The radial technology of Schwalbe is consolidated with an expansion in models and sizes
In line with the new restructuring of the Schwalbe range for MTB, it takes a new step by expanding its presence of radial models within the catalog. What started as an experimental solution within its laboratory is now consolidated as one of the brand's most important technological lines, with more models and versions available.
Schwalbe expands its range of radial tires and strengthens its commitment to this technology in MTB
The expansion of Schwalbe Radial tires is not just about numbers. It also brings adjustments in constructions, new sizes, and a clear reorganization of some key models within the gravity and e-MTB range.
What really changes with radial construction
The basis of this evolution lies in the tire's own structure. While in a conventional tire the threads of the casing are arranged diagonally at an angle close to 45 degrees, in radial construction that angle opens up significantly.

This change in internal arrangement has direct consequences on performance, with a larger contact area with the ground at the same pressure, increased grip, better absorption capacity, and more control in demanding situations.
Schwalbe quantifies this increase in contact at around 30 percent, which explains why this technology is clearly oriented towards aggressive or technical use.
More models adopt radial technology
Until now, radial construction was limited to specific models, but with this update, it is extended to a good part of the range.
The tires that incorporate new radial versions are:
- Romy
- Tacky Chan
- Eddy Current
- Magic Mary
- Albert
This move confirms that the brand does not see it as a one-off alternative, but as a long-term development line within MTB.
The Schwalbe Tacky Chan grows and replaces the Big Betty
One of the most relevant changes within this expansion affects the Tacky Chan, which gains prominence within the gravity range.
A new version in 2.5 inches is introduced, which is offered exclusively with radial construction. In this variant, Schwalbe has modified the tread design with a 2-2 arrangement that aims for more predictable handling, cleaner transitions in corners, and a clear improvement in braking.
Additionally, the Tacky Chan takes the place left by the Big Betty, which disappears from the catalog. The model is available in both radial and classic construction versions, with Trail, Gravity, and Race options.
Regarding prices, a dual strategy is maintained:
- Standard versions between €44.90 and €49.90
- Pro versions between €69.90 and €74.90, reaching up to €79.90 in radial
Eddy Current simplifies its range and focuses on rear use
The Eddy Current also changes its focus. This model, clearly oriented towards e-MTB, eliminates the differentiation between front and rear tires.
From now on, only the rear version is maintained, which becomes the only one available and adopts radial construction in Gravity Pro configuration.
It is offered in 27.5 and 29 inches, with a Soft compound and a slightly reduced width of 64 mm. The price is set at €79.90.
Magic Mary adds radial versions and new options
One of the brand's most iconic models also evolves. The Magic Mary expands its offer with new versions that incorporate radial casing, available in 27.5 and 29 inches.
These versions maintain the same level of side protection and performance but introduce a cleaner sidewall finish. Additionally, the model adopts the new Ultra Soft compound in certain configurations.
At the same time, Schwalbe strengthens its positioning in the mid-range with classic construction versions at more affordable prices, between €44.90 and €49.90.
Albert and Romy consolidate the radial line
The Albert, Schwalbe's first radial tire, expands its offer with new size combinations and versions, reinforcing its role within this technology.
For its part, the newly presented Romy integrates directly into this expansion, also available with radial construction and positioning itself as a more versatile option within the catalog.
With this expansion, Schwalbe makes it clear that radial construction is no longer an experimental solution or exclusive to specific models. It becomes a central piece within its MTB strategy.
