The Stan's ZTR Alpha 400 rim shares the same dimensions and Bead Socket Technology (BST) as Stan's Alpha 340 rim, but adds the triple channel and internal arch design of Stan's strong and durable Arch EX and Flow EX rims for a sturdier rim. The ZTR Alpha 400 offers a 33% thicker spoke bed for maximum durability. Shorter sidewalls and a wide inside rim cavity allows lower tire pressure while maintaining a firm tire feel with decreased rolling resistance and a more compliant ride quality, plus the rim can be run tubeless with tubeless tires and sealant. Light and fast on the outside, ultra-stiff and strong on the inside, the new ZTR Alpha 400 is the rim you've been waiting for. Available in 28 or 32 hole and weighs 425 g.
Weight: 425 grams (32 hole)
