Product Information

Two rubber compounds. The centerline tread features a firmer rubber compound that rolls fast and resists tread wear while the side knobs are composed of softer, slower-rebounding rubber to improve control and grip. Narrower rims will cause a tire to also have a narrower width, with less air volume within the tire, and a rounder tire tread profile than designed for. When installing tires on ASYMMETRICAL rims, it is helpful to always mount the tire onto the rim on the "short side" of the rim. By that, we mean the side of the rim with the shortest distance from the rim leg/bead to the valley of the rim where the valve sits. Loss of substantial tire pressure over a few days is likely indicative of ineffective/old tire sealant or air seeping through the tire sidewall. In these rare cases, we suggest removing the complete tire and wheel system from the bike, adding the proper amount of fresh sealant, then shaking the tire to ensure sealant has covered the entirety of the sidewall. Simply spinning the tire on the bike will only push the majority of the sealant more towards the tread region of the tire, where air loss is less common. Slightly firmer knobs hold their shape and don’t transfer their energy to the trail as much as softer knob does.

All of our alloy rims work great with a 34mm valve stem. If you are using a deeper dish rim, like our CZR i23 rim, then we recommend the 46mm long valve stem. CZR i30 rims accept either length of valve. Which width TCS Tape should I use for my rim? Make sure tire bead is sitting in the deepest part of the rim profile. This is often referred to as the “valley” of the rim. Wider rims will cause a tire to also have a wider width, with more air volume within the tire and a flatter tire tread profile than designed for. Single-ply 60 tpi casing. The tread is wrapped over a single layer of 60 tpi casing to create a gram-conscious level designed to be compliant and grippy, while also minimizing weight for cross-country and trail riding.

SmartForm C3 Alloy: Simple yet sophisticated aluminium construction yields a light, lively frame that outperforms anything in its class. Avoid using tire levers during installation. Doing so can damage the tubeless tape and prevent an airtight tubeless system.

TCS stands for Tubeless Compatible System, which has proven itself as the most reliable and robust tubeless system available. When we a design tire, we do so around a specific inner rim width that is most applicable and commonly used in conjunction with the tire width. This is also the combination in which we determine and name the width of the tire. However, that combination may not reflect the rim width you have on your bike or are now looking to upgrade your bike with. SAVE Micro-Suspension: Delivers a smoother, more controlled ride thanks to strategically engineered flex zones built into the frame's rear triangle.WTB recommends using tape that is 5mm wider than your inner rim width. Most of our rims will have the inner rim width listed in the name (i.e. Frequency i23 uses 28mm TCS Tape). Can your Road Plus or Mountain Plus tires fit in my frame? Although many aggressive riders, as well as those living in wet climates, prefer High Grip on the rear as well to provide ultimate traction in exchange for a bit more rolling resistance.
