LightFast Super Light Steel Spoke Wheelset -LF A50 DISC Brake

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.
