Below are the main products I use to complete Ironman Triathlons, Bikes, Shoes, Wetsuits and Fuel!
The Cervelo P5 is main triathlon bike, a bit dated at this point, but still gets the job done. Cervelo is a really good triathlon brand, excellent scale and a very high focus on aerodynamics. The P2 has always been considered a very good value and an excellent entry bike into the sport.
Parlee Z3 (Custom)
The Parlee Z3 custom carbon fiber bike has a smooth ride that keeps you going all day. There are more aero bikes, but the bike is very light, and very fast. I have had some great days on this bike including the 2012 Harpoon B2B ride see link to strava https://www.strava.com/activities/10996381.
Both Bikes were purchases at Fitwerx
