C/DURO EPONA
The everyday do-it-all trail bike
Simple, sophisticated single pivot suspension, lightweight design, and perfect do-it-all trail capability define the EPONA. Advanced materials and technology, combined with clever single pivot and progressive geometry, make it a versatile trail bike that is agile in corners and calm when the trail gets rough. You can smash corners on flow trails, shred in bikeparks, send jumps, and even challenge yourself on downhill tracks and enduro races.
EPONA is built around a single pivot suspension with 150 mm of travel, tuned for effective pedaling (As ~105%+) especially when climbing, solid performance under braking (Ar ~90%), and low pedal kickback (6° at 32/10 gear). With 8% progressivity, it’s designed for an air shock, making it as simple and sophisticated as it is capable for every ride.
When designing the geometry, we focused on giving riders the freedom to choose size based on riding style, not just height. All sizes feature a low standover height and shorter seat tubes to fit the longest dropper posts on the market. This means even smaller riders who want extra stability and confidence can comfortably size up.
NOT JUST ANY CARBON FIBER
All C/DURO frames are made in an automated process from advanced carbon fibres UMS40 and M40J with very high stiffness (~400GPa) and strength (~4500MPa), resulting in a very stiff, strong and lightweight frame. The stiffness gives our bikes distinctively precise and agile ride feel without harshness thanks to vibration damping capabilities of our tubes. A very high stiffness to weight ratio puts the natural frequency of C/DURO frames higher to avoid resonance and loss of grip.
CONFIDENT
Combination of high stiffness and aggressive geometry give the EPONA distinctive ride feel that will boost your confidence.
LIGHTWEIGHT
Thanks to precision of automated fiber placement and single pivot suspension, frame weights only 2.2kg w/o shock.
RELIABLE
On each side, there is a pair of 61903 stainless steel bearings, that were selected with sufficient reserve to last you longer.
ADJUSTABLE
The oversized head tube is compatible with ZS56/ZS56 angle headsets, giving you the freedom to fine-tune your bike’s geometry to match your riding style.
UDH COMPATIBLE
The frame is compatible with UDH and Transmission standards.

The right frame size depends on your riding style. If you want more stability and support from the bike, choose a larger size. If you prefer agility and a more playful feel, a smaller size may suit you better.
Geometry may vary depending on the frame size, fork rake/offset, and wheel choice.

The Epona grabs your senses the moment you start pedaling – it just moves effortlessly. Climbing feels almost like riding an XC bike. But when the trail points down, it’s a whole different story: the frame is stiff yet compliant, letting you feel the terrain without harsh impacts. The result is a lively, fun ride with no energy lost between you and the trail. And maybe the best part? Despite all the advanced materials and tech behind it, it stays utterly simple – one pivot, four bearings, and that’s it. Just ride and forget the fuss of servicing or washing. This bike just works.
