The ZTR Arch EX Wheelset has been a favorite of trail riders who want versatility, strength, and low weight for everything from XC race to Enduro level terrain. The Stan's NoTubes tubeless system is tried and tested. The Arch EX rim is perfect for general trail use because it is both light and strong, without being too wide for narrower XC tires. The rim shape is the same is used in the more XC-oriented Crest, but NoTubes adds in the internal arch found in the wider, freeride Flow. This gives the rim exceptional inherent strength in a 29er at just 460 grams. Stan's rims employ bead socket technology. BST marks a huge step forward in tubeless technology, allowing for lighter rims, lower sidewall heights, improved durability, increased traction, and decreased chances of pinch flatting.

Seating Tubeless Ready tires on a BST rim is about as easy as it gets. BST rims allow the bead to properly lock into the rim for the best quality airtight seal. The bead/rim interaction is superior even with an inner tube. The low-profile shape of BST rims makes them lighter for less rotational mass for weight saving where it matters most. BST allows the tire to expand to full size so you can run lower pressure with less pinch flats and your tire functions more efficiently for better cornering, traction and reduced rolling resistance.

The advanced 32 hole NEO hubset was designed as NoTubes saw new standards like Boost coming. The 3.30 series hubs were very good, but the Neo series makes big upgrades, answers the weaknesses, and is more flexible of future changes. Featuring 100% precision CNC machined hubshells, a wide stance bearing system in the freehub, integrated high durometer seals, and oversized swaged axles, the NEO is a new animal. Wider spaced and oversized chrome steel bearings are used all-around, and in the rear, the 4-pawl, 10 degree, 36-point engagement system is a big upgrade from the 3.30, especially when riding technical terrain at slower speeds. The engagement is still simultaneous and incredibly reliable. The hub flanges of the machined shell are now angled to improve spoke alignment and ease more consistent spoke tension. Construction and performance reflect reliability and durability, perfect for heavy use, and ideal for future-proof standard updates.

NoTubes is using Sapim Force steel j-bend spokes. The Force are both strong and incredibly resilient to impact. Butted at 2.0/1.7/1.8mm, the tapered steel offers just enough give to limit rim damage from big impacts despite high spoke tension. Sapim Secure Lock nipples hold the 3x lacing tight, and prevent any wind-up from disc brake stopping power, even with 180mm rotors. Of course you get your rims pre-taped with Stan's NoTubes tubeless rim tape, and the valves you need to make tubeless happen. The rear Neo hub comes with either Shimano or SRAM XD Driver options, and is convertible. with the appropriate NoTubes kit. If you are riding or building a thru-axle standard frameset, and either want a stock upgrade, or just desire the tubeless ease of NoTubes wheels, the ZTR Arch EX Wheelset is ready to tackle the trail underneath you.
