Biggest Bang For Your Buck In Time Trial Equipment

With the Church Creek Time Trial coming up this Saturday August 17th and the Parvilla Time Trial Series approaching on August 28th, many people have been looking at how they can gain those extra seconds out on the road.  Aside from a good structured training program, what else can you do? 

The speed you can achieve on your bike is determined by two factors:

1. How much power you can produce

2. Wind resistance.  The faster you go, the more wind drag you need to overcome.

There was an excellent article in Velonews about which aerodynamic equipment benefits most during an individual time trial.  What they didn’t do is rank the cost vs. benefit for each piece of equipment and the associated time savings.  Years ago I saw something like this done by cyclingnews and found it extremely interesting.  Unfortunately it’s buried deep in the internet and is lost forever so Cycling Tips rehashed it for those of you who missed it.

The following chart shows the aerodynamic savings according to what www.aerosportsresearch.com calculated for Velonews.



A couple notes:
- These numbers are calculated for a rider over 40kms at a time of 48minutes.  Faster than most of us could go!


Biggest Bang For Your Buck?

1. Using aerobars that allow you to get into a tuck position will be the cheapest thing you can do for the aerodynamic benefit.  You can get a set of aerobars for $100 and they’ll save you a couple minutes in a 40km TT.

2.  Positioning on the bike is key.  Without the benefit of a good bike fit you will never be able to maintain an aerodynamic position in the aerobars or produce the power to overcome any wind resistance.  You can get a bike fit for $400 from Stu Waring at Parvilla Cycles, he is the only Retul Instructor in the US that does not work out of Retul HQ in Boulder! Not only will it save you minutes in a 40km TT but it will also make your cycling more enjoyable!

3. Getting a skinsuit will provide massive benefits.   The only disclaimer is that the testing shown here was done on a specially designed skinsuit for Nike, not a standard skinsuit.  I’m sure this skinsuit costs in excess of $1000, but you’ll realize large gains with a standard skinsuit as well.    The chart above shows an extreme comparison between this Nike skinsuit and regular jersey/knicks in windtunnel testing.

4. Shoe Covers will cost you no more than $50 and could save you half a minute in 40kms.  Shoe covers smooth turbulent air over the straps and buckles of the shoes.

5. Upgrading from a regular helmet to an aero helmet could save you over a minute for a $200 spend.

6.  Time Trial Wheels are getting into the expensive end of TT equipment spectrum, but they do provide some good time savings and look very PRO.  Having an aero front wheel will make the most significant difference and will cost the least of the two.  Most of you probably already have a set of deep dish aero wheels for racing anyway.  A rear disc wheel is one of the last items you should spend lots of money on if you’re looking for big savings.  However, if you want to look cool this should be the first item on your list  ;-)
