When you're looking for a lightweight Gravel and XC wheelset built to roll fast and last forever, the aluminum Crest MK4 is your wheelset. "Crest" is the name Stan gave one of his original rim designs, and today it belongs to one of the most advanced rims made. Built of 6069 alloy and featuring a reinforced spoke bed and welded seam, the 25mm wide Crest MK4 rim is made to handle both the higher pressures of 40mm gravel tires, as well as the lower pressures of 2.3" mountain bike tires.

The asymmetric design of the Crest MK4 rim improves spoke angle to create a stronger wheel, while still offering the ,easiest to inflate and most reliable airtight tubeless seal found only on Stan's patented Bead Socket Technology rims. Built for people who ride, by people who ride, the Crest MK4 wheelset relies on the proven strength of traditional J-bend spokes. As part of Stan's commitment to make easily serviceable wheels a rider can own for many years, all MK4 series wheels that are the same diameter share a single, very common, spoke length. Front and rear and both sides all use a single length, making replacing damaged spokes as easy as possible.

Available with Shimano Micro Spline, HG, or SRAM XDR freehub, and 6-bolt or Centerlock brake style, with options to fit all popular axle configurations.Tubeless ready with rim tape installed. With a lightweight asymmetric tubeless rim laced to one of the most reliable and fastest-rolling hubs made, the Crest MK4 sets the bar for Gravel and XC wheelsets.
