What size are the chainrings? 110 mm BCD or 130 mm BCD or something else?

I just measured the center-to-center distance. It's 71,7 mm which corresponds to 122 mm BCD.

Whoops,my mistake, it is 110 mm BCD as Eugene reports. I misread my tape measure. Honestly when I got it I thought it looked kind of cheap, but it works fine. I've been quite happy with it.

I've got a few of these sets in the shop at the moment and they measure out to .118" or just shy of a true 30mm. If your scope has a 30mm tube these are a great starter set of rings.

I can not remember ,sorry.10.5x12 rings a bell but I am not sure.We had to cut,grind and repaint our brackets flat black to match our project.I recall them being good brackets .I wish I could be more help.

Something else - 584mm. Thought they would fit a neighbor's department store bike but they didn't, needed 590mm for that.

Mr. Schwager, they are 3/8 through 3/4 standard and 10mm-19mm metric. There are two adapters for a 3/8 in. drive and 1/2 drive and one spark plug socket(don't know the size). This set is well worth the money spent!!

They are 9/16". This is the standard size for all bicycles. I have mine mounted on a Shimano crankset on my Dawes road bike.

They are the standard Medium 24mm size. WARNING though. They do NOT disconnect from the elbow so you can not switch to a different size with these. It's all one piece.

If you purchase this for through us (Worldwide Cyclery) it comes uncut with a diameter of 1 1/8" and is 265mm long or 10.43" which is more than enough for just about any bike.

I actually just did a 1x10 conversion with 32 tooth up front and a 42 tooth in back. Still works flawlessly. Definitely start with a new chain though,narrow wide chain ring up front and One Up extended cog in back with the special mad 16 tooth cog that replaces your 15 and 17 tooth cog.

Diameter is 10mm. It is designed for 135mm hub spacing and single speeds typically have 120mm hub spacing (you'd need to measure your frame). Also, many recommend against using a QR on single speed bikes.

68mm is the case length, 103mm is the spindle (axle) length. you BB shell will determine your case length and threading (English is most common). Your crank arms in relation to your chainline will determine your spindle length. http://sheldonbrown.com/bbsize.html provides a table with most of the common crank sets listed. Find your crankset and under length you will find the applicable spindle length. Sugino messengers (RD 5 Bolt) and old dura ace are the only ones that run a 103 spindle length. Most of the single speeds I've seen run a 107-108. Sheldon Brown (RIP) is your "Go To" sorce for all of these sorts of questions. Good Luck!

Although I think your question isn't worded correctly (asking if they are 2.125 or 2.125) I think I understand your question. These are in fact 2.125" wide. This is a standard tire size for most of the balloon tire era (Mid 30's through mid '60's). These bicycles used a tire size of 26" diameter by 2.125" width. This tire size is also used for a lot of newer retro styled cruiser bikes. A 1.125" tire would be very narrow and not on a typical cruiser bike.

If its a standard frame it 68mm.Its a Euro frame it 71mm.And the width is determined by the crankset.If your using your old crankset( peddels and gears)Just measure the length of the old one that's your width. With crank arms removed.If your buying a new crankset use the width recomended by the manufacture.68 mm most common size for BB

i chose the 54mm and it is larger than a bike store owner suggested, but it works for me. probably a 50mm or 52mm would be ideal if they have it. warning, any time you crash, you've got a good chance to mess up your handlebars, they're not very solid. cheap brakes, and take care of your wheels, they're easy to mess up too, can get out of true very easily in any crash/accident. i like my bike, it gets me where i want to go fast, but know that it is the cheapest option for a roadbike.

You will need chainring bolts. The length depends on your current set up. You shouldn't need new bolts is you are replacing one of your other chainrings.

130mm BCD is the spacing. It did not work for me. I wound up getting a new crankset, which also required a new lower bracket with longer spindle. It all worked out in the end.

I paid the lower price (~$8) and got 4 cables, two brake and two shifter. All were plenty long for my bike. From the number of times the "size" question has been asked and the number of non-helpful answers received, I'm guessing we're never going to find out what "size" means until someone blindly buys the "size 4" for $22, without knowing what they're getting, and clues us all in. Do you want to volunteer :-)
