More Info:
Griffen was owned by Tony Free and was in operation for 15 years before shutting its doors in 2009. Their frames were handmade in Decatur, Texas USA and were limited in production, costing around $3500 new. The mix of materials in Griffen frames, known as Boron Carbide Metal Matrix Composite, is not melted; but rather sintered. The raw material is a fine powder squeezed together and formed into shape under extreme pressure. After the Boron Carbide was made, it had to be packed, shipped and fabricated into a bike within one week, or it became unusable. The microscopic structure created by this process is like a honey comb, which absorbs shock and vibration while maintaining a rigid structure. When the frame is finally finished, it hardens and becomes as strong as steel, provides the comfort of titanium, the stiffness of aluminum and has a fatigue life 100’s of times greater than aluminum alloys. The frames were said to be 38% stronger than aluminum alloys and 40% lighter than titanium alloys while also being stiffer than titanium alloys. "Because of the powder metallurgy process, the material has inherent microscopic pores, which is absorbent to vibration. This results in a smoother ride. Also, because we use more material by volume as our competition (our material is one half the weight of normal aluminum by volume), we achieve better comfort, lateral stiffness and power transmission all at the same time." - Griffen Bikes

How are you running a track crankset and 1/8" DA ring with a road chain? Ever have any problems with the chain falling off over fast bumps? I had problems when I ran a single outer ring on my commuter and shifted in the back, but that was ramped for shifting, not straight teeth.

The chainring is actually a 144bcd 3/32" Dura Ace ring. Not sure if i was designed specifically for track riding but I've been running the same 1x9 setup for several years now and have never dropped a chain . I considered a Paul chain keeper at first but never found a need. The 144 3/32 rings seem to be a bit hard to find though. I had to shell out some cash for the NOS 51t one im running now.

Theyre lighter and (in my opinion) look cleaner than the quick release skewers. And with the tbular wheel doesnt matter if I can get the wheel off or not im still calling for a ride if i get a flat hah

Going to step up the bmx game then when spring comes I'll buy a downgraded version of what I had before. One that I don't care about scratches or dents. I just can't get myself to ride around in spandex when it's 20° out and snowing.

i feel you. the snow is piled up here in 4-5ft in some places with no end in site. Not to mention the closest indoor skatepark is about an hour away in Rochester. Good luck on the new build, many a cool 90's/2000's frames can be had at really good prices.

I used to work for a shop in Denton, TX. One of the guys who runs it actually ended up buying the Griffen brand and assets recently. They're actually still selling some of the leftover frames and things and have even built a few bikes under the Griffen name. They aren't using the Boron Carbide mix though.

Thanks for the info! Know if they have any track frames left over?

They just might. The shop is Sprocket's in Denton. It might be worth looking into, I honestly haven't been over there in a really long time.
