TCS TESTIMONIALS

"It's hard to find ways to take weight off your bike while still adding performance and durability. TCS tire and wheel systems do just that without making your bike an anchor."

- Mark Weir

 

"After the staff at WTB helped me out and walked me through it, I can change a TCS tire quicker than I can change a tube."

- Bobby McMullen

 

"One year we took 30 media guys riding. Thirty flats later I swore I would never take anyone riding with tubes again. Last year, we set the same number of bikes up with TCS wheels and tires, and had only one flat. The difference is huge."

- Jason Moeschler

TIRE TECHNOLOGY

 

WTB was founded by and is controlled by people who care about riding mountain bikes.  Tire passion runs deep and is a matter that is beyond personal to us, we’re downright particular about our treads.  From our Ground Control tire designed for Specialized in 1985 to our 2013 Nine Line tire co-developed with Cannondale and input from our global race team, there’re a lot of tires in between.

WTB is responsible for the first 29” tire, the NanoRaptor 2.1 in 1999 and this tire is symbolic of the independence, ingenuity, and unadulterated creativity that go into each of our tread patterns today. 29” bicycles were the shameful dunces of a time period where wheel size could not be questioned.  The overwhelming popularity of this wheel size today in the global marketplace only gives credence to WTB’s unflinching spirit of innovation.

WTB’s tire future heads fearlessly forward with aid of 3d modeling, industrial design standards, and direct feedback from racers and customers.  Our wholehearted approach to Enduro racing has resulted in square-edged, open-tread patterns proven in the Alps and Dolomites.  New casings retaining compliance yet yielding impervious protection have resulted in a new understanding of what tires are capable of.  Tuned rebound characteristics and optimized durometer compounds are resulting in tires that allow our athletes and riders to push the sport further.

 

TIRE TECHNOLOGY DEFINED

DNA RUBBER COMPOUND

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

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.

GRAVITY DNA

45a durometer, glue-like conforming rubber covers a supportive 60 durometer base creating uncanny traction with tuned rebound characteristics designed to take harsh hits yet not fumble for footing.

DISTANCE COMPOUND

Found in WTB and Freedom’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.

TCS (TUBELESS COMPATIBLE SYSTEM)

Tubeless Compatible System: Standards-driven system designed around tubeless bead shapes and hooks to create repeated sealant-based consistency between tire and rim.

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.

LIGHTWEIGHT CASING

A supple, gram-conscious carcass designed to be compliant and conform to trail objects while still providing a happy balance of low rotational weight and rugged reliability.

ENDURO CASING

Take our proven Lightweight Casing found in TCS Light tires and… well… double it. Yep, Enduro 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.

BEAD

Folding beads are lighter than conventional steel beads and easier to install. Steel beads are more economical and better suited for aggressive, trail riding applications.

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

WTB recommends that tire pressure be checked before each ride. The acceptable pressure range for tubed mountain bike tires is 35- to 65-psi (2.4- to 4.5-bar). Road tires must be inflated to 100 to 130-psi (7- to 9-bar). TCS tires must be inflated between 30 and 50 psi (2- to 3.5-bar). City/Trekking/Hybrid tires must be inflated between 50- and 80-psi (3.5- to 5.5-bar). Tire pressure outside of these guidelines can result in a loss of control or, at the very least, poor performance.

TPI

TPI stands for threads per inch. This number 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 Race and TCS tires offer supple, shock absorption qualities while remaining resistant to cuts and tears.

SADDLE TECHNOLOGY

Bike saddles are very personal objects.  Ask several cyclists of their favorite models and you will receive very different responses—even if the riders are similar in size and skill level. In the next few pages you’ll find a range of seats designed for varying physiques, riding styles and shape preferences.  With over 30 thoroughly-researched, rider-tested models, WTB offers the ideal perch for everyone from world champion racers to their grandmothers.  No matter what your age, gender or ability level, we’re guessing that you’re not a fan of numbness or pain in your nether regions.  Because we care about your comfort, you’ll find several key anatomically-friendly features that span the entire WTB saddle line.  These proprietary designs place more support on your ischial bones (“sit bones”) and less weight on sensitive soft tissue.  As a rule, WTB saddles are flatter in profile than others.  Our profile supports your sit bones and relieves pressure from sensitive areas, whereas rounder saddles pull the pelvic girdle apart, placing pressure where you don’t want it.

 

SADDLE TECHNOLOGY DEFINED

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.

LUXZONE

This comfort-enhancing window is featured exclusively on the Valcon saddle.  Similar to our proprietary Comfort Zone soft tissue relief area, Lux Zone reduces pressure on sensitive soft tissue.

