Custom Cannondale SuperX Gravel Bike – A Performance Art Build
Custom bike builder Den Seleznov created a one-of-a-kind Cannondale SuperX in a fully custom colorway. We’re proud to be part of this project with Ere Research components: the GENUS CT carbon saddle and Tenaci GA40 Gravel Aero wheels with custom-made decals.

Some builds go beyond performance — they tell a story. This SuperX is a showcase of craftsmanship, engineering and pure attention to detail. The final result is a true rolling artwork, built from the finest materials, with every choice supporting both speed and aesthetics.
This project also demonstrates what’s possible when experience meets premium components: a bike that’s ready to race, built to endure, and designed to inspire.
Technical Deep-Dive: Performance Behind the Art
While the visuals are striking, the engineering is what makes this build truly special. Below is a closer look at the Ere Research components used on this project and why they matter on modern gravel terrain.
Tenaci GA40 Gravel Aero Wheelset
The Tenaci GA40 wheelset was developed to combine aerodynamic efficiency with real-world gravel stability. The rim uses an aero profile shaped to reduce drag at gravel speeds while keeping handling predictable on mixed surfaces.

- Aero rim profile: designed for reduced drag without compromising stability
- Gravel-focused handling: predictable control on fast, rough terrain
- Custom decals: made specifically for this wheelset and custom build

Hub Technology: 36T Ratchet System
The hubs use a 36T ratchet system — a proven design known for fast engagement, efficiency under load and long-term reliability. It’s a system that has been trusted at the highest level of cycling for years.
- Fast engagement for technical sections and accelerations
- Proven durability under high torque and harsh conditions
- Efficient power transfer when it matters most

GENUS CT Carbon Saddle
The GENUS CT is built for riders who want a refined balance of low weight, support and comfort for long gravel efforts. On rough terrain, comfort equals speed — especially over hours in the saddle.
- Carbon construction for low weight and efficient support
- Ergonomic shape tuned for long-distance gravel riding
- Clean integration for premium custom builds
Why Aero Matters in Modern Gravel Racing
Gravel racing has evolved: courses are faster, groups are stronger and speed is sustained for longer. Aerodynamics can provide meaningful efficiency gains — especially when paired with stable handling and robust hub internals. This is exactly the balance the Tenaci GA40 aims to deliver.
