How much is my road bike slowing me down on raceday?

Hi Coach P,

First off, I am aware that the best way for me to improve my speed on the bike is to put the time in on the saddle and being that the bike is my least experienced discipline (began riding regularly in January), I have a lot of work to do.

With that said, I recently completed the 12-week Advanced Short Course training plan and finished the SuperSEAL Olympic Triathlon (first Olympic distance race) on the 19th. The race went as well as my training would allow, finishing 25th overall and 12th in my age group. My swim was 23:32, bike was 1:06:38, and the run was 39:06. What became clear to me during the race was that every competitor who finished in front of me was in a different class on the bike and each one of them was equipped with a high-end triathlon bike while I was cranking my Felt AR3 with clip-on aero bars and stock wheels. The results made that even more clear as my bike time was, minimum, 3 minutes slower than the rest of the pack.

In your experience, how much time could be saved with someone at my level by transitioning to a tri-bike? Or upgrading my wheels? 

I have begun the Get Faster Advanced Short Course training plan in preparation for my second Olympic triathlon in June, which will then be followed by Santa Cruz 70.3 in September. My goal is preform to the best of my capabilities in these races and knowing that I may be losing time not because of my training but for reason of being under equipped has me seriously thinking about making changes.

Any advice would be much appreciated.

    Your road bike and set up is slowing you down a lot!  Get the book called "Faster" by Jim Gourley.  I've attached a graph with the data you are asking about (page 83).  Typically road bikes with clip on aero bars don't fit very well either.  I'd highly recommend a good bike fit. If you have just the road bike with clip-ons and plan to keep it, then get it fit as a TT bike.  EN athletes including myself have used TTBikefit.com.  Look through the forms for other great ideas from bike helmets, clothing etc.  Wind resistance is a real drag :).  See this article also: http://www.triathlete.com/your-aero-edge.  

    The book above has tons of data on wheels, tires, air pressure and other aero choices for swimming, running and biking.

    Lots of other information, so ask away.  Don't want to overwhelm you :)

  • I did triathlons for 10 years with a road bike with clip on aerobars, however I did get fitted with an emphasis on triathlon and one of the things that the fitter did was put a fast forward seat post on the bike which simulated a TT bike somewhat. However when I finally got a TT bike I could tell the difference immediately. The way I had the road bike set up transferred more of my weight to the front and made the bike harder to control whereas the TT bike was easier for me to control even though the fitting was pretty much the same. I didn't get that much faster on the bike leg, but the  geometry of the TT bike meant that I used different muscles and my run was much better off the bike. That's where I made the biggest improvements. I would say that if you know that you want to continue doing triathlon then you should save your pennies and buy a tri bike but you should contact Todd at TTBIKEFIT because he can tell you what tri bikes will work for you, then you can shop around or even buy a used one. There are lots of good deals out there.
  • Thanks for the insight Tom and Mark. Looks like its time for me to do some research.
