Sprocket Rear Stealth Gold 39T for 520# Chain

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 Alluminium 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.

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.
