2 度の股関節置換手術によって私の自転車のフィット感が永久に変わりました。

My cycling position and bike fit completely changed after my hip operations. I went from riding in an extremely upright position and knees out motion to getting down low and keeping my knees in tight. I’ve had two total hip replacements in the last 9 months. My left side was done in November 2024 and my right side in April 2025. The effect on my cycling position and bike fit has been dramatic. How much have things actually changed? Well, I’ve got some before and after video to show the difference. First, I can see from some old video that my usual torso angle was more than 45°. Now, after my operations and with a saddle tilt, I can get down under 40° of torso angle. And if I dare venture into the drops, my new position is completely uncharted territory for me with a torso angle in the low30s. Here is what I used to look like in the drops. What about from the front? Again, my arthritic hips used to push my knees out a long way, well over a 10° angle from vertical. Yes, I could bring them in closer if I tried, but it wasn’t sustainable and it made the pain after riding much worse. Now I’m able to keep my knees pushing vertically and can even bring them into a negative angle close into the top tube. To be fair, this does still feel a bit weird, but it doesn’t hurt. I don’t think I am a particularly vain cyclist. However, I was always conscious that I looked different, maybe even awkward on the bike. My hip operations have definitely improved my cycling aesthetics when riding, in my own humble opinion, of course, but more important is how does this change and improve my cycling performance? I’m not really expecting any gains in power output or FTP because I never felt my hip issues reduce my strength or endurance, but I will be very keen to see how my speed on the flat and downhill roads change now that I can get into a much more arrow position. Maybe I’ll be able to keep up with my group more easily on the flats. When I had a Wahoo Sufferfest membership in the past, my rider profile usually came back as time trialist. I thought this was hilarious because there is no way I could ever hold position on a time travel bike. Obviously, the Wahoo app has no idea about my position on the bike, just my output. Now, I’m starting to wonder if maybe I could get into a time trial position. So, in summary, while I decided to have my hip replacements to deal with the daily pain I had, I’m quite enjoying the fringe benefits that the extra flexibility gives me. Looking forward to joining the cool kids with their slammed -7° stems. Now, if you’re interested in the journey from deciding to have a hip replacement through the operation and then the first six weeks of recovery, I’ve made a series of videos on my experience with the first operation. Links in the description below. Hope to see you in the next video.

When I had my first total hip replacement 9 months ago, I was relieved to be free of the pain. When I had the second hip done 10 weeks ago, something else amazing happened! I was almost immediately able to bend forwards and get into an AERO position on my bike.
After decades of worsening hip pain and stiffness, I was resigned to the fact that I needed to sit up tall on my bike for the sake of comfort. This position was so inefficient and uneconomical, and I often struggled to keep up with my mates on the flats and especially downhill roads. The only place where I wasn’t punished for my inflexibility was on steep hill climbs where aerodynamics don’t matter.
But now, even in the early stages of my rehab, I can really see just how much my cycling position has improved. I’m pretty excited about getting back to full fitness and rejoining my regular group rides, to see just how much benefit this reduced frontal surface area will provide me!
