Stan's lightweight aluminum valve stems are half the weight of Stan's standard brass valves. The secure round base is compatible with most tubeless rims and a perfect fit for all Stan's BST rims. A removable valve core makes adding sealant easy, and these babies fit up to 8mm valve hole. Sold as a pair.

Use Stan's Tubeless Valve Stems when you're converting standard rims to tubeless via the taping method. These also have a removable core for easier application of tire sealant. Note: Schrader valve is for non-stepped Hugo rims. If your Hugo rim decal reads: - MAX RIM PRESSURE: 2.8 tires: 26psi, 3.0 tires: 24psi - ERD 615, 622x49.9, 29 in x 52.3mm Your rim has a stepped valve and is not compatible with this Schrader valve.

Wheels are the first point of contact between you and your bike, and the trail you’re riding on. And while wheel sizes and standards continue to develop significantly year on year, often to both the rider and the industry’s dismay, very little innovation has been seen in the compliancy and responsiveness of the wheel as this first, most important contact and conductor. What Spank has seen in recent years is that bike suspension is continuously evolving and adapting to compensate for stiffer frames and more rigid, deeper profile carbon fiber rims. This overall stiffer rig is being softened, or counter-acted by both bike suspension, and tire design — not to mention the ever lower and lower tire pressures riders are running. Rider position (wider, lower, more forward) is also being impacted directly by the bike frame and cockpit geometries which is constantly aiming for a better riding feel. So surely it is overdue time to re-examine how the engineering of the wheel can become an active contributor to the efficiency of the overall set up. Spank Industries has done just this. - Low sectional profile height and wide width, adds radial compliance, while keeping high lateral stiffness. - 30mm internal width extremely versatile, fitting tires from 2.0” to 2.6” perfectly, and even allowing + size tire use, without negative squaring off of tire profiles. - Ideal for Trail/AM/Enduro bikes looking for a wide profile, without the weight penalty

- The most versatile, bombproof, all-purpose rim - 32 holes with an inner width of 26.5mm and outer width of 32mm - The corrugated rim center adds exceptional strength, making it more rigid and allowing the rim to be wider without adding material - Shot-peened finish increases fatigue life and durability - Delivers exceptional strength and stiffness at a remarkable value

The definition of "road cycling" now includes gravel and dirt as well as pavement. At the same time, bikes are evolving to meet the fit requirements of smaller riders. Meeting these two distinct needs was the driving force behind the Zipp 303 Firecrest 650B Tubeless Disc-brake wheelset. The smaller rim size provides room within frames and forks for larger tires that deliver increased comfort, compliance, and cornering performance. With more tire between the rim and the ground, the overall wheel diameter, including the tire, is similar to a standard 700c wheel and road tire combination. Back on the pavement, the 650B is a better-fitting wheel for smaller athletes riding compatible frames. For too long, many smaller cyclists have trained and raced on standard 700c wheels, losing out on the advantages of a proper fitting wheel such as improved handling and the elimination of front wheel-toe overlap. At the center of the 303 650B Firecrest Tubeless is a versatile and durable hubset, the German-engineered ZR1 DB. - Zipp graphics and cosmetic identity that scream speed - Versatile 45mm rim profile for increased speed and better cornering, control, and comfort - Tubeless design provides secure performance when ridden at lower tire pressures - ZR1 DB hubset is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Built with Sapim CX Sprint J-bend spokes - Center Lock rotor interface (lockring included) - Ships with 12mm end caps

Zipp's 303 Firecrest Tubeless wheels are designed for the real world—a world of imperfect conditions, varying road surfaces, and elements where the bottom line is simple: efficiency = speed. They're faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp's drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced wind resistance, rolling resistance, rider fatigue, and weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 32mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. At the center of the 303 Firecrest Tubeless is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless wheels are for dedicated cyclists who aspire to the latest in technology. They're for those who compete in races, against peers, or simply to conquer personal limits. - New Zipp graphics and cosmetic identity that scream speed - Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile - Lighter weight than its predecessor, making it nimble and fast - Tubeless Made Easy, optimized tire bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tire. - Ultra-wide 25mm rim profile creates a better tire interface to be fast on or off the road - 40mm rim depth makes a light and aero wheel in every situation - Ships with 12mm end caps - Center Lock rotor interface (lockring included)
