When a respected BMX company like Alienation decides to manufacture a carbon race rim, you know that they are going to be the business, and they haven't failed to deliver. The Alienation Carbon Acme-UD is light! At just 260 grams, these are some of the lightest 406mm carbon race rims available on the market now. You can choose a front and rear specific rim (rear rim has a braking surface), or if you are running a disc brake set-up, you can run two front rims for a smooth, matching look.
