Kilo TT's TruVativ uses 130 BCD chain ring.

Track cranks use 144BCD chainrings because of strength issues. A chainring with more teeth will have a larger circumference than one with less, and a larger crank spider will provide a larger area for the chainring to sit on without the chainring flexing too much when it's being pedalled . If you put a 52t chainring on a road crank, it will flex a bit more than the track crank with the same size ring.
