A fork designed for ultra distance

The CEC #400W was developed for cyclists who rack up the kilometers without compromise. Its T700 carbon architecture prioritizes fatigue resistance while maintaining a contained weight. The 400 mm axle-to-crown length and adjustable offset allow fine-tuning of geometry, whether you're seeking the stability of a loaded tourer or the liveliness of a fast gravel bike.

Compatibility and standards

This fork integrates perfectly on CHIRU VAGUS Adventure titanium frames, X-ROOT, and any modern gravel frame with tapered head tube. It accepts a crown diameter of 40 mm (split crown mandatory). The matte clear varnish finish highlights the exposed carbon fibers for a technical and premium appearance. Compliant with ISO 4210-2:2015 standard (tested according to ISO 4210-6:2015), it is approved for a maximum rider weight of 100 kg, luggage included (up to 3 kg per side on lateral mounts).

Accessories and installation

Delivered ready to install with its CEC 100×12 mm front axle, M5×10 titanium hardware, steerer expander and rubber caps for cable routing. The 290 mm steerer cuts easily to the desired length. Cyclists equipped with hub dynamos will appreciate the dedicated internal routing with top exit, compatible notably with CINQ PLUG5 USB chargers.
