Mirinda Carfrae is the 2010 Ironman Hawaii World Champion. In 2011, she came in second place behind Chrissie Wellington, who has not come back to defend this year. So for 2012, we think it's fair to say that Rinny is the defending champ. She sat down with TriRig for an exclusive interview about her year, her form, and her new Felt DA bicycle. Check out the video interview in the article, and our gallery of her stunning bike below. Her sponsors, especially Felt, Zipp, and SRAM, have demonstrated a commitment to helping her achieve her optimal position aboard the uncommonly-small 650c size. There are some special bits on the bike related directly to this goal, as well as some prototype parts that may reflect the future of the components on her rig. Make sure to check out the captions for all the inside info.
Okay, you didn't hear it from me, but there are only 10 teeth on that small cog. This cassette is labeled as SRAM Red, but I doubt this thing will ever see production. 10-teeth cogs aren't typically used because they come with their own fitment and compatibility issues, but this may have been the only way to give Rinny the gearing she needs on a 650c bike, without resorting to the 58-tooth chainring we saw her on a couple years back. Using standard chainrings gives her more reliable shifting up front, and allows her to use a complete YAW-compatible setup with her new SRAM Red drivetrain.
