N.J.S. (Nihon Jitensha Shinkokai-the Japanese Bicycling Association) is the governing body of Keirin racing.
They have very strict standards, with the intention of preventing mechanical failure and "leveling the playing field" among the athletes.
Not all of the N.J.S. standards actually relate to quality as such, but rather act to promote interchangeability of parts and tools.
N.J.S. threading and sizing standards are generally the same as Campagnolo track parts.
von wikipedia:
As a result of the parimutuel gambling that surrounds keirin racing in Japan, a strict system of standards was developed for bicycles and repair tools. There are currently 50 velodromes in operation that hold races where annually over 20 million people attend and place bets amounting to over ¥1.5 trillion($15 billion) .[citation needed] Since so much money is at stake, the NJS requires that all keirin racers in Japan ride and use equipment that meets their standards. All riders use very similar bicycles, so that no rider will have any advantage or disadvantage based on equipment. In addition, all riders must pass strict licensing requirements.[specify]
All bicycles and equipment must be built within strict guidelines set by the NJS, by a certified builder using NJS-approved materials. The products are then stamped by NJS and only equipment bearing this stamp may be used. However, it should be noted that the NJS standard is to ensure that no rider will have any advantage or disadvantage based on equipment, and does not necessarily relate to quality or standard of manufacture; e.g. 36 spoke wheels are allowed but not 32, and frames must be built by a very limited number of approved builders.
NJS approved equipment often sells for triple the price of comparable equipment because of its popularity in Japan. NJS equipment can usually be obtained more cheaply outside Japan, in places like the US, Germany, France, or Italy, where advanced technologies such as carbon fiber are more popular and more commonly used in racing than the steel required of keirin. However, NJS frames are still much more expensive than their advanced-material counterparts. Popular manufacturers include Samson, Nitto, Bridgestone, 3Rensho,
Shimano, Nagasawa, LeveL, Panasonic, Hatta, MKS, Kashimax and Sugino.
NJS-approved equipment is not required for keirin races outside Japan.

Inzwischen hab ich noch nen 100er Vorbau und einen Cinelli Pista Lenker montiert (auf dem Bild ist es ein 120er). Jetzt stimmt auch die Länge mit ihrem alten Bahnrad überein. Sollte also gehen. Aber Tatsache bleibt natürlich: Eine RH kleiner wäre besser gewesen (oder eben eine größer für mich! Dann wär die Sache eh klar gewesen
