Tyres

- Panaracer GravelKing ZX is a semi-slick gravel tyre for fast mixed-surface use with a three-zone tread pattern for speed and lateral support.  
- New ZSG gravel rubber compound, TuffTex puncture protection and BeadLock technology are designed to ensure durability, grip and easy tubeless mounting.  
- Available in 700c, 35-55 mm, three variants (ZX, ZX+, ZX R), € 59.99-74.99, staggered market launch from March to October 2026.

- 32-inch wheels are set to usher in a paradigm shift in the gravel and MTB sector with better riding characteristics.  
- Maxxis offers a complete 32" tyre range from fast gravel and XC models to tread tyres for MTBs with more suspension travel.  
- Theoretical advantages: better rollover behaviour, higher rolling efficiency, more stability, larger contact area and less fatiguing riding.

- Continental is expanding the Dubnital with a 50 mm version that bridges the gap between MTB and gravel and is aimed at technical gravel races.  
- First practical test: easy to fit (tubeless), rolls quickly and comfortably, measured width 48.5 mm, weight 575 g per tyre.  
- The tyre is available as a race and trail casing with rapid compound, tubeless ready and hookless compatible, price: 74.95 euros.

- Lower tyre pressure and wider tyres increase comfort, traction and often efficiency on real, uneven road surfaces.  
- Optimum pressure depends on tyre width, system weight, inner rim width, surface, tubeless setup and discipline (road, gravel, MTB).  
- Professionals today, for example, ride 28-32 mm road tyres with approx. 4-6 bar, gravel approx. 2-3 bar, MTB approx. 1.4-1.7 bar depending on the discipline.

The right tyre pressure for road, gravel and mountain bikes: Air out!

- TPU tubes are very light, have a small pack size, low rolling resistance and high puncture resistance, but cost considerably more than butyl.  
- The material requires precise assembly and high manufacturing quality; errors or tolerances can lead to deformation, bursting or sudden loss of air.  
- Despite good laboratory values, practical use shows susceptibility to dirt and inexplicable air loss; more suitable as a lightweight replacement inner tube.

- Clik Valve replaces filigree grub screws with a click connection, makes inflation easier, but can only be used to a limited extent with SV pump heads
- Conversion is possible at low cost with many SV/DV, some AV and tubeless valves, TPU tubes with plastic shafts are not compatible
- Advantages: more robust handling and faster inflation; disadvantages: fiddly deflation, sometimes measurement problems, hardly any airflow gain compared to Presta

- Before the start of the season, check tyres for grit and check tubes and valves for cracks, fit and mobility.  
- For tubeless tyres, completely remove old, thickened sealant and valve residue; do not mix fresh sealant with other brands.  
- Check wheels for bearing play, concentricity and spoke tension; if unsure, leave centring work to a specialist workshop; tubeless offers more performance, tubing more simplicity.

- Kernloses Kugelventil im Schrader-Format maximiert den Luftdurchsatz und erleichtert das Befüllen mit Dichtmilch durch breite Öffnung.  
- Test zeigt: Nach 5 Sekunden ist mit dem Muc-Off Big Bore im 29x2,4-Reifen kein messbarer Druck mehr vorhanden, Bestwert im Vergleich.  
- Ventil ist schwerer (ca. 9,9 g), passt in Presta-Bohrungen, benötigt Schrader-Pumpenkopf und wird mit Montage-Tool und verschiedenen Dichtgummis geliefert.

- Pirellis P ZERO Race TLR SL-R spart laut Hersteller mit PAAS-Technologie im Seitenwind Ø 5 Watt, unter Bedingungen bis zu 15 Watt und 10 % Rollwiderstand.  
- PAAS formt Übergang Reifen/Felge neu, nutzt Segeleffekt bei Seitenwind besser, kombiniert mit spezieller Laufflächenstruktur für Aerodynamik und Grip.  
- Tubeless-Ready-Reifen mit LiteCORE-Karkasse und SmartEVO²-Mischung, kompatibel mit 22–25-mm-Felgen, in 28, 30, später 32 mm, Produktion in Italien.

- High-Flow-Tubeless-Ventile bieten verbesserten Luftfluss, einfachere Montage und sind weniger anfällig für Verstopfungen im Vergleich zu Presta-Ventilen.
- Muc-Off Big Bore und Reserve Fillmore Ventile zeigen im Test den besten Luftdurchsatz und verhindern effektiv das Verstopfen durch Dichtmilch.
- Ventile mit Standard-Presta-Kern bieten keine signifikanten Vorteile beim Luftfluss und sind weiterhin anfällig für Verstopfungen durch Dichtmilch.

Revolution in tubeless valves: More air, less clogging - the test

- Fillmore valve with continuous pin offers up to three times the air flow, facilitates tubeless assembly and reduces clogging from sealant.
- Valve closes the valve base via a tightly screwed dust cap, allows fine pressure regulation, but becomes virtually unusable if the cap is lost.
- Weight 5.55 g, price € 40, three lengths (50/70/90 mm), Presta-compatible, insert-compatible, lifetime guarantee, very high measured air loss (87.4 %).

Test Reserve Fillmore tubeless valves: an end to clogged valves

- According to the manufacturer, Holeshot Fast Flow valves offer 200 % higher air flow, facilitate assembly and filling with sealing milk without removing the valve core.  
- The internal, protected seal, anti-clog design, complete serviceability and lifetime guarantee are designed to minimise blockages and defects.  
- 11 g/pair, three lengths, twelve colours, Presta-compatible with additional functions in the valve caps, price 41.99 euros, considered a lightweight high-flow option.
