Diamondback serial numbers

Is there a source somewhere that can tell me the age of a Diamondback from its serial number? The guy at my LBS says it's somewhere between 1990 and 1994, but I'd like to pin it down if I can. The number in question is: T4133774

Hi, did you ever get any more info on your Diamondback's age? I just bought an old Diamondback Axis chromoly non-suspension, I am almost certain that it is a 1991 model (because it has cup and cone bottom bracket and they went to cartridge in 1992), and my serial number starts with a U. So if they went in alphabetical order, yours may be a 1990 or 1991? If you have Shimano components on it, and if they are the original components, this page might help you a lot to date your bike: http://firstflightbikes.com/shimano.htm

I have a Diamond Back Topanga (non-suspension) that I got from a friend. According to the labels on the bike it was distributed exclusively by WSI of Camarillo CA, 93010. It is "Avenir equipped" and a "CR-MO steel fork blade." It has "4130 CR-MO Main Tubing." It is the color black and it says made in Taiwan. The Serial Number is: J90414513. What year is my Diamond Back Topanga and which model is it? Anyone?

Some companies have a date code within their serial numbers, some don't and instead have a factory and production run code. Since a brand might have used three or more different factories (especially a brand like Diamondback which isn't a manufacturer) during any one year producing it's line up tracking for recall reasons is more important then for model year. Most modern bikes are dated by the specs, usually found by old sales info. Color, parts specs, frame construction styles all are strong indicators when compared with a brochure or photos. Andy.

Diamond Back began in Camarillo, CA. It eventually was swallowed up by one of the mega companies and Diamondback became one word around '97. It's pretty easy to figure the age by the components. The Shimano crankset should have a date code and, assuming it is original, that should give you a good idea of the year. Post a pic, that can help as well. I've had a lot of DBs over the years (I live 20 minutes from Camarillo) and currently have 5. I know 2 of the '92s have serial numbers beginning with "U" and at least one '92 starts with a different letter but can't remember what it is at the moment.

You can also post in Classic and Vintage. Lots of knowledge on older bikes over there.

Diamond Back bikes started in Kent Washington in the 70's after swapping from producing bikes in Japan they started making bikes in Taiwan and China and then sold the company to Raleigh bikes I believe but that one I am not 100% on

Diamondback history from Wikipedia:

Diamondback Bicycles was founded as a BMX brand in 1977 by Western States Imports in Newbury Park, California, which sold bikes under the Centurion (bicycle) brand. Early in its history, the brand name was "Diamond Back" and over time this changed to "DiamondBack" and then to "Diamondback." Beginning in 1990, Western States Imports started selling its mountain bikes and road bicycles under the Diamondback name as well. Since 1979, many riders have successfully competed under the sponsorship of Diamondback, which began with BMX and expanded to Mountain Bikes with the creation of Diamondback Racing (DBR) in 1993.

In 1999, Diamondback Bicycles was purchased by the Derby Cycle Corporation, which also owned the Raleigh Bicycle Company, and merged Raleigh and Diamondback together. In 2001, Derby Cycle Corporation sold Raleigh and Diamondback. In August 2019 Accell Group sold Diamondback to Regent, L.P


I sold a lot of their bikes back in the "Raleigh era," and still ride one of them. I always had good responses whenever I needed to contact them about any issue.

Try placing an inquiry with the company via the "Contact Us" option on the diamondback.com web page. You might also contact Derby Cycle who still make the Euro Raleigh.
