OK, I don't normally enter competitions on BMX forums, but this year I did something unusual for me and actually built up a bike.  This bike is pretty special to me as it is intended to be a replica of the bike I raced in 1980 - 1981 and had probably the best years of my BMX life.


The bike is a Team Quicksilver and it's configuration is as close as I can get to my race bike in mid 1981.  My Avatar photo is me racing that bike at Cardiff, NSW in the Winter Open.


Details of the bike:


  • Team Quicksilver Frame - rechromed by previous owner
  • Tange TRX Forks - rechromed by previous owner
  • Shimano DX Hubs with Aray 7C rims.  Wheels appear to be suvivors - bought off eBay was going to relace, but ended up not bothering.
  • Mongoose OPC.  Survivor, used on the original bike and kept in my "parts bin" from 1983.
  • Addicks Graffite 44T Chainwheel and Red spider.  Rusty Bolts.  Again, original parts from my parts bin.
  • KKT Red Pedals - from the original bike.
  • Red-Line V Bars (not repro)
  • Oakley 0.5 Grips (NOS)
  • Tuff Neck
  • Suntour Headset Lock Nut (NOS from my parts bin)
  • Dia-Compe pre-bent levers  (NOS from my parts bin)
  • Tourney Front Brake (parts bin)
  • Diacompe MX-2 Rear Brake (parts bin)
  • Finned Kool Pad brake pads (parts bin)
  • Original Front Brake Cable
  • Repro Rear Brake Cable
  • Addicks Seat Clamp (NOS from my parts bin)
  • Fluted Alloy Seat Post (repro, I think)
  • Kashimax Seat (NOS) (should be an Elina, but haven't found one yet)
  • Haro Number plate - actual original number plate from the race bike
  • New Chain
  • Repro Quicksilver Frame Pad
  • Original IRC 20 x 2.125 Front Tire
  • Repro Competition 3 20 x 1.75 Rear Tire
  • NOS BB and Head Set Bearings.

So that's it.  It's not 100% correct as a replica, but it's so close that it doesn't matter to me.

That article came out in the Dec'83 issue of BMXAction - I was 15/16 (same age as these young local east coast entrepreneurs) and was awed by the fact these kids started they're own line,I was like "no shit, that's so badass". Back then it was a pretty big deal (at least to me).
As you can see the only magazine reference model they ever got shows a Looptail frame, the story goes, they had an initial company mock up 3, or so, prototypes, but the deal with that company fell thru, which is when Coast Wheels (CW) was commissioned to produce 1 run of 50 framesets.They sold thru to '85, when Peter Dale left for college.
Frames are roughly 19" top tube (though it's beeen said some may have slightly longer lengths, most I've encountered along with mine measure 19). So it's basically a pro sized model.
As you can imagine they are extremely rare and of the 53 or so ever produced, less then 10 are know to be in collector hands.

Tried to build with slight team rider influence and then some. Most won't know or ever heard of these framesets, but I hope you can enjoy it just the same....

Breakdown :
* all finishes and decals are original unless noted otherwise

1983 DALE RACING pro 19" serial DR 1008 (production started 1001)
1983 DALE RACING fork
1983 Race Inc. (rare) RH-7MC "Holeshot) chromoly race bars
OG Oakley B-1B grips (survivor)
Early DK xl (drilled out bitd pulled off a personal acquisition)
Early DK sharp edges head lock collar and 1.5" stiffener
Tange MX-5 alloy speedline headset (stripped survivor, left unpolished)
DC tech III lever (came on the same survivor as the stem)
DC 890 with quick release mod
Kool Stop international brake pads (grey for alloy rims)
Terrycable brake cable
Terrycable (rare) 180mm "Power Cranks"
Modified machined solid disc (used a later Haro disc for desired look)
Alloy chainring bolts
Takagi track 44t
Izumi blue and nickel (survivor)
Shimano DX
Early spare edge DK round seat clamp
Race Inc. chromoly seatpost (thin walled w/proper max height crease)
CyclePro ShotGun II speedline saddle

Wheel set :
1st gen DK (rare) hubs
Asahi double butted stainless steel spokes
OG alloy nipples
UKAI silver speedline rims
Old logo Cheng Shin comp III tires and tubes (both skinnies)

California Lite pad set
70s chrome plated steel axle caps
Zeronine plate
Chrome plated crank dust caps


Subtle details ....
Survivor OG drilled out early DK (key way slot) and DC lever
Pete's Precision Products sealed BB (no cups, press-in bearings) w/rare 180 Terry Cable Power cranks

1981 JMC Black Shadow

This is a copy of one of my race bikes BITD. I was sponsored by a local BMX Distributor and the owner got me a factory co-sponsor with Bear Development. I was his walking billboard and he wanted me to promote parts that he sold from his company. I raced 20” and Cruiser class. My 20” was a 1981 Black Shadow. My original race bike was promoted to be a light race bike for a 160lb rider so I had drilled out cranks, rims and seat. I didn't drill out any parts on this bike.

