Mountain Bike Folding Outer Tyre with 180 TPI Casing for Off-Road and Trail Cycling

This mountain bike outer tyre is presented as a component suitable for travel, training, and off-road cycling. Its core specification includes a high-density 180 TPI (threads per inch) casing, which in tyre construction typically refers to a measure of the casing fabric's threads per square inch, often associated with a balance of weight, suppleness, and puncture resistance. The tyre carries a maximum atmospheric pressure rating of 120 psi, indicating its capacity for higher inflation pressures which can affect rolling resistance and ride feel. It is constructed with a three-layer hierarchy, a common build method for mountain bike tyres that combines different rubber compounds and reinforcement layers. The product is distinctly offered in two primary bead types: a folding bead variant and a steel wire bead variant, catering to different user preferences for installation ease and rim compatibility.

Features and Construction

The tyre's build is defined by several key measurable specifications from the source text. The 180 TPI rating denotes the casing density, while the three-layer hierarchy points to a multi-ply construction. The maximum load is stated as 100, though the specific unit of measurement (e.g., kilograms) is not provided, so this should be considered a relative rating within the product's own range.

Material and Build

The primary material detail provided is the 180 TPI high-density casing. The construction is described as having a three-layer hierarchy. The bead is available in two material types: a folding bead, typically made from a flexible aramid (Kevlar) material, and a traditional steel wire bead. The choice affects the tyre's packability and the effort required for fitting. The sidewall colours are offered in either yellow or white, providing a visual differentiation.

Size and Practical Fit

The tyre is available across the standard modern mountain bike wheel diameters: 26 inches, 27.5 inches (650B), and 29 inches. Within these diameters, specific widths are offered, including 2.0 inches and 2.2 inches. It is crucial to note that not every size is available in both bead types; for example, the 27.5x2.2 size is listed for folding bead tyres in white and yellow, but for steel wire bead, only a white 27.5x2.2 is listed. Potential buyers must cross-reference their required size with the exact style (bead type and colour) option available.

Uses and Placement

The product information explicitly lists its intended uses as travel, training, and off-road cycling. This positions it as a general-purpose mountain bike tyre rather than one specialised for a single discipline like downhill or cross-country racing.

Event or Professional Use

For training and off-road cycling, the 120 psi maximum pressure and load rating suggest a tyre capable of handling varied terrain and pressures appropriate for skill development and recreational trail riding. The availability of wider (2.2-inch) options provides more traction and volume for challenging conditions.

Everyday Home Use

As a tyre suitable for travel, its folding bead variants would be easier to transport as spares or for trips where bikes are packed. The range of sizes ensures compatibility with many older (26-inch) and newer (27.5-inch, 29-inch) mountain bikes commonly used for commuting on rough paths, light trail riding, or general fitness cycling.

Benefits and Buying Value

The value of this tyre lies in its clear specification for key performance metrics and the breadth of size and build options, allowing riders to select a precise match for their bike and riding style.

Reuse and Low Maintenance

The three-layer construction and 180 TPI casing are practical features aimed at providing a serviceable lifespan under the stresses of off-road use. The stated maximum load and pressure ratings give users parameters to operate within for sustained use. Choosing the correct bead type for your rims can also simplify future changes or repairs.

Why Choose This Product

This tyre offers a defined set of specifications—180 TPI, 120 psi max pressure, three-layer build—across a wide array of modern mountain bike sizes. The option between folding and wire beads allows selection based on whether ease of fitting and transport or a traditional secure fit is a priority. The explicit sizing (e.g., 27.5x2.2) and colour (yellow/white) options provide clarity for buyers matching a replacement or upgrade.
