Description
Specifications

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.

Innovative & Differentiating Features

- Dual-valve system for fine-tuned grip and support adjustments

- Bead-lock design prevents burping and rim impacts

- Facilitates lower tire pressures for improved traction and rolling efficiency

- Adds minimal weight (+90g per wheel) compared to traditional foam inserts

- Compatible with 27.5" wheels, 28-40mm internal width rims, and up to 50psi inflation pressure

Optimize your mountain bike or gravel rig with the OPTIS Tubeless Tire Insert, and experience unmatched support, grip, and confidence on every ride.

  • Lightweight and Durable Materials with an Aluminum Presta Valve designed for optimal performance and longevity, ensuring reliable inflation and easy maintenance.
  • Advanced Dual-Valve Technology allows separate tuning of tire grip and support, enabling lower pressures for enhanced traction without sacrificing support or ride quality.
  • Innovative Odyssey Pneumatic Tire Insert System (OPTIS) effectively transforms your tubeless setup into a two-chamber system, improving grip, reducing rolling resistance, and providing impact protection through a bead-locking design.
