- 4:15 Dan’s interest in the sea level hour record
- 8:00 sea level vs altitude hour attempts
- At altitude, reduce aero drag by ~20% to 25% (at world record hour speeds) while only losing 10% of aerobic capacity
- The higher the speed the greater the benefit of altitude. That is, the faster the event, the higher up you want to go
- 12:15 at Dan’s speed, 1W saved in his setup = 50m of extra distance in the hour attempt
- 12:30 the physiological demands of Dan’s hour record
- A Watts / CdA of 2250, which works out to ~370W @ a CdA of 0.164!
- Living on your TT bike
- Train at a race-relevant internal inertia (cadence)
- The potential role of central nervous system (CNS) fatigue
- Learning to maintain that optimized position for the duration of the event
- 24:15 the sitting up vs aero tradeoff when climbing
- ~15W benefit to sit up vs aero position, which for Dan makes enough of a difference at ~27kph
- The value of a stretch during a position change is not to be undervalued
- 28:30 the value of efficient cornering
- 30:15 the role of CNS fatigue in performance in an hour record attempt
- Not well understood at present
- Dan’s group is studying this effect by taking measurement of nerve impulses to the driving muscles over time and looking at changes
- 36:45 the effect of non-round chainrings
- 40:00 Dan’s non-aerodynamic optimizations
- The more aerodynamically optimized you become, the more reason there is to look at equipment
- A new, secret crank set
- Drivetrain lubricants, chain, cog and chainring design
- 51:30 Dan’s aero optimization
- Skin suits
- Front ends / cockpits
- Aero sensors
- 74:30 some psychological demands of an hour record bid
