Notubes Crest MK4

If you're looking for a lightweight gravel and XC wheelset that rolls quickly and lasts forever, then the Crest MK4 wheelset made from aluminum is your choice.

The 25 mm wide Crest MK4 rim, made from a 6069 alloy with a reinforced spoke bed and welded seams, is suitable for the higher pressure of 40 mm gravel tires as well as the lower pressure of 2.3" mountain bike tires. The asymmetric design of the Crest MK4 rim improves the spoke angle to create a more stable wheel.

The M-Pulse hub combines the best materials and construction with a smart engagement system, designed to roll smoothly for longer. The core of the M-Pulse hub is its magnetic locking system, based on the innovative Project321 design and produced in a high-precision small-batch manufacturing process. The M-Pulse freehub features six pawls equipped with neodymium magnets that engage with more force every 1.66° compared to traditional spring-based pawl designs, offering less resistance when coasting. With reduced friction and resistance, Stan's NoTubes provides a 5-year warranty on this compelling and durable technology!
