Keeping track of position on bike

When I went for Aero Testing on Friday, Xavier said, make sure you keep measurements of your new set up.

Fortunately, I took his advice seriously and did actually do it. Two days later, my aerobars fell apart and, without those measurements, I’d be back to square one.

One way is to take photos with a ruler by the side. Always worth writing down on paper too.

Even if you are not a racer, but just someone who enjoys riding a bike –  it is still worth doing for things like saddle height, fore-aft saddle. If you get a new bike, knowing past measurements is important for keeping continuity between bikes. Big changes in position can cause discomfort, loss of power, even injury.

It’s not the most glamorous job, but important to do.

If you’re a time triallist and looking to eke out marginal gains, it is even more important. Small changes of a few cm, can have big impact on drag factors.

These are my measurements, which will be of no particular interest to anyone, but if I post to my cycling blog, it makes it easier for me to find. And I’m going to use as I put my aerobars back together.

    Tejvan, I use the Parktool position chart pdfs to record these measurements. Nice if you ever build a new bike and need it same as the old one or make an adjustment and it doesn’t work out. You can always get back to a good known position.
