Radke™ performance eyewear with Fenom™ lenses is part of Wildhorn's debut into MTB accessories. Each pair comes with three lenses to allow for the best possible experience in any condition. One exception is the photochromic models which are equipped with a single lens that adjust automatically to light based on exposure. If you are looking for durable, performance-oriented eyewear optimized for fun in the Mountains, radke™ is a perfect choice.


  • Fenom™ light management system
  • Maintain visual clarity in any light condition
  • Complete UV400 protection (UVA/UVB)
  • Compatible with all Radke frames
  • Anti-scratch lens coating
  • Non-polarized to optimize for trail riding

Photochromic Benefits

Photochromic lenses are designed to adjust to variable light conditions automatically. The lens will lighten or darken depending on how much light is available. These lenses are non polarized. The Smoke variation has the largest range of VLT between 15%-85%. The Blue variation range is 39%-84%. Each provide a nice range of tint. The Blue lens is a cooler tint while Smoke is warmer.

Tech Specs

  • Lens: Polycarbonate
  • Tint: Photochromic variable
  • CE certified (EN ISO 12312-1:2013+A1:2015 Eye and face protection)


To change out lenses, remove the bottom half of frame by pulling one edge until it pops out from the top piece. Then pull from the middle to release the nose bridge, and finish by pulling the opposite end. Carefully remove the lens by pulling from one of the sides first. Clip the new lens in starting from the one of the sides. Make sure you hear an audible click from each side and the middle. Once the new lens is in place, clip the bottom frame back in or use the replacement nose bridge for a half frame setup.

A great pair of cycling performance eyewear does two things: protection from harmful sunlight and optimizes visual performance. Fenom™ is Wildhorn's newest eyewear platform that provides light management, optical clarity, and peripheral vision. When you ride it's important to maximize visibility, light filtration, and color. Fenom™ lenses on Radke™ are interchangeable to allow greater freedom on the timing of your rides.


The visual light transmission rating, or VLT, determines how much tint is in your lens. For bright, sunny days you'll want a lower VLT option to block out most of the light. A medium VLT works best for cloudy or mixed days (or riding in and out of treelines). A high VLT works best when riding in the darkest conditions. Most Radke™ models come with a high, medium, and low VLT lens. Photochromic models are equipped with one lens which automatically adjusts its tint based on light conditions. The Radke™ eyewear platform offers you a variety of options that cater both to preferred light experiences and style.


Down hill light spectrum management requires greater focus on greens and browns to optimize your visual trail experience. With a careful balance of blue, green and red light, a more true color spectrum improves a rider's experience. True color, rather than high contrast, creates the best trail riding experience in biking.


Radke™ was designed and tested near the base of the Wasatch mountains near SLC, UT. With a world class trail system just minutes away from our HQ, we spent hours testing Radke™ prototypes until we got it just right. We also tested with local riders and took community input to continually improve the design. We're a proud local brand with grass roots in the iconic Utah outdoors scene. We don't release anything we wouldn't buy ourselves!

Looking for lower cost - found great quality

Wanted to get in without spending $200. After 10 rides, these glasses are excellent. The fit is good, there is no slip with the nose piece, and the 3 lenses are perfectly aligned for the various lighting conditions. Definitely recommend.


I need to return sent wrong lens

I am so sorry you received the wrong lens. Though it is rare when these things happen, we do address it with the warehouses we work with. If you need any assistance from our team, with your exchange, please don't hesitate to contact us at


Photocromic capabilities are weak. Almost no shade over when exposed to sunlight. Might as well just buy clear lenses.
Lenses also would not fit in the frames. Temple slots were loose and the nose slots did not line up with the grooves.
Complete waste of money.

I wouldn’t have purchased these if I knew they already came with the glasses.
