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?
Kind of stupid 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 aluminium sprockets. We guarantee our sprockets. If they don't do what we claim, you can have your money back.
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 rivers in the past 11 years.
It's for your bike!
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.
