Last week, in my previous post, I described the power delivery optimisation that I did for my friend Steve, to show how much faster he could go just by changing when he pushed harder on his favourite bike route and when to ease off. I followed this up with a quick study to show how much benefit could be achieved with certain bike and kit upgrades.
The analysis I did was basically the same as the 2016 analysis, except it was done for Steve's lunchtime bike route, instead or three generic bike ride profiles. The results are shown in the bubble plot above. I've shown it with upgrade price on the x-axis, and the equivalent power saving in the y-axis. Items that represent the best value for money (Watt saving per £ spent) have the largest bubbles.
The conclusions are similar to those in the 2016 blog post. Buying latex tubes represents excellent value for money, probably the best there is. On the other hand, paying extra money for a lighter groupset (if it has no additional functional benefits) is a really bad way to spend your money, if improved cycling performance is your priority.
