Stan's NoTubes ZTR Alpha 400 Rim (700c)

Stan's ZTR Alpha 400 Rim lets you enjoy the advantages of a tubeless setup on your road and cyclocross bikes. At only 350 grams, it's light, strong, and it features a semi-aero profile for quick accelerations and blazing speed. The Alpha rim also uses Stan's BST technology for easy tubeless conversions, while its wide inner profile and lowered sidewalls boost tire volume for enhanced traction. And this version can be used with rim brakes as well as disc brakes.
