Take our proven Lightweight Casing found in TCS Light tires and... well... double it. Yep, Tough Casing is composed of two full layers of casing, leaving no area unprotected on our TCS Tough tires. Developed through real world testing during the Enduro World Series, this casing is designed to take punishment and has been optimized for sealant usage, retention, and consistency.

ROAD TCS CASING

The road-going sibling of our TCS Light casing. Tubeless simplicity paired with unbelievable suppleness in all the sizes you want for surfaces ranging from smooth tarmac to hardpack dirt or gravel.

URBAN ARMOR CASING

Urban Armor Casing provides additional rubber throughout the entire casing and sidewall to deliver additional puncture protection while also ensuring it holds up to cornering on asphalt and even the occasional curb rub.

DURABLE CASING

A robust and substantial casing provides the strength needed for our wire bead tires to last. A high ratio of rubber to thread protects against trail threats and urban unpleasantries. Found in all Comp level tires.

RACE CASING

Now called Tube Type Light, it is a lightweight casing paired to a folding aramid bead. This casing type is ideal for the rider using inner tubes but demanding high-end performance from their tires.

Compounds

NEW TRITEC COMPOUND

Three compounds provide optimal levels of traction, support and durability. A base of high durometer rubber supports the entire tread and transitions into the knobs to prevent folding or squirming. Medium stiffness center knobs cap the base layer to provide traction and durability without sacrificing rolling efficiency, while soft compound side knobs deliver maximum grip and slow rebound for increased cornering traction.

DUAL DNA RUBBER COMPOUND

Dual DNA is the perfect mix of efficiency, traction, and durability. The centerline tread features a firmer rubber compound that boasts faster rolling and increased durability, while the side knobs are composed of softer, slower-rebounding rubber that improves control and grip.

DNA RUBBER COMPOUND

Our proprietary 60A durometer rubber compound offers the ideal mix of rolling efficiency and traction for Cross-Country and trail riding applications. DNA rubber is renowned for being versatile and long-lasting.

GRAVITY DNA RUBBER COMPOUND

The 48A durometer, glue-like conforming rubber creates uncanny traction with tuned rebound characteristics designed to take harsh hits yet not fumble for footing.

DISTANCE RUBBER COMPOUND

Found in WTB’s pavement tires, this compound is specifically formulated to maximize the lifespan of tires. Sick of wearing out tires yet don’t care to ride on a pair of Crayons? Try our Distance Compound for a harmonious pairing of longevity and traction.

Terminology

TPI

TPI (threads per inch) refers to the thread count in a tire’s casing. A lower TPI indicates that thicker threads are woven into the casing, therefore making it more durable; a higher TPI indicates that thinner threads are used, therefore making the casing lighter and more pliable. WTB’s 60 TPI, TCS and Tube Type Light tires offer a supple casing with shock absorption qualities while remaining resistant to cuts and tears.

DUROMETER

The durometer of rubber refers to its hardness, which is rated according to its resistance to indentation. The lower the durometer rating, the softer the compound is. For example, a 42A compound will be softer than a 60A compound. Many TCS tubeless tires are made using multiple compounds with different durometer ratings.

SIPING

Sipes are small incisions on a tire’s tread. Siping a knob creates more working edges, which boosts traction in virtually any condition. Because WTB’s high-end mountain bike tires feature shallow sipes, the knobs stay firm under heavy loads and hard braking.

TIRE PRESSURE

The amount of air pumped into a tire affects its traction and ride characteristics. Too much pressure will result in a rough ride and lack of traction. Too little pressure will result in a squirmy ride and potentially unsafe bead retention that may not hold the tire on the rim while cornering. All WTB tires have recommended tire pressures indicated on the sidewall.

ARAMID BEAD

The area of the tire where it contacts the rim is called the bead. Tires with aramid beads utilize high-strength kevlar fibers that are spun into the bead to provide ultimate durability while also being lightweight and foldable. All TCS tires have aramid beads.

WIRE BEAD

The area of the tire where it contacts the rim is called the bead. Tires with wire beads utilize a thin, woven wire throughout the length of the bead to provide strength and proper tire retention. Tires with a wire bead cannot be folded. Entry-level tires are often made with a wire bead to provide them at an affordable price.

