Project Nippon

Yes, NJS parts would be the most ideal, I just heard that the keirin frames aren't particularly strong, so wanted some info on stronger Japanese frames, something that can handle some uneven roads every so often!

With a name like Nippon, sounds like the guy with the answers I need... maybe

he doesn't have the answers. i promise.
keirin frames are often seen as not as strong because the keirin frames that are easy to get hold of have often been crashed. but then again, they are specialist frames, not suited to riding on roads. lots of people do though.
