On the front page of every Golf Digest Magazine are the words “Drive It Further!” I should have learned from them a long time ago. I have touched on this many times, but I’ve learned that it takes many impressions to make one.
Frame technology has nowhere to go. The latest generation of carbon frames are extremely light, stiff and forgiving. There is not much you can do to improve them.
Components work extremely well and are very light. Adding a gear won’t make you go faster.
The only thing you can buy that will increase your speed are deep carbon wheels. Period.
Upgrade any other parts of a new generation bike and you won’t go faster. Get some deep carbon wheels and you will. As a bonus, they will make a good looking bike look great.
