Arch S2 wheelsets have the versatility to handle a wide range of riding conditions and are the ideal upgrade for Trail, AM, Enduro, and eBikes. When your average ride includes both tough climbs and rough descents and you want the best tubeless system in the business, the Arch S2 is for you.Versatile 28mm internal width optimised for 2.2-2.5 tyres6061 aluminium with sleeved joint and stainless steel rim eyeletsPatented BST low-profile rim shape for easy tubeless inflation and the most reliable sealMatched wheelsets use traditional J-bend lacing and share a single spoke length for easy serviceabilityE-sync hubs offer fast 8.18° engagement with reinforced pawlsEnduro bearings with double-row freehub bearing and cromoly axle offer 47% increase in max torque capacity over Neo hubsConnection program includes 3-year E-sync hub warranty, 3-year S2 rim warranty, 1-year crash replacement, and $10 donation to trail maintenance or advocacy group of your choiceStan s Patented Bead Socket Technology means easier tubeless inflation and more confidence on the trail. The 6061 aluminium Arch S2 rims use a reinforced spoke bed and eyeletted spoke holes for strength, along with a reliable sleeved joint that creates one very tough overall wheel. The 28mm width is extremely versatile, offering excellent cornering performance with 2.2-2.5 tyres.The Arch S2 rolls on E-sync hubs made specifically to handle abuse and the added forces of today s capable trail bikes and even heavier eBikes. E-sync hub durability is found in the pawl design that reduces stress on freehub and bearings, heavy duty cromoly steel axles and double row Enduro bearings, as well as the special heat treated steel ratchet rings. E-sync hubs are also designed for fast engagement, with four pawls needing only 8.18° of rotation to engage simultaneously and drive you forward. E-sync hubs are perfect for eBikes and riders who demand stronger components, but still want the fast engagement of a high-performance hub. S2 wheels are built to last long, but also be easy to service and update with changing axle and cassette standards. Traditional J-bend spokes and lacing have a proven history of ride quality, durability, and serviceability, and matched S2 wheelsets all use a single spoke length, making it easy to own and service your S2 wheelset for years.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 comes pre-installed. When you need a reliable wheelset that s more than capable on both the climbs and the descents, the Arch S2 is for you.What s included: Tubeless tape installed, requires additional valve stems.

Stans No Tubes Arch MK4 RimFeaturing a 28mm wide asymmetric rim shape and an ultra-strong 6069 alloy construction, this mountain bike (MTB) rim is built for strength and reliability to handle the demands of modern MTB riding. Mountain bikes have changed in the decade since the original Arch rim helped introduce the world to tubeless technology. Today's Arch MK4 rim has evolved to match these more capable bikes. Through all the years of testing and refinement of this rim, one thing has never changed: versatility. Now more than ever, when you want a reliable rim that can handle every trail, the Arch MK4 is for you.6069 Aluminium Alloy RimThe Arch MK4 rim is light enough to take XC racing but was born from research and testing on the Enduro World Series circuit, making it a great rim for anyone looking to improve both descending and climbing. Constructed of light and strong 6069 aluminium alloy, with a reinforced spoke bed and 28mm internal width ideal for 2.2-2.5″ tyres, the Arch MK4 can get you up the climbs easier and make the descent even better.Asymmetric ShapeThe Arch MK4's BST Asymmetric shape improves spoke angle, allowing for a stronger overall wheel build. Unlike most asymmetric rims that struggle with tubeless inflation and consistent airtight seal under hard cornering, the Arch MK4's shape is designed to equalize pressure for easy inflation and incredibly strong tyre retention on both sides of the rim.Patented Bead Socket TechnologyStan's patented Bead Socket Technology, combined with a stronger asymmetric design, light and durable 6069 alloy, and the perfect rim width for balancing control and weight, make the Arch MK4 your best choice for all-around riding.

Stans No Tubes Arch S1 Mountain Bike WheelsetThis versatile wheelset features a durable construction that has been designed to help you tackle the toughest of trails, it's also lightweight enough for cross-country races. The Arch S1 wheels provide you with enhanced grip and control when running 2.25’’ to 2.50’’ tyres.Tough ConstructionMade for maximum durability, they feature a 32-spoke count with easily replaceable standard spokes, 6061 alloy rims, and stainless steel rim eyelets. The Arch S1 wheelset also features Stan’s faster-engaging, CNC-machined Neo hubs. Wherever you ride the Arch S1 will be ready to handle it all.Features: Durable and lightweight aluminium construction Wider rim width for more stability with larger tyres 2mm wider and 16g lighter than Rapid 28 Rim profile optimised for 2.25”-2.50” tyres Rim Material: 6061 Alloy Rim Internal Width: 26.0mm Rim External Width: 29.7mm Rim Depth: 17.3mm ERD: 566mm (27.5") / 604mm (29") Spokes: Sapim 2.0/1.8/2.0mm ETRTO: 584x26 (27.5")/622x26 (29") Nipples: Secure Lock brass silver nipples ISO: 27.5"x29.7mm/29"x29.7mm Hub: Stan’s Neo Tape: 27mm Hole Count: 32H, 32H Valve: 35mm Presta compatible (valves sold separately) Max Spoke Tension: 125kgf (1225N) Max Rider Weight: 105kg (230lbs) Max Pressure with 2.20" Tyre: 39psi Max Pressure with 2.50" Tyre: 36psi Brakes: Disc Use: Trail and enduro Weight: 1,882g (27.5”)/1,974g (29”)Technologies: WideRight: Rims that are too narrow fail to offer sufficient sidewall support and protection to your tyres 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 tyre profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tyre's volume. Stan's WideRight rim widths are designed to strike the perfect balance between tyre volume and sidewall function. BST (Bead Socket Technology): Bead Socket Technology rims are designed to match the shape of your tyre's bead to create a safer and more secure airtight interface. BST rims secure the bead of the tyre, not the sidewall, creating an airtight seal while allowing the tyre's sidewall to expand to its true, rounder, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, Stan's BST rims are also lighter and stronger by design and accelerate more quickly. Neo Hub: The Stan's Neo hub has a 100% precision CNC machined hub shell that is both incredibly light and strong. It features a 4 pawl, 36-point drive system for amazingly quick engagement. Oversized bearings ensure maximum durability and the swaged axle & wide bearing stance is 3 times stronger than conventional designs. There is a high durometer main seal integrated into the hub shell and the Sealock end caps lock into place bringing unmatched smoothness.Buy Stan's No Tubes Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

The new Power Arc Expert saddle expands on the success of our original Power saddle. It features the same channel length and hollow titanium rails as the original and Pro Arc but where it differs is in its shell and padding. But this means that it still features a stiff composite shell and supple Level Two PU padding. The shape of the saddle is also designed to provide ample sit bone support and this has been coupled with a shorter-than-usual nose section to keep pressure off of soft tissue while riding in aggressive positions. We even took this ideology a step further via an extra wide and elongated Body Geometry channel that's been proven through blood flow testing and pressure mapping to reduce numbness and pressure on unwanted areas. And while this all seems familiar if you're already a Power loyalist this iteration features a curved Body Geometry shape that better contours to your body. What does this mean for your ride? It means that you'll feel as if you're “in the saddle'' not on it. And ultimately this equates to greater comfort and superior performance in all seated positions whether you're a man or woman. Patented Body Geometry design is lab-tested for both men and women to assure blood flow to sensitive arteries. Lightweight and supportive PU padding for comfort and support on longer rides. Lightweight durable and hollow titanium rails. Level 2 padding: Medium density foam for bike feel with additional cushioning.
