The Super Yummy, which was born for super-cyclists who practice "Bug Out!", has been renewed to be about 14% lighter than before. By determining the volume point of the side rubber that is necessary and sufficient, and adding an anti-puncture layer instead of the thin side rubber, we maintain puncture resistance. Aiming to create a tire that is both light and strong, we worked together with the Panaracer technical team to maximize overall lightness and suppleness while ensuring durability. An all-round off-road tire with a tread pattern that balances lightness and running power at a high level. Of course, it is compatible with tubeless. - Wheel Size: 26"(559) / 27.5"(584) / 29"(622) - Tire Width: 2.22" - Bead: Folding - Weight(Average): 678g(26") / 712g(27.5") / 768g(29") *For rim compatibility, please check the size compatibility table and be sure to use a rim whose size is within the compatible range. *Be especially cautious with tubeless specifications. Models with low sidewalls, such as tubeless rims, and rims with small hookless or bead hooks may not work.

Trying to choose between a knobby, semi-slick, or full slick for an upcoming ride or race? The Manastash Ridge handles everything from fast pavement to deep mud or snow. Named after a rugged ridge in central Washington, the Manastash Ridge uses our revolutionary dual-purpose knobby tread. Strategic placement of the knobs means the tire is always supported by the same amount of rubber, whether rolling forward or leaning into a turn. This gives you uniform grip at all times – whether in a muddy gravel race or during a paved descent with ultra-fast hairpin turns. Our new Brake Support technology ensures that the knobs don’t fold over, even under the massive g-forces generated by the best hydraulic discs. Noise canceling technology makes this knobby tire as quiet and smooth as a slick—even on pavement. No matter what the course throws at you, the Manastash Ridge has you covered. The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse. The Extralight casing takes the performance, comfort and feel of your bike to an entirely new level. The Endurance casing is reinforced for extra sidewall protection and puncture resistance, while retaining the speed and comfort for which Rene Herse tires are famous. The Endurance Plus casing provides the ultimate in sidewall protection for extremely tough conditions. The Manastash Ridge is tubeless-compatible. For tubeless setup, we recommend SealSmart sealant. When used with tubes, we recommend SV17 or SV18 tubes. Pro Tip: The noise cancellation improves further during the first 30 miles (50 km) as the sharp edges of the knobs wear off a little.
