Actually most road race bike are also in 14-17mm of flop range with a trail number hovering between 55 to 58mm. My old dolan df3 is the road/track bike that i rode with the biggest trail number at 66mm (tied with some gravel/cyclocross bikes)
Trail, top tube length, stem length and chainstays length are what make the handling of any bike. My dolan DF3 was still twitchy because i had a top tube 2cm shorter than what I should ride normally like my Felt TK FRD 55cm.
For short tail helmets suitable for match sprinting, you have the choice of:
Lazer wasp air or the newer(and shorter tail) Victor
Giro Aerohead
Poc Cerebel
Oakley Aro7
