e*thirteen Expands the Grappler Tire Platform, Adding a Radial Casing

e*thirteen has announced a significant expansion to its Grappler mountain bike tire line, introducing a new three-tier platform comprising the Grappler, Grappler RS, and Grappler TR models. This update also sees the integration of a radial casing option across the range, a design choice traditionally more common in automotive applications, aiming to enhance ride characteristics and durability for off-road cyclists.

This move by e*thirteen is particularly noteworthy given the increasingly competitive and specialized mountain bike tire market. Radial casings, while not entirely new to cycling, represent a departure from the ubiquitous bias-ply construction, promising improved compliance and potentially reduced rolling resistance. For a brand like e*thirteen, known for its gravity-oriented components, this innovation signals a strategic play to capture a broader segment of the trail and enduro market, offering riders more tailored options for specific terrains and riding styles.

Ultimately, e*thirteen's embrace of radial technology suggests a willingness to innovate where others merely iterate. Whether the market truly *needs* a radial mountain bike tire, however, remains to be seen.
