www.diamondback.com, 2002: The name "Diamondback" has almost become synonymous with "BMX" over the years and for good reason. Diamondback's roots in BMX run as deep as any other brand's and deeper than most. You can trace them back to the very origins of the sport. If you look back to the days when the Diamondback race team "rattled the competition" and Mike Dominguez took freestyle to "new heights", it should be no surprise to see that the best BMX riders and racers in the world are still on Diamondbacks today. Like AA Pro World Champion Warwick Stevenson and X-games Park Gold Medalist Bruce Crisman and many others.
The birth of Diamond Back begins with the release of the first looptail model, encorporating a Euro bottom bracket and advertised as the 'MX'.
os-db.net: DiamondBack originated from the US in Southern California. It was a division of Western States Imports (WSI) and sister company to Centurion Bicycle Workshop who had been selling 10 speed bikes for the past ten or so years. Diamond Back was so called because Centurion thought the frame resembled two diamonds and snakes were 'kickin' The original frameset kits started to show up around the end in 1976, though manufacturing started in 1977 after early race testing and improvement recommendations by Wheels 'n Things. Their initial intention was to concentrate on getting the bike into the Californian market rather that national. When production started, early models were constructed by the same company who assembled FMF and SE using materials such as Chromoly and mild steel. The original forks were dual dropout copies of a race fork “speedo” because Sandy Finkelman liked their design and some early DiamondBack went with a similar format. Early bikes were more commonly known as just DiamondBack and not 'models' even though brochures advertise the 'very first' as MX.

It was TriMoly and can be easily identified by its Euro Bottom Bracket and square brake bridge.

os-db.net: Release of the 2nd generation 'MX' with a variety of finishes available and upgraded to the more common US bottom bracket.
dbbmx.wordpress.com: It was still TriMoly but now offered a American Bottom Bracket.

os-db.net: In late 1978 manufacturing was moved to the Koizumi factory in Japan (which was probably due to the strength of trading overseas) with the launch of the early pro models, Small, Standard and Large, all Chromoly with Steel dropouts.
1979 os-db.net: By this time the Japanese (Koizumi) had got hold of manufacturing the framesets and a variety of framesets to choose from. Chrome had also been added added to the finishes available for the 1st generation Pro and the design given an update with the introduction of the box section. Notice the TK version and gussett variation of this model. Though not originally specified, the TK was also available with a Chrome finish.

In 1979 they debuted the “Pro” an all 4130 bike.

dbbmx.wordpress.com: This is a press release from “Bicycle Motocross Action” appearing in the Feb. ’80 issue. It must therefore have been taken in late ’79. It also says the new Kit. I believe it was late ’79 for Christmas sales that Diamond Back introduced the bike kits. This would be the first ’80 model. Its kit had a SunTour stem. Suntour seat clamp, Alloy bars, Fluted alloy seat post, Kashimax MX seat, Shimano Tourney rear brake, 3 piece alloy cranks (could be SunTour maybe). The bike at first (Late 79) had no large DB seat tube decal.

1980 os-db.net: By 1980 (March) and backed up by the experience and assetts of Centurion, Diamond Back formed a race team to spearheard a National push, compiling of the already and well established DB rider David Clinton and additional names such as Harry Leary, Doug Davis, Mike Horton, Aaron Stevens, Eddy King and Pete Loncarevich under the umbrella of Sandy Finkelman.

os-db.net: It wasn't until 1981 when the more successful updated Pro range was available in Mini, Medium and Senior, or a custom Kit was available (all were full Chromoly framesets)

os-db.net: With Harry Leary on board and design/development driven by Sandy Finkelman, the Senior Pro became the testing platform and benchmark for the later released Harry Leary signature 'Turbo' in mid 1982. Leary himself provided vast input into the Turbo since it was to be his signature model. Later that year cam the tri-moly Silver Streak, similar geometry to the medium pro, but a mild steel rear triangle and slightly thicker dropouts (steel).

os-db.net: In 1982 DiamondBack had already commisioned Akisu (Taiwan) to produce a low end model, the Pro-Star and with the economic climate weakening in the US by late 1983, some model production was moved to Akisu, these being the Pro-Star replacement Viper and Pacer 500. Higher end styles such as the Formula One and 2nd generation Harry Leary continued to be manufactured in Japan, but the original "large diamond" gusset underwent a facelift (as did the Harry Leary ) and were replaced by a noticeably smaller diamond/gusset amoungst other changes.

os-db.net: DiamondBack dropped the Pacer, fearing the name was the main reason for reduced BMX sales and decided to continue with the highly successful Viper, hence the Super Viper, which was primarily a Pacer 500 frame and forks and the last of the looptail frames.

1983 os-db.net: 1983 brought the replacement for the entry level 'Pro-Star' (europe) and Moto-1 (US), the 'Viper 1st generation' and the 1st generation Turbo Lite.

os-db.net: Sandy had just finalised his previous project, the Formula One and a very questionable replacement to the Silver Streak was launched.

os-db.net: Diamond Back expanded their range somewhat, their lower end manufacturing continued to be manufactured by Akisu (Taiwan) and higher end models by Koizumi (Japan). There was also the overhauling of some existing models, noticeably the 'Harry Leary'... and who would have thought Diamond Back would drop a name due to poor sales, bye-bye 'Pacer 500'.
There were also some framesets decalled up as 'VIPER' on the chainstay, which were primarily Pacer 500 / Super Viper framesets, had an 'ABA No.1Factory Team Diamond Back' decal for the Seatstay and a 'CHROMO MAIN TUBES' decal on the seat post tube. Official literature about these model is somewhat lacking so I've used images sourced from searches.
1984 starts to see an almost waywood direction for DB.

Diamond Back has sent Mike Dominguez a letter informing the 1987 AFA Pro Ramps champ that they have terminated his sponsorship due to contract violations on his part. Among the offenses of which he was accused, Diamond Back cited Mike for wearing Haro pants in a contest, using a Hutch stem on his bike, not being a team player, and allowing his phone to remain disconnected for an extended period of time.

Diamond Back has canceled their plans for their summer freestyle tour. Thirty shows were booked, but the goal was 50, according to Woody Itson. So the company decided to drop the plans. The company's dissatisfactions with Dominguez might have had something to do with the decision.
1989 The '89 lineup of freestyle bikes remained unchanged from the '88 designs, except that the Mike Dominguez Strike Zone was renamed the Strike Zone.

December 2000, Bruce Crisman signs with Diamond Back.
Bruce: Scott Matual, the team manager gave me a call and we pretty much worked things from there. They understand the fact that I like to ride a custom bike... basically what I'm comfortable with, because I'm not just going to run anything that I don't trust my life with. They're pretty cool with that, they made me a custom frame... I run the frame and I run the pedals, seat, stuff like that.
