Swift UniVox Evo
The Swift UniVox Evo redefines what’s possible in an endurance road bike, delivering the ultimate combination of long-distance comfort and uncompromising performance. Designed for cyclists who demand versatility across varied terrain, the UniVox Evo merges ergonomic efficiency with cutting-edge racing technology, making it ideal for everything from epic gran fondos to all-day explorations on unpredictable roads.
At its heart lies a refined Endurance geometry, placing riders in a powerful yet comfortable position for sustained speed over hours in the saddle. Whether you’re pushing through a timed challenge or soaking up the scenery on remote countryside loops, the Swift UniVox Evo ensures comfort never comes at the expense of speed.
This Evo edition takes the platform to new heights, now featuring the precision of the Shimano Ultegra Di2 12-speed electronic groupset, matched with lightweight, durable DT Swiss Endurance ER 1600 wheels. Every component has been carefully chosen to enhance the ride: agile, responsive, and smooth, no matter the gradient or surface.
Swift UniVox High-Performance Carbon Frame
Crafted from premium TAIRYFIL TC36S carbon fiber, the UniVox Evo frame delivers an exceptional balance of minimal weight and maximum strength. The innovative design includes the Blind Dropout feature—an elegant solution that conceals thru-axle threads for a cleaner, more aerodynamic look. An integrated seat clamp adds to the sleek aesthetic, while functional elements like Flex seatstays actively absorb road buzz and micro-impacts for a noticeably smoother ride.
Despite its comfort-first geometry, the Swift UniVox Evo doesn’t sacrifice handling. With room for up to 40c tires and a lower center of gravity engineered into the chainstay design, the bike offers both nimble agility and rock-solid stability—perfect for those who like to push hard on technical descents or mixed-surface adventures.
Optimised for the Long Haul
The frame includes a total internal cable routing system and a PF30 BB86 EVO bottom bracket, contributing to both frame stiffness and low overall weight. The rear 12x142mm E-Thru axle further enhances power transfer and bike rigidity. For riders who go beyond the ordinary, the UniVox Evo also includes integrated mounting points for mudguards, saddle bags, and even a top tube bag, ensuring you’re ready for endurance rides and light touring setups alike.
