1. With growing consumer demand for high-value carbon fiber wheelsets, LightFast has developed and launched the LF A50 series—offering exceptional cost performance, high quality, and an attractive price.
At the same time, a growing number of cyclists are showing a preference for wheel sets with steel spokes, which offer greater flexibility and durability.
At this very moment, the LightFast LF A50 steel-spoke wheelset series emerges to meet this demand, delivering an even more comfortable riding experience for cyclists.
To shorten delivery times and prevent customers from waiting too long, the LF A50 steel-spoke wheelset series is now prioritizing its most popular rim depth option—the 50/50mm LF A50, which has a complete wheelset weight of 1323±30g.
2. Below is a cross-sectional view of the rim. The 50mm indicates the rim depth (rim height), with an internal width of 23mm and an external width of 31mm. The most popular 50/50mm rim depth delivers an ultimate riding experience to cyclists. The mainstream internal width of 23mm and external width of 31mm not only accelerates delivery capability but also saves riders from the hassle of repeatedly selecting specifications.
3. The LF A50 wheelset offers a variety of logo styles and colors: laser-etched LF logo, traditional regular script in black and silver, and cursive script in black, silver, or gold—each reflecting the understated elegance and premium character of LightFast wheelsets.
Of course, to match your unique frame with a low-key and understated style, we are also happy to provide a clean version without any logo (please note, however, that there will still be a very small logo on the hub, which will not affect your overall design coordination with your frame).
4. LF A50 uses Aero-grade Toray 800 +Toray 1000 original carbon fiber materials, precision braiding and high temperature molding to create the ultimate lightweight wheelset. Every gram of weight reduction is to make you ride faster,farther and easier.
5. The LF A50 carbon fiber wheelset, with a 23mm internal / 31mm external width, U-shaped aerodynamic design, and Belgian top-grade steel spokes. Sapim CX-Ray delivers enhanced cruising performance and quicker acceleration.
6. Equipped with the latest 36-tooth ratchet system, steel bearings, and a precise 10° engagement angle, the LF A50 Hub System ensures that the LightFast hub continues to provide cyclists with uncompromising power transfer.
7. LF A50 uses ultralight Belgian top-grade steel spokes. Sapim CX-Ray: combines the features of excellent aerodynamics with low weight and great strength.
8. LF A50 Tyre Compatibility
The latest back-hole-free process eliminates the need for tubeless tape or rim tape.
Compatible with regular clincher tyres with innertubes and tubeless -ready tyres from leading manufacturers. From 25-43C tyre, the best recommand are 25C or 28C type.
9. LF A50 Rider weight limited attention: Lightfast Wheelsets have a maximum weight capacity of 120kg (including Bike & Rider & Personal belongings).
10. The video below shows LF A50 50mm wheelset undergoing an impact test, where it withstands up to 120J of impact energy. For comparison, the UCI standard requires only 40 J. That means the LF A50 delivers impact resistance of roughly 3 times the international benchmark.
