Our WEAPON Nuclear Carbon Fiber Aero track frameset is Press Release: Nuclear represents the pinnacle of design for track and fixed gear racing from WEAPON.
- Full Carbon Fiber T700 – using full carbon fiber T700 in bicycle framesets combines the advantages of lightweight, high strength, durability, and design versatility, making it an ideal material for high-performance track bicycles.
- Aerodynamic Design – Extraordinary Capability: When we developed the NUCLEAR, we weren’t satisfied with another open-mold race bike. After years of CFD modeling and design tweaks, the Ultro has been sculpted into slippery aerodynamic shapes, with a hidden seatpost clamp, and an aero seatpost, allowing you to unleash your fastest self.
- Stiffness & Control – The Power to Harness: Fitted with oversized tubing and a tapered steerer, the power delivery is precise and direct to the wheels. Railing through corners, the tubing ensures stiffness where you want it and comfort and support when you need it.
- Simple & Effective – Built-in Flexibility: Created for flexibility, the Nuclear can quickly adapt to you and holds to proven industry standards. With its English threaded bottom bracket and super smooth, you can easily swap parts to suit whatever you throw at the NUCLEAR.
- A re-tuned, fixed-gear crit-specific, track geometry – The new geometry features a higher bottom bracket, a shorter chainstay length, and an increased fork rake, further reducing toe overlap and providing a more stable ride quality; a response to ever-higher race speeds at events such as the Red Hook Criterium.
- Inner Cabling design – No matter if you’re racing on the track or riding through the city, the internal cable routing design of this frame will make you fall in love with it every time.
The ambition of the WEAPON Nuclear aero track frameset is to become one of the best carbon track frames in the world.
