Product details
WHAT IS THE SUPERSPROX-STEALTH ABOUT? |
|
|
Supersprox-stealth is about longer life, without compromising weight. 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 foot pound (ft/lbs), Supersprox-stealth is the best. |
|
BETTER THAN ALUMINIUM SPROCKETS! |
|
|
OK, this is no contest! Try 20,000 miles on a Hayabusa with an aluminium 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 gruelling challenges. Don’t waste your money on aluminium, invest in Supersprox-stealth. |
|
WILL A STEEL SPROCKET DAMAGE MY CHAIN? |
|
|
This might sound like an unusual question, but there’s a lot of misinformation out there. When you think about bearings for an example. They`re steel on steel and that works great. Steel on steel is the best combination. So when a dealer tells you steel teeth can damage your chain, ask yourself if they only sell aluminium sprockets. |
|
ARE THE RIVETS STRONG ENOUGH? |
|
|
There is no doubt, riveting is the only possibility for fixing such a high performance sprocket. We know how to use this technology, forging rivets into the sprockets. We have never had one single rivet break since starting to produce these sprockets. That’s over 5 million rivets in the past 11 years. |
|
|
Its perfect for any bike up to 1400 cc. Do you have a powerful 4 stroke or performance street bike? Covering high mileage or road racing, then this is your best option. A single sprocket can last more than 20,000 miles (See maintenance instructions). Whatever your bike, if you want peace of mind and the knowledge that you have the best of the best, then choose Supersprox-stealth. |
