Had a fit done on my road bike to try and get more aero. John is very knowledgeable in all the aspects of proper alignment, efficient riding and the importance of comfort in the saddle. He explained well how making an adjustment in one area can impact another. He really understands the big picture and can break it down as it applies to an individual rider. I find that to be rare. A good bike fit can be invaluable to an endurance athlete. If you are looking to up your game see John about a good bike fit to get started!
