Alistair Brownlee’s BMC
Wheels: Zipp Super-9 disc, 858 NSW front
Groupset: SRAM eTap AXS
Frame: BMC Timemachine
Tech notes: Brownlee has been with SRAM and Zipp for about 15 years as he’s won two Olympic gold medals and made the switch from ITU to Ironman triathlon. He’s new to BMC this season. Brownlee opts for the most aero setup with 858/Super-9 combo for wheels, believing the aero benefits are more significant than any weight savings with shallower rims, even on a hillier course. His bike had a 25mm front tire with a 28mm back to optimize aerodynamic efficiency.
