WHO IS DARYL FITZGERALD?
Daryl Fitzgerald fits riders at the sharp end of the World Tour and brings that same eye to amateurs. His recurring point on the podcast is that the single highest-return change most amateurs can make isn't a power upgrade — it's a position that stops fighting them. A good bike fit protects the knees, lower back and hands that take the beating over long rides, and it quietly unlocks an aerodynamic position the rider can actually hold. He's the practitioner's counterweight to the kit-buying instinct: fit first, then everything else.
FITZGERALD ON AERODYNAMICS
Fitzgerald’s key positions on aerodynamics.
- The one change most amateurs should make is a proper bike fit — saddle height and cleat position fix more problems than any component upgrade.
- An aggressive aerodynamic position is worthless if you can't hold it — fit determines how much aero you can actually keep.
- Knee pain, lower-back pain and numb hands are usually fit problems, not weakness problems — chase the position before the physio.
IN FITZGERALD’S OWN WORDS
Verbatim from Daryl Fitzgerald’s appearances on the podcast.
“I had an Australian client last week. He did they got this 20k time trial loop that they do every Tuesday or every second Tuesday. He sent me a video. I said, 'Your saddle's a touch too high.' He literally dropped it by I think it was 7 mm. The same loop for three watts difference. He went a minute quicker.”
“I've had one or two clients like elite athletes back home in South Africa go to shorter cranks and lose 20 30 watts immediately. I say put your old cranks back, do the same session, straight back to normal.”
“Don't don't be scared, but don't go five or 10 mm at a time. Go one mm at a time. It may only sound a little bit, but you'll definitely feel the effects. And for me, try and do little things like when you're riding, feel if your glutes are working.”
