Details here in the comic:

Does this apply to regular race bikes as well as the TT machines?

Will this apply to the track too, if so, Wiggo's hour record might not last for much longer...

Drag saving won't be huge I doubt if they do apply it to track bikes. Not enough for someone average to now break his mark.

I wonder if it will last as long as disc brakes?
