EZ Aero Chainring Guard®
EZ Gains® has also addressed another area of the bike that can slow you down: the chainring. Just like with your wheels, air can get caught in the open space around your chain ring, creating drag. So they created a simple, cost-efficient carbon fibre cover that slips over most setups—offering aerodynamic gains without the high price tag.
