   RIM TECH ICONS   

TCS 2.0
 NEW  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.
TCS Tape
TCS TAPE
Light, strong, and extra sticky for durable, long-lasting, leak-resistant performance.
Solid Strip
 NEW  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
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
TCS TAPE
Light, strong, and extra sticky for durable, long-lasting, leak-resistant performance.
Drop Zone
 NEW  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 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 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 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 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 I-BEAM
The I-Beam adds strength to the inner rim cavity. This distinctive support counteracts spoke loads and provides lateral rigidity.
On Ramp 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 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 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 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
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
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 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
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.