Forks: JMC (repowdered with replacement decals)
Bars: JMC Pro
Headset: Chris King

I bought this bike earlier this year off ebay from the original owner who said he built this bike with his dad circa 1982. The bike was missing the wheels, tires, chain, seat, and seat post. The original bike was done in blue and gold, so I changed out the gold pedals, seat clamp, power disk, and chainwheel for black or blue to better match the frame and z-rims. I decided to use the graphite z-rims, bullseye hubs, UNI seat, and Oakley 3 grips because those were the parts I had on a PK Ripper I used to own as a kid. I'm real happy with how this bike turned out, but I've recently replaced the UNI seat with a Kashimax Aero because I'm just to heavy to ride it with the UNI.

Parts Breakdown:

Frame and Fork- SE Racing w/Original paint and stickers (drive side landing gear stickers were missing and have been replaced)

Drivetrain- Takagi Cro-MO 180 x 24 cranks with Tuff Neck power disc and Suntour 44 chain wheel

Chain- Uzumi

Pedals- Shimano DX

Stem- Cycle Pro

Bars- GT Expert

Grips- Oakley 3

Pads- California Lite (SER pad in first picture is a possible reproduction)

Wheels- 5/81 dated first generation graphite z-rims with Bullseye hubs

Tires- reproduction/re-issue Tioga Comp III yellow label fat and skinny

Seat- UNI Hammerhead

Seat Clamp- Dia Compe

Brakes- Dia Compe MX 1000 w/tech 3 lever

Headset and Bottom Bracket- Tange

1982 SE Racing PK Ripper

** This bike will not be on the ballot, as I am not eligible for voting as the host of the event.  However, as with the other bike, I just want to include it as a testament to 2014.  It was a pretty good year for me as far as bikes go.




1985 GJS Big Tube

Entirely Original Finish Throughout


Core elements

  • Frame: Big Tube by GJS
  • Fork: Big Tube by GJS



  • Handlebars: SE Powerwing Tall
  • Stem: Pro Neck II
  • Grips:  Uni Grenade (From the mid 80's!)
  • Headset:  beartrap
  • Headset/Stem Lock:  Suntour  (I've had this particular piece since I was a kid, lot of fun to put it on a bike again)



  • Cranks:  Sugino 180
  • Bottom Bracket:  not sure
  • Sprocket:  44 t Sugino
  • Spider/Disc: Sugino
  • Pedals: Shimano DX
  • Chain: Izumi



  • Brake: Dia-Compe MX 901
  • Lever: tech 4
  • Brake Pads  kool stop
  • Cable:  no name



  • Rims:  Araya 7X satin finish
  • Hubs:  Sunshine
  • Cog/Freewheel:  Shimano 16
  • Tires:  Comp III


The motivation:  I love GJS. I really hold the brand in high regard.  I also really like Jeff Utterback.  He's super humble and just a cool guy.  I also like Long Beach / Signal Hill BMX history.  I relish it.  So GJS really interests me in general.


This bike was featured this past March in our BMX Society Bike Check series.  I will be brief here since it's all been explained before.  Basically... i like to "get into character" when I put a project together.  I like to imagine myself as a kid, back in the era of the bike and try to do something that reasonably approximates what I or another youth of the era would have actually done.  Since these frames are partially hi-ten, they were affordable. They were not the most expensive thing available, and for that reason I think that component choice would have been likely to reflect that same affordable sensibility.  Extremely sick design, but I think of these bikes as a bitchin' work truck, not an exotic sports car.  I tried to build it accordingly.


I really enjoyed this project.

Ok, so this one comes with some skepticism. 1981 SE CROMO Loop Quad. I bought this outta France this year as OG finish. I have had a few SE nuts tell me the loop quad was never produced in chrome??? I can assure you this has not been plated using modern processes. This chrome job was done BITD...probably overseas? I say this because I can not get a reliable source to confirm, nor deny what I have here to show y'all. Like I said I bought it from a dude in France, and located  NOS decals and sweet pads complete this beauty.

1980 Quadangle (STR1)


Even though I built this as a replica of Stu's early Se race bike, many here feel that there wer not any production quadangles until 1980. This one is definitely mild steel and OG finish found a few years ago by Darren Chan. I let Larock lease it (LOL) but got it back to finally build it. All og finishes.



FRAME: 1979 or 1980 mild steel Se racing Str1

FORKS: 1979 Race Inc/Cycle Pro fork


STEM: Unstamped Tuff Neck

GRIPS: Oakley II

PADS: OG canvas Se from closed BMX shop out of Wisconsin (MR BMX)

WHEELS: Araya 7b with dated 1978 79 Shimano hubs from Mark OG spokes from closed bike shop inventory

TIRES: Black wall Mitsubishi Competition II 2.125 and 1.75

SEAT POST: OG Laguna solid


SEAT: Early Kashimax

BRAKES: Shimano Tourney with Mathauser shoes

CRANKS: Early Takagi MX with Takagi spider and chainring


LEVER: 1978 Honda dirtbike hand bent like Stu did it

LEVER COVER: 1978 Honda dust cover (MOTO style like we used to run back then)


NUMBER PLATE: Hand cut like Bob Haro originally did for Stu by Michael Gamsetter (This is a lost art like the Pickle used to do BITD)
