Despite being wider than previous models, the Crest MK3 and Flow MK3 rims are now even lighter. The Arch MK3, which sees the greatest increase in width, was kept at nearly the same weight as the previous Arch EX rim. The 6069 alloy and a rim shape that increases lateral stiffness for improved handling. Tubeless setup and maintenance remain as easy as ever.
One of the earliest advocates for the stability of wider rims, Stan’s NoTubes believes the pendulum has officially swung too far. “The shape of the tire on the rim is so important,” says company President and Chief Engineer, Mike Bush, “and a lot of rims out there are too wide to work with the tires we’re all using. Stretching a tire beyond its intended shape causes problems when leaning into corners and forces you to run higher air pressures to keep impacts from damaging the rim or pinch flatting the tire.” Stan’s WideRight concept was developed to find the optimal rim width for the most common tire sizes. “It took a lot of testing,” says Bush, “but our new rims offer the best balance between stability and tire shape.”
Even lower profile, the new Crest MK3 adds 2mm of internal width while dropping weight for faster acceleration and climbing, making it an excellent choice for lightweight, tubeless cross country performance. The new Crest MK3’s constantly tapering rim shape is engineered to be stronger while increasing tire volume for less rolling resistance and more stability.
Like all Stan’s NoTubes ZTR wheelsets, the Crest MK3 features patented Bead Socket Technology (BST). Refined over the past 15 years and proven with countless cross country and endurance wins, BST continues to be the standard by which all tubeless systems are judged.
Crest MK3 rims will be offered in 24inch, 26inch, 27.5inch, and 29inch sizes and in both 28hole and 32hole drilling. MSRP of the rim is $100. Wheelsets will be offered in a wide variety of axle configurations, including Boost and Cannondale Lefty, with an MSRP of $679. A SRAM Predictive Steering option will also be available for $825 MSRP.
The new Arch MK3 has seen the most drastic evolution. Mean, but still lean, the Arch MK3 is 24% wider, with virtually no weight increase from its predecessor. Based on input from our Enduro World Series teams, Stan’s NoTubes pushed the Arch MK3’s internal rim width out to 26mm for maximum tire stability and volume while keeping the rim itself incredibly light (only 425g for the 27.5” rim).
With a lower rim profile and stronger 6069 alloy, the Arch MK3 also sees a 25% increase in lateral stiffness for improved tracking and cornering precision. Featuring Bead Socket Technology, the new Arch MK3 also offers the tubeless traction, control and reliability only found on genuine Stan’s NoTubes rims.
MSRP for the Arch MK3 rim is $100, and rims will be offered in 26inch, 27.5inch, and 29inch sizes. Both 28hole and 32hole drilling options are available. Wheelsets will be offered in a wide variety of axle configurations, including Boost and Cannondale Lefty, with an MSRP of $679. A SRAM Predictive Steering option will also be available for $825 MSRP.
With proven success on the Downhill World Cup circuit, the legendary Flow was one of the most capable trail and all-mountain rims ever made. The new Flow MK3 goes bigger and better in every way.
Nearly 4mm wider, the Flow MK3’s 29mm internal rim width offers the perfect balance of tire sidewall stability and volume for tires up to 2.8” wide. A more durable 6069series alloy and lower profile rim also make this the toughest Flow ever made.
But stronger doesn’t mean heavier. Optimized rim shape and a stronger alloy also let the Flow MK3 weigh in 30g less than even the narrower Flow EX.
Born and bred for control at speed and on technical trails, the new Flow MK3 also features patented Bead Socket Technology, for easy tubeless setup and maximum reliability.
Flow MK3 rims will be offered in 26inch, 27.5inch, and 29inch sizes with 32hole drilling and an MSRP of $100. Wheelsets will be offered in a wide variety of axle configurations and an MSRP of $679.
The new rims and wheelsets will start arriving from July onwards. Initial supply will be limited as Stan’s NoTubes increase their stock levels in the USA.
Pricing will be similar to current versions but Rand / Dollar fluctuations will play a bigger part.
