Q: DOES VORTEX MAKE A STEEL REAR SPROCKET?
A: we focus on high performance race parts and therefore only manufacture aluminum rear sprockets
Q: HOW CAN I GET A SPROCKET FOR AN AFTERMARKET WHEEL?
A: these are available by telephone order only at 800-440-3559. You may want to have the old sprocket handy for a quick measurement.
Q: WILL AN ALUMINUM SPROCKET LAST AS LONG AS MY STOCK STEEL SPROCKET?
A: usually not. Aluminum is for high performance and the light weight compromises longevity. The biggest factor will be the quality and care of your chain; if it is worn or poorly maintained it will wear out your aluminum sprocket.
Q: WILL A VORTEX ALUMINUM SPROCKET HOLD UP ON MY DRAG BIKE?
A: YES! Many AMA Prostar drag teams swear by Vortex lasting longer than competing brands.
Q: HOW IS A VORTEX SPROCKET MADE DIFFERENTLY?
A: there are many ways Vortex is constructed to keep it lasting longer than others. One way to ensure tight concentricity is to eliminate the time-saving method called 'gear hobbing' and keeping the material stationary throughout it's complete construction. This ensures a tighter tolerance; thus making a longer lasting sprocket and freeing horsepower. We also have our own unique tooth design that we've created to reduce wear.
Q: HOW MUCH LONGER WILL THE F5 SPROCKET LAST?
A: we tested the hardcoated sprockets on the Jordan Superbikes to last 30% longer than our standard sprocket. And that was before we thought to coat the sprocket with PTFE!
Q: WHAT IS PTFE?
A: simply put, it is a friction-free coating similar to a non-stick cooking pan. When coupled with the hard anodizing, this will keep your sprocket cleaner and lasting longer. Click here for technical info on PTFE.