DNA PADDING

Found on all of our high-end models, this dense padding dramatically reduces the weight of the saddle.  DNA padding also features superior memory properties, which conforms to your individual anatomy.

SOFT-SHELL

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

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, Flex-Tuned saddles provide the happy medium that is ideal for most enthusiasts.

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.  This base is found on our top-level Silverado, Valcon, Devo, and Deva, .

ABR CORNERS

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

TITANIUM RAILS

Titanium rails offer an unparalleled strength-to-weight ratio as well as superior vibration damping characteristics.

NICRO TUBULAR RAILS

NiCro is a hollow alloy rail material that is close to as light as titanium, but available at a more economical cost. 

CARBON RAILS

Carbon rails offer the lightest weight option with extraordinary shock absorbing characteristics.  Found on our top shelf Valcon and Silverado saddles.

RIM TECHNOLOGY

We have spent a lot of time figuring out how to effectively make things tubeless.  Our All Mountain racing heritage at places like Downieville first gave birth to frustrations over inadequate, makeshift tubeless means available, then provided a demanding testing ground for honing in bead and rim interfaces, casing thicknesses, and optimized durometer combinations.  It is where TCS, our Tubeless Compatible System, went from an idea to a proven reality.

Square-shaped bead hooks, UST specified bead bumps, and a tape and sealant driven system have created rims that adhere to universal specifications, yet bask in feathery light weights.  Our proven I-beam, cutting edge 4D drilling, and a mind-numbing amalgamation of WT69 Alloy are just a few of the features that make our rims unique.  Our Frequency rims are a testament to what can be done with these technologies.

While a lot of our passion and product development man hours are put towards the competitive tubeless arena, we provide great options for tube type usage and rim brakes.  With a long history of rim production, there’s a rim for everyone in our line and we implore you to find the rim that will change your ride.
 

RIM TECHNOLOGY DEFINED

TCS

The tubeless compatible TCS rim profile is especially designed for TCS or UST tires and is also compatible with tube type tires when used with tubes.

I-BEAM

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

4D DRILLING

Our spoke holes are drilled at the precise departure angle to align spoke head and nipple with 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.

WT69 ALLOY

WT69 Alloy has a 20% higher yield than 6000 series Aluminum alloy and is so strong that it can be extruded into lighter rims that are tougher and stiffer than their heavier competition.

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.

ISO/ETRTO COMPLIANT

For use with tube-type tire and inner tube.

DISC ONLY

Compatible with disc brakes only.

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 and LaserDisc rims.

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.

DOUBLE WALL

Carefully selected rim wall thickness along with a “Box” section allows for a strong, yet light rim.

PINNED

6mm pins, oversized for stiffness and strength.

SLEEVED

Increased strength, decreased weight.

GBS (GLOBAL BEAD SYSTEM)

WTB’s proprietary GBS (Global Bead System) design utilizes deeper grooves for the bead seats as well as two raised lips that lock the tire’s beads into place on the rim. GBS, found on LaserDisc and SpeedDisc series rims, features superior tire retention and greatly reduces the chance of ”burping” the tire off the rim in heavy lateral loading.

SIDEWALL INDICATOR

A groove in the braking surface that when no longer visible, indicates that the rim needs to be replaced due to sidewall braking wear (due to cantilever brake pads).

DUAL DUTY

Compatible with disc brakes and v-brakes.

All WTB Rims are Crotchet-Type. When inflation pressures over 72 psi / (5-bar) are used, appropriate rim base protective flap must be fitted. Crotchet-Type Rims can be used with rigid and foldable bead tires. In case of Tubeless application with a Tubeless or TCS Tire, a special air tight tape must be used with WTB Rims, or a special UST Rim must be fitted to the bicycle. Visit WTB.com for a more detailed explanation.

GRIP TECHNOLOGY


GRIP TECHNOLOGY DEFINED

CLAMP-ON TECHNOLOGY

Another WTB innovation, Clamp-On grips bolt securely to the handlebar via two alloy clamps. Unlike the average lock-on type grip that uses a thick, plastic base, Clamp-On technology utilizes a minimal nylon skeleton. Because there is no layer of dense plastic between your hands and your handlebar, Clamp-On technology is slimmer in profile, more comfortable and lighter weight than lock-ons.

DUAL CLAMP-ON

Forget the windex, hairspray, or whatever else you used to mount your grips. Our new 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 bothbenefitfromdualcompoundrubber.Theoutsidelayer of the grip is an easy-on-the-hands soft rubber, while the firm Kraton base material resists twisting and slipping.
