Why are Supersprox - Stealth sprockets better than Aluminum sprockets?
Sprockets made from aluminium are light, their tooth profile will change very quickly because of wear.
Slightly worn sprocket will not engage with the chain properly and it will cause drag.
Chain drag will drain power from your bike.
Supersprox - Stealth carbon steel teeth will last at least 3 times longer than 7075 aluminium sprocket teeth, so your drive system will last longer and run more efficiently.
Add to this the Supersprox unique tooth design, which helps the chain stay in contact for longer and you have a fantastic life versus weight combination.
