Serial numbers on a. How can you use a Redline BMX serial number to determine the model. What does “bb” stand for in my Diamondback BMX bike's serial number? Frequently Asked Questions. Where is the serial number on my bike? What is the max rider weight for Diamondback bicycles?

Serial numbers All bikes all have unique serial numbers. Most bicycles have their serial number engraved beneath their bottom bracket, but sometimes serial numbers are found in other places.

Here are some examples of where and what to look for: • The bottom bracket (where serial numbers are typically located) is circled. • A serial number on the underside of a bottom bracket.

• Another serial number beneath the bottom bracket, aligned parallel to the frame. Download Lagu M2m The Day You Went Away Mp3 Stafa Band. • Some Schwinn bicycles have the unique identifying number on their head tube (which is on the front of the bike).

• A serial number located on a rear drop out. Some BMX bikes and a few Schwinn bicycles place the serial on the rear dropout.

On older Schwinns there are numbers stamped on both the drive side and non-drive side rear dropouts; the one on the non-drive side dropout is the serial number. • Some bikes have multiple serial numbers.

When adding a bike to the Index, it's best to enter all the groups of numbers and letters separated by spaces. Hopefully you can find the serial number on the bicycle you're looking at, email if you're having trouble.

Hey guys, I have this Diamond Back frame that I'd like to know the year and model of and if it's chrome-moly or mild steel. I don't know a whole lot about DB's other than they were really cool when I was young. I was into Cook Bros then (and now). I got this DB cause it looks alot like a Cook Bros. Anyways, maybe you DB experts can help!

The finish is either chrome or nickel plated, not sure yet which. It has a 3-loop one-piece tailsection. The double front gussets are the large size.

The gussets have the diamond shape hole in them and 3 welds along the top tube and 3 along the down tube and one along the head tube, with open corners. It has an American size bottom bracket shell. There is a rounded-corner rectangular tube between the bottom bracket shell and the chainstay loop that has a hole thru the top of it.

The shape of the dropouts look alot like Cook Bros dropouts and are a little thicker than Cook's. The head tube and bottom bracket shell are straight/smooth (no outside machining like you see on Cook Bros frames). The brake bridge is a curved round tube the same diameter as the rest of the tailsection tubing. There are no chain gaurd tabs and the welds are nice, so I assume this is not a cheapo dept store model. Someone said it was made in Japan. Not sure about that but thought I would throw that in. Thanks for your help!

Also, what kinda forks are supposed to go on this and what do they look like? [ February 16, 2006, 06:46 PM: Message edited by: SoCalDesertRider ]. Cichowicz Trumpet Flow Studies Pdf Free there. Hi guys, I finally got the info to identify this frame, I think.

The dropouts are 1/8' thick, about twice as thick as the ones on my Cook Bros. The frame also has a thick 'washer' welded on top of the brake bridge where the brake caliper mounts to. The top tube length is about 18-3/8'. The welds are beautiful, tight little TIG welds, pretty close in quality to the ones on my Cook Bros. The serial number is on the inside of the left dropout and it is- '2X02xx'.

I put in the last 2 x's in place of the numbers. Someone told me if it has the washer on the brake bridge, it's a Silver Streak and the Med Pro's didn't have the washer. Is that true?

Is this frame chrome-moly, and what year is it? Is the plating chrome or nickel?

I weighed it on the mail scale and it is just a hair over 4 lbs stripped, except for the headset and bottom bracket cups that are still in it. It feels heavier than the Cook Bros, but the Cook Bros scaled out pretty close to the same, if I remember right, which surprised me. I'll weigh the Cook Bros again when I have it over here again. Thanks for ya'lls help! [ February 16, 2006, 06:44 PM: Message edited by: SoCalDesertRider ]. Look for the 'basebaball stamp' near the serial number, this will tell you if it is a Japanese made frame vs Taiwanese. Lots of good frames were made in the?????

(forgot the name of it) factory in Japan, got chrome plated and then exported out to the rest of the world to get all sorts of different brand stickers put onto them. We bought a complete 26 inch cruiser around 1981 with a baseball stamp + local brand name stickers on it, it only needed a set of Kos cruiser bars fitted on to turn it & it was ready to go.Matt has some pix of it somewhere. Unusual design & good quality bike.

This is the 26 inch cruiser frame & forks before it got all cleaned up & re assembled, Baseball stamp & all. The name of the Japanese 'baseball stamp' company is Koizumi Looks like Koizumi also made the KZ-1 Kuwahara frame as well as Diamond Backs & weird looking 26inch cruisers like our one, plus plenty of other brands at one time or another. The baseball stamp on a frame means it's GOOD quality Japanese 1980's product & I'm pretty sure Koizumi did not just limit their production of things to BMX frames either, it was/is a _big_ manufacturing facility.

Update on the forks: They have 1/2-inch dropouts, I found out when I tried to put a 3/8' axle in them. They do not say chrome-moly on them and seller said they were 'high-tensile steel'. I had to have the steer tube milled down around the race seat to fit a Tioga crown race on there. The race fits fine now. I'm thinkin' Ramon proly has it right, these are probly Viper forks. They look fine on the bike though, so as long as I can get fork washers to allow me to put a 3/8' axle in them, I will still use them on the Silver Streak frame.

MattBlack, that's a very interesting cruizer frame. Your forks almost look like Cook Bros with an extra hole in the dropouts. The tailsection on that frame looks very similar to my Silver Streak with the exception of the brake bridge. Thanks for all yall's help!
