Track Forks & Round Blades

[Michael Gordon]

Can someone enlighten me about 24mm round fork blades for track bikes?

Is this just tradition, or is there a purpose behind it.

Thanks!

It's tied to the eras when steel was the material of choice.
Typically, a sprint and kilo frame had 24mm blades while a pursuit and all-around event frame had 22.2mm blades.
This is a generalization, not a definitive statement about what was used across the board.

Yes, my question is in reference to track bicycles, not a latte powered hipster's fixie/urban messenger's delivery ride.

Thanks Richard!

Stiff in every direction and no need to compensate for braking vectors.
