Crest rims are part of the history of mountain biking. Introduced in 2005, the Crest's design evolved directly from Stan's earliest ideas, including the legendary 355 rims. Stan wanted a simple and durable rim that would work well without a tube and weighed less than everybody else's rims. The Crest achieved those goals. With a more durable and lighter 6069 alloy and an asymmetric rim shape that balances spoke tension, today's Crest MK4 has technology that's lightyears ahead of the early design, but the spirit of the original Crest lives on: make it light, make it serviceable, make it resist flats, and make it go as fast as possible.

The BST-Asymmetric rim design of the Crest MK4 allows for a stronger wheel while offering the easy inflation and Stan’s trademark unmatched airtight seal. The Crest MK4 rim is optimized for 40mm Gravel tires and up to 2.3” mountain tires, making it a great, versatile choice for a wide range of bikes and riding styles.

The durable but forgiving ride of the Crest MK4’s 6069 alloy construction and lightweight, low-profile rim shape offer an unbeatable ride quality uniquely suited to Gravel and short-travel XC riding, and like all rims that bear the Crest name, it’s built for speed.

The Crest MK4 combines the heritage of Stan’s legendary tubeless design with today’s best materials and a stronger asymmetric design. Roll faster with more comfort and more security on your next Gravel or XC ride with the Crest MK4 rim.

Technology

Stan's BST-Asymmetric Technology

BST-Asymmetric rims combine Stan's patented Bead Socket Technology--the original and still most reliable tubeless-ready rim design--with an asymmetric shape that allows for offset spokes, creating a stronger overall wheel. Most asymmetric rims struggle to inflate easily and maintain a reliable seal on both sides of the rim, but Stan's BST-Asymmetric rims equalize tire retention and dent resistance on each side of the rim, allowing for easy inflation and total ride confidence under even the hardest cornering.

Stan's BST Asymmetric rims feature distinct spoke hole offsets based on rim width. At 25mm wide, Crest MK4 rims have 1.5mm of spoke offset. The 28mm Arch MK4 rims use an offset of 2.5mm. The 30mm wide Flow MK4 rims use a 3mm offset. This level of precision optimizes spoke tension balance and allows for the strongest and most effective tubeless rim shape. The Crest MK4 asymmetric rim, for instance, has a near perfect 92% balance between drive side and non-drive side spoke tension, versus the 58% spoke tension balance of previous symmetric Crest MK3 rims. When used with M-pulse or E-sync hubs, Stan's MK4 BST-Asymmetric allows a single spoke length to be used for all matching sets. Whether you choose a MK4 wheelset with M-pulse hub or S2 wheelset with E-sync hub, a complete set of Stan's Crest, Arch, or Flow wheels will each use only a single common and readily available spoke length that works front or rear, either drive side or non-drive side, making maintenance and service easier than ever.

Stan's No Tubes WideRight Rim Design

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. Our WideRight rim widths are designed to strike the perfect balance between tire volume and sidewall function.

The Lightbulb.

Too narrow. Tire is constricted, robbing traction and cornering stability.

The Bell.

Too wide. Tire beads are pushed wide, deforming intended tire shape and tread design. Tire has less ability to absorb impacts and less cornering control, and sidewalls are exposed to cuts.

WideRight.

The perfect width. Tire expands to full volume without distortion. Tread pattern and side knobs are in the correct position for cornering, maximum traction and control with minimum rolling resistance.

WideRight rim profiles allow the tire to achieve its proper shape, and that's the foundation for a great handling, fast-rolling, and responsive bike.

Stan's WideRight system makes it easy to find the perfect rim width for the tire size and volume you ride. Too narrow of an internal rim mixed with a high sidewall design gives you a "light bulb" tire profile while an ultra wide rim on a narrower tire will give you a flat to "bell shaped" tire profile. Neither of these scenarios give optimal tire profiles nor allows the tire to perform as intended.

WideRight profiles provide the optimal volume without distorting the tread pattern or the side knobs so each part of the tire is in the correct position for rolling and cornering, allowing for maximum traction and control as well as offering minimal rolling resistance. The WideRight profile advantages don't stop there. Proper tire profiles not only allow for optimal tire performance but also allow the tire to do its secondary job of protecting the rim as well as the tire's sidewall. A flat or bell-shaped tire profile leaves the tire exposed to sidewall cuts and creates undue chances for rim damage.

Key benefits:

Optimises tire profiles
Maximizes traction
Properly distributes tire volume
Promotes the design intent of the tire profile and overall tire performance
Reduces tire pinch flats and sidewall damage
Allows tire to protect rim
