My Cycling Passion and New Wheels Experience
My passion for cycling started about five years ago. Each year, I found myself spending more and more time in the saddle, until eventually, after years of fine-tuning my touring bike, I decided to buy a road bike. That’s when I realized this was the kind of cycling I truly enjoyed.
At first, I used a DT ERC 1400 45 mm wheelset — and I still do today. It’s an endurance-focused wheelset weighing 1465g. I wanted something lighter, but at the same time deeper and stiffer. For a long while, I couldn’t find anything that matched what I had in mind — until one day I came across the Light Bicycle Airia series. I instantly knew that they were what I wanted.
After lots of research, I decided on the 55 mm depth, which would save a bit of weight while giving me the deeper rim profile I wanted. For me, that combination was exactly what I’d been looking for. The customer service at Light Bicycle was excellent — very helpful and patient, answering every single question I had, which was quite a few. The production time ended up being a bit longer than expected, but they informed me about that upfront. Totally worth the wait.
The wheels arrived in perfect condition, and I was genuinely excited to unbox them. Right away, I could feel how light they were in my hands. The matte finish was flawless, and the build quality felt perfectly balanced. I fitted Aero 111 – 29 mm tires on the front and Continental Grand Prix 5000 TT TR – 28 mm on the rear. Both went on by hand — no tire levers needed, thankfully. I seated them with a compressor, then deflated, removed the valve cores, added 35 ml sealant, and pumped them back up with a hand pump. Gave the wheels a quick spin, and that was it — a clean, easy setup. After that, I swapped the brake rotors — no adjustment was needed. After the test ride, the tires measured: Aero 111 29 mm → WAM 29.3 mm / GP TT TR 28 mm → WAM 31.3 mm (@ 64PSI / 72 PSI). The next day, I went for a proper 140 km ride.
First Impressions of the Wheels
The first thing I noticed was the sound — brilliant. Deeper, louder, with a nice resonant hum — totally different from the DTs. The wheels’ stiffness was immediately noticeable: steering felt much more direct and precise. Even during out-of-the-saddle sprints, the bike felt sharper compared to my previous wheelset, which felt a bit muted. In terms of acceleration and responsiveness, it’s roughly on par with my previous wheelset (with TPU tubes), but the comfort is on another level. Despite being a stiff wheelset, the tubeless setup and pressure smooth out the road beautifully — very refined. Later, I’ll try them with regular GP 5K + TPU tubes, which will make them even lighter. I suspect that’s when they’ll truly show their full responsiveness compared to the DTs, since the current setup adds a bit more rotational weight due to the tires.
Crosswinds: When buses or trucks passed, I barely felt anything. The bike stayed perfectly stable — actually, I’d say it feels even more stable than the DTs with GP 5Ks.
Buying Goal Achieved
I wanted a lighter wheelset, but also deeper than my current one (that was non-negotiable). My existing wheelset looked a bit too slim aesthetically, and I also wanted something stiffer. These Airia 55s will serve as my summer wheels, though I mounted them right away to try them out — and I absolutely love the look of the new wheels as well. I’m very happy with them — every kilometer is a joy. It honestly feels like having a brand-new bike again.
P.S. Thanks to the Light Bicycle team!
