Hi,

I was going to buy the 60/80 combo for wheels but then yesterday I watch the Kona Ironman and a lot of people had the 80/80 combo. Why?? and last year if I remember correctly they all had the 60/80 combo. I will be doing my first Ironman Florida next year it will be all flat but I guess it could be windy. I'm about 5' 11" and should be around 170lbs - 165lbs. What should I purchase?

Thanks.

The 80 combos you saw on the following athletes were the Mavic CXR 80's: Fred Van Lierde (men's winner), Starky (fastest bike split), Tim O'Donnell (top American finisher) and Leanda Cave (defending women's winner).

These particular wheels are very stable in crosswinds. If you're interested, here is a test I was fortunate to complete in Kona on the Wednesday before race day out on the Queen K with one of Mavic's engineers gathering yaw angle information out on the race course (http://www.engineerstalk.mavic.com/yaw-angle-measurement-in-real-conditions-on-kona-ironman-course/).

The ride took place on Wednesday of race week which turned out to be a more severe weather day than what the pros experienced on Saturday however by many accounts the winds really picked up when the majority of age-groupers were out on the course.

To more directly answer your question about Ironman Florida, Starky followed up his fastest bike split in Kona with an Ironman record setting ride in Panama City (4:02:xx) with a Mavic CXR 80 front and a Comete disc.

There was a pretty wide range of wheel choices both last year and this year at Kona. Among pros and top Agers. I'm not sure where you got the impression that everyone was using 60/80 last year and everyone was using 80/80 this year.

Your wheel selection is basically going to come down to your ability to handle the wheel set in the wind. Some wheels react different than others, and some riders have a higher tolerance based on their position and handling skills.

In general though...someone of your size can probably handle a 80/80 set. Unless you're a BOP rider...where a shallower set may help due to the increased yaw angle of the wind you'll experience.

Thanks for the info. I think I will go with the 80/80. I'm wondering what is you guys info about the made in China brand. I don't have a lot of money to spend on these wheels and you can buy both wheels on e-bay for about 500$ any thoughts on that? I know it can't be compare from the real brand but I'm pretty sure it's better than my Cannondale Slice 5, 2011 stock wheels.

Thanks!

The difference between stock (box) wheels and high quality aero wheels can be significant. The difference between aero 60/80 vs 80/80 combos is very small and 80/80 may not always be better. I would get which ever looks best to you on your bike and ride the heck out of them.

The Chinese wheels may be fine, or they may not be so great. You can get great wheels from Orr, Flo, Williams, or Boyd and at least have someone to talk to if you have issues. If you are willing to take the chance to save money, go Chinese.

Disclaimer. I have to admit, I have purchased a bunch of Chinese knock-offs including water bottle cages, lights, pedals, heart rate straps, speedometers and cadence monitors and have only been burned a couple of times. I have never bought Chinese wheels

80/80 should be more aero as long as you feel comfortable with them in a crosswind. 

I'd look for a set of Flo wheels if I were you. When/if I ever get around to buying some decent wheels I will likely go with Flo. I'l order the 90/90 and then get a disc cover for the back wheel.

My back wheel needs to be trued up. It has a slight side-to-side wobble, and I feel at times like I'm going to lose control when I ride. Is this something that I should only trust to my LBS to do?

The wheels are my first area of concern and I have started to shop around. I find it nauseating to think of spending the same amount for wheels as my bike. Any help?

Being a fast swimmer put me up with the faster athletes. As expected, they started to pass me soon out of transition. Some would just slowly pass. Others with aero wheels would literally buzz by.

This article estimates how much time can be saved in sprint races by converting from stock aero wheels found on most tri bikes to more aero disk and composite spoked wheels.
