30+ years immersed in cycling and human performance. Built for riders who value experience, craft, and curiosity in pursuit of meaningful connection to the ride itself.
Sales & Service
We carry a deliberately limited selection of frames, components, and accessories chosen for one reason: they meaningfully improve the riding experience. Every product on our shelves has earned its place through real-world use, thoughtful design, and long-term reliability.
Bike Fit & Performance Testing
With more than two decades in bike fit and human performance, our process goes far beyond common rider positioning practices. Through detailed movement assessment and performance analysis, we identify root causes of persistent discomfort and complex fit problems other approaches often miss.
Precision Tools
Precision matters. When the industry fails to deliver the accuracy we demand, we design and manufacture our own tools—purpose-built instruments that raise the standard for measurement, alignment, and repeatable results.
The name Red Eye comes from a simple truth most endurance athletes recognize instantly: a hard effort leaves a mark.
Long climbs, sustained tempo, and those quiet moments where you choose not to quit often end with that unmistakable look—red eyes, a little hollowed out, and completely alive. It has nothing to do with how fast you are, what place you finish, or whether you ever pin on a number. It’s the product of an honest effort, and the satisfaction that comes with doing something difficult on purpose.
Precision Tools
Our patented Stem Alignment System, Stack & Reach System, and Knee Trackers resolve critical mechanical and fit challenges that we believe should be a part of every bike fit and service workflow.
Our patented Stem Alignment Tool solves a fundamental problem in modern bicycle setup. Universally compatible with contemporary frames, it references the fork and frame dropouts to deliver precise, repeatable stem alignment. Designed, engineered, manufactured, and assembled in Colorado, USA.
Compatible with and included:
9mm x 100 (QR)
12×100 Thru-Axle
15×110 Thru Axle
Optional:
Cannondale Lefty (+ $40)
Our bespoke Knee Trackers project a vertical laser reference to provide immediate clarity on frontal-plane knee motion throughout the pedal cycle. By creating a shared visual cue, fitters and riders can evaluate movement together—clearly and objectively.
Designed, engineered, manufactured, and assembled in Colorado, USA. Built for extended run times and rechargeable via USB-C. Purchase includes 2 laser line pods and a mounting stand for floor or fitting station use.
The system can also be used to help quantify Q-factor and Stance Width parameters of crank and pedal systems during fit sessions.
Kit includes:
(x2) USB-C rechargeable laser bodies
(x1) Laser body mounting apparatus
System does not come with USB-C charging cables…the world has plenty.
Our laser-based Stack & Reach System quickly identifies and measures the vertical (stack) and horizontal (reach) relationships of a bicycle’s critical touch points—including crank center, saddle, handlebar, and hoods or grips. Universally compatible with virtually any bicycle, it allows measurements to be documented and repeated accurately across bikes, sessions, and seasons. Designed, engineered, manufactured, and assembled in Colorado, USA.
Includes:
Mounting Apparatus
Saddle Height Jig
Saddle Angle Jig
Crank adapters - Sram 8mm & 10mm, Shimano Road & MTN, Easton Cinch, EE Wings
Laser pod mounts
Optional:
