Lace up some Stan's ZTR Flow EX rims and get after it. These hoops are tough enough for aggressive trail riding, downhill racing, and all-around hard charging yet still light enough to be pedaled back up the hill. The Flow EX also uses Stan's BST technology for easy tubeless conversions, while its wide inner profile and lowered sidewalls boost tire volume for enhanced traction. Want your all-mountain trail rig or enduro ripper to be faster? These rims can help!
Stan's NoTubes BST design creates a tight tubeless seal between the rim wall and tire bead. The inner rim wall is the same size and shape as the tire bead. It's also shorter, which increases the volume of the tire.
