Is that claimed weights or what you've actually measured?Get your scales checked. 545g for an uncut track fork with an alloy steerer is about right - that's what the the 4ZA/Alpina ones weigh. 900g for a L alloy frame is incredibly light for a road frame, I would not be surprised if an Omnium was nearer to 1900 in large.
