A Go-Anywhere Trail Helmet with Updated WaveCel Technology

The Trek Quantum WaveCel is a lightweight mountain bike helmet designed for trail riding across varied conditions - a ride-anything helmet that delivers WaveCel safety technology and everyday comfort at a value-focused price point in Trek's MTB helmet range. The Large size in black is a versatile, clean finish suited to any kit combination.

The Quantum uses the same updated WaveCel generation as the Rally and Blaze - lighter and cooler than previous WaveCel versions, with 10% larger cells that improve airflow through the liner for better temperature management during climbs and trail sessions. The new extended coverage provides greater protection than the prior generation Quantum - expanding the protective zone for improved safety without adding the weight or reduction in ventilation that extended coverage can sometimes impose.

WaveCel is Bontrager and Trek's proprietary collapsible cellular structure that responds to impacts through a three-phase flex, crumple, and glide sequence - managing both direct and rotational impact forces more effectively across a wider range of impact types than standard EPS foam alone. CPSC certification confirms compliance with the US safety standard.

Extended Coverage, Headmaster III Fit System, and Lay-Flat Straps

The extended coverage on this generation Quantum provides greater protection at the rear and sides of the head than the previous version - a meaningful safety upgrade for trail and all-mountain riding where the full range of impact directions is a realistic consideration. Strategic vents with recessed channeling manage airflow through the extended coverage shell without the ventilation sacrifice that more coverage can create.

The Headmaster III Fit System provides simple and secure one-handed retention adjustment - a dial-based system that tightens and loosens the helmet's fit ring while wearing the helmet, allowing fine adjustment without removing the helmet or stopping the ride. Headmaster III is a more accessible fit system than the BOA system found on the Rally and Blaze, delivering the core functionality of one-handed adjustability at the Quantum's price point.

Lay-flat camlock straps reduce the twisting and binding that standard strap hardware creates under the ears and along the cheek - the flat camlock design keeping the straps flush and comfortable throughout the ride without requiring adjustment after every session.

Three-Position Visor with Sunglasses Storage

The three-position adjustable visor can be set to accommodate different light conditions, goggle use, and rider preference - moving to three distinct positions for flexibility across varied riding situations. Dedicated sunglass storage on the helmet provides a secure location for sunglasses when switched to different eyewear or when light conditions change during a ride.

FAQs

How does the Quantum WaveCel differ from the Rally WaveCel?

Both use the same updated WaveCel technology and share the lay-flat camlock strap design. The Rally uses the BOA Fit System and Fidlock magnetic buckle for higher-end fit precision, and includes a Blendr mount for cameras and lights. The Quantum uses the Headmaster III Fit System - a more accessible one-handed adjustment system - at a lower price point without the Fidlock buckle or Blendr mount. Choose the Rally for more premium fit features; choose the Quantum for updated WaveCel protection and comfort at a more accessible price.

What is the Headmaster III Fit System?

Headmaster III is Trek's dial-based retention system that provides one-handed fit adjustment while wearing the helmet - tightening or loosening the fit ring with a single turn without stopping or removing the helmet.

What does the updated WaveCel technology provide on the Quantum?

The Quantum uses the latest WaveCel generation with 10% larger cells than previous versions, improving airflow through the liner for a lighter and cooler feel. WaveCel's three-phase flex, crumple, and glide response manages both direct and rotational impact forces across the helmet's coverage area.

Does the Quantum WaveCel have a Blendr mount for a camera or lights?

No. The Blendr magnetic mount system is a feature of the Rally and Blaze WaveCel helmets. The Quantum does not include a Blendr mount.

What coverage improvement does the new Quantum provide over the previous generation?

The new Quantum has extended coverage providing greater protection at the rear and sides of the head than the prior generation - expanding the protected area for improved safety on trail and all-mountain riding.