GMS (GLOBAL MEASURING SYSTEM)

Our Global Measuring System provides two measurements, the casing width and the overall width of the tread. Both are described in millimeters, with casing width written first.


Saddle Technology

Accompanied by new graphics, WTB now offers a complete line of saddles covering a full range of widths and padding thicknesses. However, even the most comfortable saddles require a fitprocedure to ensure riders end up on their ideal saddle. The revolutionary WTB Fit Right System uses simple steps to guide riders towards the ideal saddle width and padding thickness that matches their physiology and riding position. Our goal is to provide riders with a saddle that fits so perfectly they forget it’s beneath them.

Technology

LOVE CHANNEL®

Found on all WTB saddles, the Love Channel has one very important task: protecting your body from unwanted pressure. The central depression provides soft-tissue relief without sacrificing the structural integrity of the saddle.

COMFORT ZONE®

Featured exclusively on high-end WTB saddles, these small windows are cut away from the base of the saddle to provide additional relief from pressure on sensitive areas. Comfort Zone is a subtle difference that provides impressive long-term comfort.

Padding

DNA PADDING

Found on all of our high-end saddles, this dense padding dramatically reduces the weight of the saddle. DNA padding also tends to hold its shape better over long rides and the lifetime of the saddle, which is important for long-term comfort.

STANDARD PADDING

Single density foam found on our Comp and Race level saddles. This foam is soft to the touch and is a great option for anyone experiencing sore contact points on their saddle.

GEL PADDING

Strategically placed gel inserts conform to the specific shape and width of a rider’s sit bones to provide a fit that is unique to the rider. The gel inserts are surrounded by our Standard Padding to provide additional padding that will not pinch or put pressure on soft tissues.

Rails

CARBON

Top-tier performance and ultimate weight savings for gram-conscious riders. These rails are designed to provide optimal support at a minimal weight.

TITANIUM

Nearly as light as carbon, titanium rails are able to flex without losing structural integrity, making it a great material for saddle rails.

CROMOLY

Increased strength and less weight make cromoly steel a noticeable upgrade over traditional steel rails. The perfect choice for bikepackers.

STEEL

Our entry-level saddles utilize strong and reliable steel rails to provide lasting comfort and durability at an affordable price.

Shells

NYLON / CARBON COMPOSITE SHELL

The WTB Composite shell consists of nylon or carbon fiber composite. It provides a firm and supportive feel for unparalleled performance and efficiency.

FLEX-TUNED SHELL

The Flex-Tuned shell boasts an exceptional mix of comfortable flex and firm efficiency. Not as supple as the Soft-Shell and not as stiff as the Carbon Composite Shell, Flex-Tuned saddles provide the happy medium that is ideal for most enthusiasts.

SOFT-SHELL

Shock-absorbing, dual-compound saddle base. Soft-Shell saddles minimize trail vibration while providing a rigid platform for efficient pedaling.

Materials

ABR CORNERS

These durable patches of material protect the corners and sides of the saddle from rips and tears.

MICROFIBER COVER

Found on most WTB saddles, our Microfiber cover closely replicates the look and feel of a leather cover. The supple nature of the Microfiber Cover allows the foam to support the sit bones without interfering with its resiliency.

SYNTHETIC COVER

Found on entry-level WTB saddles, our Synthetic Cover provides a thicker, more durable cover that is offered at a more affordable price.

Rim Tech Icons

TCS 2.0

TCS 2.0 creates a more robust, easily installed and dependable tubeless system. A recessed channel along the center of TCS 2.0 rims allows installation of the all-new Solid Strip, which prevents tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between the tire and rim. Installation of the Solid Strip allows for more pliable, and easy to install, Flex Tape to provide the airtight seal needed for a proper tubeless set-up.

SOLID STRIP

Narrower and more durable rim strip that sits in the rim bed to eliminate any possibility of a broken spoke puncturing the tubeless tape and causing the system to lose air. Solid Strip prevents tubeless tape from sagging at the spoke holes, which ensures a smooth surface between the tire and rim, prevents air from escaping during installation and makes it considerably easier to mount tubeless tires using only a floor pump. Installation of the Solid Strip allows for application of Flex Tape, which makes tubeless tape installation much easier.

