a keirin racer needs all njs parts because anything that isn't njs stamped will break and cause a big crash. NJS stuff is made by tiny japanese men that are like 90 years old and have made bike stuff since the 20's. the best quality, like samurai swords.
the srams are omnium stamped, just like the giant omnium frame. that bike has compact geo and is aluminum so it's bad
plus why mess with square taper IF IT AIN'T FIXED DON'T BREAK IT.
IF IT'S FIXED, DON'T BRAKE IT LOLAMIRITE?
so alumnium's bad... yet most modern track racers use alumnium frames (felt, look, fuji, etc) on the velodrome. Yes, NJS stamps are to certify they comply with the safety and quality standards expected of Keirin racers and their bikes... but it is not a rating of performance.
Also, I don't think "Omnium" is a specific category stamp... it's just the name placed on it, which happens to be the same for the Giant frame. Omnium also refers to a certain track race that consists of multiple races or whatever.
But... yet if you prefer to go and buy all NJS parts because they make you faster, go right on ahead. I'll use the difference of buying a sugino crankset and $80-100 BB for a much cheaper yet equivalent (if not better) crankset.
