TheRNC Aluminum Cranks are made from a fancy aluminum that keeps them stronger than other alloys with a higher strength to weight ratio than titanium. The man over at RNC comes up with some pretty nifty products if you’re looking to get a super light bike that maintains its strength. With that said here is his take on his cranks with all the fancy stuff you need to know.

***Also take note these only work with RNC 24mm bottom brackets and sprockets. Apparently every other BMX brand does not use an actual 24mm sizing. However the bottom bracket is included, and you can find the proprietary sprocket here or the bash guard version here. ***
