If your goal is to be faster, you will be faster. If your goal is more comfort, he will get you more comfortable. He knows his stuff!!

I had my road bike fit when I lived in North Carolina by a woman whom Michael worked with at Serotta years back. She did make me faster because some of the tweaks she did not only got me more comfort, but more power. After my fit, I was able to keep up on the flats where as before, I always got dropped. It was amazing, actually. It did take a little getting used to (the new position) but once I did, I was absolutely faster. That was ~5 years ago now!

Michael did my fit on my tri bike a few months back before I bought it. From that fit, I had criteria with which to buy the right sized bike with confidence. After I got it, he adjusted it to the specs we found originally and I can say with all confidence, he did a bang up job. I've only ridden it on the road twice since getting it but I was amazed at how comfortable this very, very odd position was for me. It took some getting used to, but even though I was tired when I was done with the ride, I wasn't achey or sore or anything...and that was my very first time on aerobars EVER. He seriously dialed it in perfectly.

I'm a big fan of his and I'd bet dollars to donuts, you will be too after your fitting.
