however they come up with 18 speed because this can work on a 6 speed rear. the widths of each gear between 6/7/8 are roughly the same but 6 speeds for the most part went out of production years ago so they stopped marketing chains for them. Bikes are usually marketed for how many total gears they have ( the number of chainrings in the front x the number of gears in the rear). but chains are made for specifically for the rear gearing due to difference in width between each cog and width of the cogs teeth (more gears=smaller width) so they are marketed for the rear gearing and include the total gears as an added discriptor. 028342's answer is correct. however they come up with 18 speed because this can work on a 6 speed rear. the widths of each gear between 6/7/8 are roughly the same but 6 speeds for the most part went out of production years ago so they stopped marketing chains for them.

It is a pair. One in the left hand and another on in the right hand both fixed in the handlebar. The left hand controls the crankset ( 3 gears ) attached to the pedal. The right hand controls the cassette, attached to rear wheel ( 9 gears ). This system is said to have 27 speeds ( 3 x 9 = 27 possible combinations )

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.

The question is relative... It fits Shimano Bottom Brackets. Do you have a Shimano Bottom Bracket? How many 'teeth' do you need? If you look at the photo enlarged, you should be able to count 10 'teeth'... But since it is a two dimensional photo... you only have half the story.

Yes, this is the three ring chain...30 teeth, 42 teeth, 52 teeth. I just put it on my Fuji Newest 3.0 this weekend. It works great. This includes cranks. You should, if you are going to the trouble of changing cranks and chain rings, change your bottom bracket as well.

The left is friction so it will do 2 or 3 chainrings on crank - versatile. Right is 7 spds, but I've used it w/ an 8 spd, you just miss a cog at top or bottom. Fyi: 6,7 & 8 speed use same basic chain & gear spacing, so interchangeability is nice.
