STANS NO TUBES Crest MK4 29´´ 6B front wheel

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. A legendary rim deserves a legendary hub, and the Crest MK4´s M-pulse hubs deliver. Designed in partnership with Project321, and CNC machined in their Bend, Oregon shop, M-pulse freehubs use an innovative Neodymium magnetic pawl design that offers an incredibly positive and reliable engagement with virtually no drag. Unlike traditional pawl and spring designs that create unnecessary friction when not engaged, the magnetic pawls of the M-pulse hub are at their strongest when engaged while minimizing drag when disengaged. Multiple teeth on the pawls distribute load to increase strength and durability even more, while a full set of Enduro bearings and 7075 alloy 17mm axle allow the M-pulse to handle more than twice as much force as Stan´s previous hub designs. The shielded design of the M-pulse hubs also protects the bearings from direct exposure to the elements for even longer bearing life. But the real beauty of the M-pulse hubs is their low rolling resistance and engagement speed. An easily adjustable bearing preload feature makes it fast and simple to fine tune M-pulse hubs for reduced friction and less resistance. All this in a hub that engages with only1.66° of rotation for instant acceleration. 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.

The additional stress of larger cassette cogs, more capable bikes, and even more challenging trails led us to create the Neo with Durasync and Neo Ultimate with Speedsync. From its debut in 2015, the Neo has performed at the highest levels of racing in the most extreme conditions, but constant quality feedback from our teams helped us make it even better. Both Neo and Neo Ultimate now feature triple freehub bearings for increased axle stability to handle even greater vertical and torsional loads. The Neo Ultimate with Speedsync maintains the nearly instant 5-degree engagement of 6 pawls engaging three at a time. The Neo’s Durasync system engages all 6 pawls simultaneously for unrivaled durability M-pulse Hubs: - Combining the best materials and construction with a smarter engagement system, M-pulse hubs are built to roll smoother longer. The heart of M-pulse hubs is the magnetic locking engagement system based on the innovative Project321 design and manufactured in their small-batch, high-precision facility in Bend, Oregon. M-pulse freehubs feature six pawls equipped with Neodymium magnets engaging every 1.66° with more force than traditional spring-based pawl designs and less resistance when coasting. With less friction and drag, M-pulse Stan´s Notubes 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. 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 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. What´s Included: - Crest MK4 wheels include pre-installed tape for tubeless use and presta valves.
