One of BMX racing's most trusted products! Sun has been manufacturing these double walled alloy rims for years and haven't had to mess with the formula. Made from 6061-T6 aluminium, the Sun Envy rims have nipple eyelets to add strength to this part of the rim. Dependable and great value, these are a popular choice for BMX racers still building wheels with alloy rims.
