Lightweight, Tubeless XC Performance!
The legendary Crest is now even better. Wider and even lower profile, the new Crest MK3 rim sheds weight for faster acceleration and climbing. WideRight 23 mm internal width increases tire volume for improved stability with wider tires. Inspired by Stan's carbon technology, the entirely new rim shape adds strength and virtually eliminates the chance of a tire pinch flat.
Refined over the past 15 years, Stan's NoTubes Bead Socket Technology offers the most trusted tubeless seal in the business, making the Crest MK3 the best choice for lightweight, tubeless XC performance.
WideRight - The most important piece to the bicycle-terrain interaction is the contact patch between the tire and terrain, so tire profile and tire pressure play huge roles in bicycle performance and overall handling. But many rims just don't work well with the tires we're all using. Rims that are too narrow fail to offer sufficient sidewall support and protection to your tires and create a less stable shape. The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tire profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tire's volume. Stan's WideRight rim widths are designed to strike the perfect balance between tire volume and sidewall function.
Bead Socket Technology rims are designed to match the shape of your tire's bead to create a safer and more secure air tight interface. Unlike the secure "socket" of a BST design, conventional rim shapes drive the bead of the tire down deeper into the rim, putting pressure on sidewalls that causes friction, restricts tire volume, and keeps the interface from forming a sufficient seal for tubeless use. BST rims secure the bead of the tire, not the sidewall, creating an air tight seal while allowing the tire's sidewall to expand to its true, rounder, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, BST rims are also lighter and stronger by design, and accelerate more quickly.
The hubs are the new Stan's NEO with aluminum freehub body. The Neo brings you 4 pawls with simultaneous engagement, 36-Points of contact and resulting 10° of engagement.
Also they comes with oversized bearings for maximum durability.
Easy tubeless use with pre-installed Stan's NoTubes yellow tape and matching valve.
