Stans - Rim Crest MK4 24 32h Black

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 Stans trademark unmatched airtight seal. The Crest MK4 rim is optimised for 40mm Gravel tyres and up to 2.3 mountain tyres, making it a great, versatile choice for a wide range of bikes and riding styles.

The durable but forgiving ride of the Crest MK4s 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, its built for speed.

The Crest MK4 combines the heritage of Stans legendary tubeless design with todays 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.

• 25mm rim width optimised for Gravel and XC tyres up to 2.3
• Light and durable 6069 aluminium with welded joint and reinforced spoke bed
• BST-Asymmetric design combines Stans legendary easy tubeless inflation with a stronger, more balanced wheel build
• 3-year rim Warranty with 1-year crash replacement

BST-ASYMMETRIC TECHNOLOGY (BST-A)
BST-Asymmetric combines the benefits of Stan's BST with more balanced spoke tension to create a stronger wheel.

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 tyre 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.

WIDERIGHT
Balancing rim width and tyre width leads to faster cornering and improved control.

The most important piece to the bicycle-terrain interaction is the contact patch between the tyre and terrain, so tyre profile and tyre pressure play huge roles in bicycle performance and overall handling. But many rims just don't work well with the tyres we're all using.

Rims that are too narrow fail to offer sufficient sidewall support and protection to your tyres 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 tyre profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tyre's volume. Our WideRight rim widths are designed to strike the perfect balance between tyre volume and sidewall function.

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