26 Inch Mountain Bike Tyre Specification: Identify More Than the Diameter
A 26 inch mountain bike tyre specification becomes more useful when its model and compound stay with the dimensions. The US woom OFF AIR 6 page names Schwalbe Rocket Ron in 26 × 2.35 inches with ADDIX SPEED rubber compound. A shopping note containing only “26-inch tyre” loses most of that identity.
26 inch mountain bike tyre specification: keep the named version
Write Schwalbe, Rocket Ron, 26 × 2.35 inches and ADDIX SPEED together. The manufacturer supplies a brand, model, dimensional description and compound name. A different Rocket Ron version or another tyre sharing the diameter should not silently be presented as the published original equipment.
The source describes low rolling resistance, grip and durability as product qualities. Those are manufacturer descriptions, not measured results from this article. The compound’s name also does not establish an inflation pressure for a particular rider or a tested grip result on a specific surface.

Add the wheel setup without confusing its parts
The tyre section lists Presta valves and says tubeless conversion ready. Presta describes the valve arrangement in that equipment record; it should not be interpreted as a valve built into the tyre casing itself. Conversion readiness is another description, not confirmation of what is installed inside an offered bicycle’s tyres.
For identification, take a clear record of the markings actually fitted and keep it beside the factory description. If those markings differ, ask which version was supplied. woom’s product-variations notice acknowledges that supply-chain changes can lead to differences between the page and the received bicycle.
The listing identifies woom OFF AIR 6 - Kids’ bike - 26 inches - 10 – 14 Years - terra coppa. Its one wheel-size selection is not a compatibility table for every tyre sold under a twenty-six-inch label. The cited specification does not publish an ETRTO marking, complete rim dimensions or an alternative tyre approval, so none is reconstructed here.
The purpose is a precise original-equipment comparison: which model, dimensional label, compound and setup description are being discussed? A later purchase or conversion needs its own applicable instructions. The photograph is historical family context and cannot identify the exact present tyre, valve or sealing arrangement of the bicycle being offered.
FAQ
Which compound name is printed?
The US tyre entry names ADDIX SPEED.
Is Presta the name of a tyre compound?
No. It describes the valve arrangement, while ADDIX SPEED names the compound.
Does this confirm a delivered tubeless installation?
No. Readiness wording does not document the actual completed setup.
