The Swiss was one of the nine crews who rode the track in Leipzig flawlessly.
Fuchs was also the fastest of all in the time of 65.11.
But when the competitions continue with the second round this afternoon, Chaplin will rest.
Fuchs will instead compete with The Sinner.
- Chaplin is a little older and I did not want to do the whole World Cup with him.
I can share the load between them.
Chaplin is back on Sunday, says Fuchs.
Swedish Jens Fredricson at Markan Cosmopolitan was also flawless in the time 68.41 and is seventh.
