Optis Tubeless Tire Insert – 27.5″ x 28-40mm Insert w/ Standard Presta Valve

Description

Enhance your mountain biking and gravel riding performance with the OPTIS Tubeless Tire Insert – 27.5″ x 28-40mm Insert with Standard Presta Valve. Engineered for serious riders seeking top-tier grip, support, and durability, this innovative tubeless tire insert offers a revolutionary approach to bike handling and efficiency.

Materials & Construction

Crafted from high-quality nylon and thermoplastic polyurethane (TPU), the OPTIS insert combines lightweight strength with superior flexibility. The aluminum Presta valve ensures reliable inflation and deflation, while its yellow finish adds a vibrant, professional touch to your wheelset.

Performance & Engineering

The OPTIS system introduces a dual-chamber, two-valve design that separates grip from suspension, allowing riders to independently tune tire support and traction. Inflating the insert to a higher pressure than the tire creates a bead lock that prevents burping and rim impacts, effectively enhancing ride stability and protecting rims from common impacts.

Components & Technology

Featuring a removable valve core for easy maintenance, the OPTIS insert is optimized for rims with internal widths of 28-40mm and maximum valve hole thickness of 18mm (0.70 ). Its lightweight design adds less than 90 grams per wheel, significantly reducing rotational inertia for faster acceleration and more responsive handling. The dual-valve setup enables lower tire pressures, reducing rolling resistance on rough terrain and improving grip without sacrificing support.

Style & Use Case

Designed for aggressive trail riding, enduro, and gravel adventures, the OPTIS Tire Insert is your go-to upgrade for enhanced traction, impact protection, and ride confidence. Its compact form factor and durable materials make it ideal for riders demanding performance and reliability on challenging terrains.
