If anything Japanese frames should be stronger. Most Japanese track frames are going to be made by Keirin approved framebuilders, which means their building techniques and brazing skill have been tested to the extreme in order to get Keirin certification. They also must use a very standardized, and also very strong, selection of tubing and building techniques in order to stay within Keirin guidelines. If you're buying a used Keirin frame, chances are, it has been crashed, or dented, but even so, it should hold up at least as well as any other bike out there.

Some of the tube sets that Ishiwata (now Kasei?) made/make are insanely lightweight and thin walled and are spec'ed for riders that weigh less than 125lbs. Sort of like the tubesets that Columbus made that were used on bikes that were desinged for things like Hour attempts or what have you - frames that were meant to be used once and then tossed. Given the pedigree of the keirin frames that turn up on this side of the pacific, I wouldn't be surprised if there are people tooting aroud on bikes that were made to be raced once or twice by riders who are techincally too heavy for the bike and quickly discarded before the bike can fail catastrophically. However, it probably has way more to do with people buying frames that are structurally "compromised."
It seems like keirin frames rarely have tubing stickers on them. It's hard to know what you're getting into; ie, most people wouldn't want a frame that's going to see street use that's made out of Ishiwata 015 any more than they'd want a frame made out of Columbus PL or KL. m. |

I think they don't have them just due to the culture.

I've seen columbus keirin stickers on a couple of frames.

As to the fragile tubing thing... not so much so. Apparently the replacement of frames was much more frequent before more stringent rules about rider contact began being enforced (prior to that there were more crashes) so riders tend to keep their frames longer, certainly more than 1-2 races. The only tubing stickers I've seen have been Tange Pro Special, Ishiwata 019, 3Rensho Super Strong, Kaisei 8630/8630R, Columbus Spirit Keirin and Columbus Genius Keirin. |

here in s/f i am aware that several people have seperated the lugs on the head tube. really aggressive skidding / torque on parts of the frame that were never meant to see forces in those directions have made frames fail. and by and large it is the japanese stuff. older italian track frames, for example, were somewhat overbuilt, if i understand a local frame builder correctly. these japanese frames, while designed to see massive wattage output on the track, were not designed with hills in mind, and all the pulling and pushing that goes on there, particuarly when slowing down. and they are decidely not overbuilt, and so it goes that they see failure more than others.

You're thinking of tandem bikes. |

Not terribly exciting. Stock Mark V with Nitto Bars, front brake, and a Belle Royal Saddle (off my old bike). I love the thing to death, even though she's destroying my knees.
