>>1501612This depends on three things:
- your budget
- bike restrictions for the race (such as UCI complaint or Triathlon complaint)
- whether its a mostly flat course or if there are serious climbs involved
If you want to go fuckin fast on a flat ground, aero is everything.
You should go for a Triathlon bike with aerobars, thats a lot faster than any normal drop bar bike.
For rims I'd suggest carbon trispokes, they are the second fastest after disc wheels but don't have the sidewind sensibillity.
If you have to climb a lot, a lightweight bike is everything.
