Supersprox SPX Stealth 808.4:47

The crowns: Step 520 - 47 teeth SUPERSPROX Stealth have a lifespan three times longer than an aluminum crown, without compromising performance. Better than steel! You cannot achieve this level of durability with a steel crown of the same weight. Of course, there are lightweight steel crowns, but they cannot handle the torque. Better than aluminum! Try riding 20,000 miles on a Hayabusa with an aluminum crown or completing the entire Dakar Rally on a crown wheel. For extreme racing, factory teams rely on SUPERSPROX Stealth crowns. Are rivets strong enough? There is no doubt that rivets are the only way to secure such a high-performance crown. We know how to utilize this technology by forging rivets into the crowns. Since the beginning of production, we have never had a single rivet break. Over the last 20 years, more than 6 million rivets have been used. Drawing and image are non-binding.
