Make your WTB rims air tight and ready for tubeless use with WTB's TCS Rim Tape. This tape covers the spoke holes and can be used as a lightweight rim tape in any rim. Available in 11-meter (covers 5 rims) and 55-meter rolls (covers 27 rims).

Surly Rim Strips have one job and they do it well. They cover the cutouts in your rim and — if you're running a tube — they protect it from spoke heads and other sharp matter (okay, so maybe they have TWO jobs but they do them both really well.) Rim strips are crucial and should be used with all Surly rims. Ours come in an array of colors so you can really "express yourself." Surly Rim strips are available in two different materials: PVC and Nylon. PVC is great if you plan on only running tubes. However, if there's any part of you that wants to try this tubeless thing you've been hearing about, Nylon strips are just the ticket. They're thinner and offer minimal stretch so they stay put and lay nicely inside the rim to provide a secure seal. Plus, they're lighter which we all know means you'll go faster… maybe.

Performance Upgrade Made Easy The C38 brings carbon fiber high performance to the real world. It's a versatile all-rounder equally at home crushing gravel washboards and summiting alpine passes. Optimized for use with modern wide tires, providing the right amount of sidewall support to facilitate surefooted handling in all conditions, the C38 wheelset is a great handling, lively climbing, robust all-road performer that also aerodynamically outperforms many deeper, aero-specific rims that cost twice as much. Carbon wheels are a true performance upgrade to any bike, but too often the price tag puts them out of reach. The Rapide C38 shatters that barrier and brings a class-leading Roval carbon rim and DT Swiss reliability together to provide riders with the best performance carbon wheel per dollar.

Taking the notion of combining flagship performance with workhorse dependability one step further, we're introducing the Terra C. This shares the same hub and spoke architecture as the Terra CL, ensuring ease of service and spoke replacement, should the need arise and is paired with an entirely new rim layup. The rims on the Terra C share the same dimensions and broad range of tire mounting possibilities as the Terra CLX and CL—33mm deep with a 25mm internal width—but are crafted using a new-to-us process known as Resin Transfer Molding. This is an automated process that allows us to very precisely control how resin is introduced to the layup, which in turn ensures maximum strength and material performance. The end result is an incredibly tough set of wheels that you can beat on to hell and back. - Rim: Terra C RTM Carbon Clincher, 700c, Disc Brake, Tubeless Compatible - Rim Details: 32mm Depth, 30mm External Width, 25mm Internal Width; ERD 577mm - Hub: DT Swiss 370 J-bend Center Lock, Ratchet LN 18t internals (20 degs), 100x12mm & 142x12mm, Shim.

Road bikes are going where they’ve never gone before, are expected to do more, and are being ridden harder than ever. At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With a disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever. Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance, even when ridden at lower tire pressures. A new carbon fiber layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while SRAM's robust 77/177D hubset keep the wheels stiff and responsive. Each Wheel Includes: - Zipp Tubeless valve extender and valve-core wrench - Zipp rim tape (factory taped) - Zipp Tangente quick-release skewer - Zipp thru-axle 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)
