These are all used frames, likely crashed and thrashed on the velodromes in Japan before I was given the opportunity to buy them... And then I use the frame like a 'daily rider' and they disintegrate beneath me....

I have purchased dozens of these keirin frames and work through them like napkins... This has been going on for years. I am now fed up with it: It is my dream to find a framebuilder who is willing to build me a lugged steel track bike with keirin geometry and aesthetics, bombproof with a threaded fork, but I haven't found that kindred soul yet... And so I keep buying these ****ed up keirin frames because I love how it feels to ride these things