TCS

Designed to meet UST and ETRTO Standards, TCS (Tubeless Compatible System) tires feature the best of both worlds: they boast the ride benefits of a tubeless tire with the minimal weight of a tube type tire. This versatile system combines WTB’s weight optimized casings, tread compound of your choice, and a tubeless, UST bead.

TCS Tape

Light, strong, and extra sticky for durable, long-lasting, leak-resistant performance.

DROPZONE

Designed to make tire removal easier, the Dropzone is a downward slope from the bead seat to the center of the rim, which allows the tire bead to quickly and easily fall into the optimal area for tire removal. Dropzone is only found on rims that have an inner rim width of 40-45mm.

ISO/ETRTO COMPLIANT

Internationally standardized tire bead and rim sizing. This ensures that the fit and relationship between a rim and a tire are as secure and user-friendly as possible.

CID (COMPATIBLE INTEGRATED DESIGN)

Each part within the system works with others available in the industry. If you need a new part, chances are it’s already in stock at your local bike shop.

4D DRILLING

Our spoke holes are drilled at precise departure angle to align the spoke head and nipple with the hub flange, eliminating binding and lateral loading while also dispersing the load more evenly over a greater area. This prolongs the wheel’s lifespan and increases stability.

DOUBLE WALL

Two separate layers of rim material provide increased structural strength while also preventing any contact between spoke nipples and the rim strip/tape which could lead to an unreliable tubeless set-up.

I-BEAM

The I-Beam adds strength to the inner rim cavity. This distinctive support counteracts spoke loads and provides lateral rigidity.

ON-RAMP

An angled inner rim profile that allows the bead of the tire to move easily and smoothly into place during installation and inflation.

SLEEVED

Rim ends are joined together using an extruded aluminum insert that matches the inner cavity of the rim. Both ends of the rim are hydraulically pressed over the tight tolerances of the insert and then further reinforced by industrial epoxy.

PINNED

Rim ends are joined together using steel pins that press into cavities located directly beneath the bead seat area. Both ends of the rim are hydraulically pressed over the tight tolerances of the pins and then further reinforced by industrial epoxy.

UNBENDIUM BULGE

By adding a thin rib of aluminum to the outer hips of the rim, we’ve added measurable strength and stiffness to counter torsional and axial loads. This WTB innovation is found exclusively on Frequency rims.

ASYM

Asym rims use an asymmetrical design to create a rim that more evenly distributes spoke tension, resulting in an easier to build, stronger, and more reliable wheel.

DISC ONLY

Disc Only rims benefit from lighter weights because they do not require the amount of material traditional rims require for the braking surface. Do not use Disc Only rims with rim brake systems, such as cantilever or v-brake.

SIDEWALL INDICATOR

Grooved braking surface that indicates when the rim needs to be replaced due to sidewall wear from the use of rim brakes. It’s time to replace the rim once the braking surface wears even with the bottom of the groove.

TUBE TYPE

Tube Type rims are designed to be used with inner tubes. These rims utilize an ETRTO tube type bead shape that relies on tire retention through proper installation and inflation of a properly sized inner tube.


Grip Technology

We make a myriad of grips in dual clamp, single clamp, slip-on and PadLoc grips. Some have been around for 30 years, some are new the team. We are constantly trying to innovate a product that has been around the block a time or two.

Grip Levels

PADLOC®

PadLoc technology utilizes a rubberized wedge shape that increases comfort and control. The rubberized wedge integrates perfectly with a PadLoc handlebar to eliminate grip rotation and provide the ultimate level of grip comfort.

PadLoc Overview and Cutting Guide

DUAL CLAMP-ON

Forget the windex, hairspray, or whatever else you used to mount your grips. Our dual aluminum clamp system facilitates easy grip installation while keeping the grip lightweight. Save the hairspray for looking good.

DUAL COMPOUND RUBBER

The Dual Compound Trail grip and the WeirWolf Trail grip both benefit from dual compound rubber. The outside layer of the grip is an easy-on-the-hands soft rubber, while the firm Kraton base material resists twisting and slipping.
