Supersprox Stealth was developed for riding in extreme conditions, where aluminum sprockets can't handle the torque delivered through the chain drive system. Supersprox engineers conceived and developed the combination of the two materials in the millennium year. Supersprox have counted 12 world titles since that time and 2005/06/07/09/10/11/12/13 Dakar wins.

What is the Supersprox Stealth about? Supersprox Stealth is about longer life, without compromising weight. The primary goal; to last 3 times longer than an all-aluminum sprocket and remain as light as possible. It's about performance and function first and last.

Better than steel! Supersprox Stealth is infinitely better than steel! You just can't achieve this level of strength on a steel sprocket with the same weight. Sure, there are light steel sprockets out there, but they can't handle the torque. Pound (lb) for pound foot (lbs/ft), Supersprox Stealth is the best.

Better than aluminum sprockets! OK, this is no contest! Try 20,000 miles on a Hayabusa with an aluminum sprocket or the whole Dakar rally on one sprocket. What about the Baja 1000? These are extremes and factory teams actually buy Supersprox Stealth for these grueling challenges. Don't waste your money on aluminum, invest in Supersprox Stealth.

Will a steel sprocket damage my chain? Kind of dumb sounding question, but there's a lot of misinformation out there. So, think about bearings for example. They're steel on steel and that works pretty well. Steel on steel is the best combination. So when someone tells you different, you should ask if they only sell aluminum sprockets. Supersprox guarantees their sprockets. If they don't do what Supersprox claims, you can have your money back.

Are the rivets strong enough? There is no doubt that riveting is the only possibility for fixing such a high performance sprocket. Supersprox knows how to use this technology, forging rivets into the sprockets. Supersprox has never had one single rivet break since starting to produce these sprockets. That's over 5 million rivets in the past 11 years.
