Name : Kristi Kuldkepp

Profile : Cycling isn’t just an activity for me – sport in general, has always been a part of who I am. Having not started cycling until I was 31, I’ve been lucky enough to race professionally as part of amazing teams, and to win a Gran Fondo European Championship. More recently, I also won a European cyclocross championship, too. Over the years that I have been cycling – not only at my home in Estonia, but also in Europe and Belgium in particular – I’ve witnessed the beginning of changes for women’s cycling, which still has a long way to go. I’ve raced with and met some truly inspiring individuals, and I get to travel to race, sharing my cycling life with friends and others.

First Impressions for Gravel Riding

Over the past few weeks, I’ve been using the Light Bicycle Turbo 50 disc wheelset extensively during gravel training rides, and my first impressions have been extremely positive. These days we can start to look away from the more well-known wheel brands, safe in the knowledge that there are some extremely technical and well-made wheels coming into focus for the right reasons – including performance and price point.

Although my first gravel races with these wheels are still ahead, they’ve already proven themselves to be fast, confidence-inspiring, and exceptionally well-built. All critical issues for training and racing, when you have to rely on your wheels for those marginal gains. Did you know that wheels are the most common upgrade for cyclists when they buy a bike.

The first thing that stood out with the Light Bicycle Turbo 50 disc wheelset was how responsive the wheelset feels. Despite the 50 mm rim depth, acceleration is quick, and the wheels feel lively when putting power down. Whether accelerating out of corners or riding short climbs, they respond instantly and feel very efficient.

Gravel Riding Performance Wheels

Gravel riding can be a different beast for wheels. Thankfully though, on faster gravel roads, the Turbo 50 disc carries speed remarkably well. Once the bike is up to speed, maintaining momentum feels effortless. The aerodynamic rim profile gives the bike a fast, smooth feeling, especially on those long and challenging open gravel sections. At the same time, the wheels remain surprisingly stable in crosswinds, providing confidence even in the more exposed conditions. This aligns with the design intent of the Turbo rim profile, which aims to improve aerodynamic efficiency while maintaining crosswind stability and lateral stiffness. It’s refreshing when a product fits and works as it was intended to.

The 25 mm internal rim width is also an excellent match for modern gravel tyres. I’ve been riding them with wider gravel tyres, and the tyre profile feels well supported, allowing lower pressures for improved grip and comfort without sacrificing cornering stability. The bike feels planted and predictable over loose gravel, rough roads, and when heading into fast corners. Another aspect I’ve really appreciated is the ride quality. The wheels strike an excellent balance between stiffness and comfort. They feel direct under power while still absorbing road chatter well enough to keep long training rides comfortable. Tubeless setup was straightforward, with the tyres seating easily and maintaining pressure consistently – viola!

Quality and Performance in Balance

The overall build quality is exactly what you would expect from a premium carbon wheelset. Light Bicycle is a well-respected brand and focuses on technology and innovation. The finish of their Turbo 50 disc wheelset is clean, spoke tension is even, and the wheels also arrived perfectly true – definitely a rare occurrence. Every detail reflects a high level of craftsmanship and scores positive points for me.

Highlights so far

  • Fast acceleration despite the 50 mm rim depth.
  • Excellent speed retention on fast gravel roads.
  • Stable and predictable handling in crosswinds.
  • Stiff under power while remaining comfortable on rough surfaces.
  • Wide rim profile pairs perfectly with modern gravel tyres.
  • Easy tubeless setup and reliable air retention.
  • Outstanding build quality and finish.

Looking Ahead to Race Day

While I haven’t raced on the Light Bicycle Turbo 50 disc wheelset yet, my training experience gives me plenty of confidence heading into my first gravel events. Based on everything I’ve experienced so far, I expect these wheels to be an excellent choice for riders looking for a lightweight, aerodynamic, and reliable gravel racing wheelset. If they perform in racing as well as they have during training, they’ll be a wheelset I’ll be happy to keep using for a long time – and that has to be a good recommendation.
