The CEC #370 carbon fork embodies technical excellence in the service of ultra-endurance cycling and long-distance road challenges. Designed by CEC (Carbon Endurance Components), this rigid carbon fork combines exceptional lightness (approximately 440 g), controlled stiffness and vibration absorption to maximize comfort and efficiency on the most demanding rides.

Technical summary and philosophy

The #370 fork is part of the CEC ecosystem designed for titanium and carbon endurance road bike frames. Its 370 mm axle-to-crown height and 45 mm rake offer balanced geometry, while the tapered steerer (1"1/8 - 1"1/2) ensures directional precision and compatibility with modern headsets. The internal routing for the brake hose ensures clean aesthetics and optimal protection. Designed for Flat Mount disc brakes (140/160 mm) and 12 mm thru-axle, this fork meets current standards for braking power and lateral stiffness.

Technical highlights

• High-performance T700 UD carbon: Monocoque construction in unidirectional carbon fibers offering excellent stiffness-to-weight ratio and natural filtering of road vibrations, crucial over long distances.
• Featherweight: Approximately 440 g including accessories, 100 to 250 g less than an equivalent aluminum fork — a significant gain in bike agility and responsiveness.
• Wide tire compatibility: Clearance up to 700 x 34c allowing comfortable tires (32-34 mm) to absorb road imperfections without loss of efficiency.
• Internal routing: Brake hose passage inside the steerer for clean installation, increased protection and better aerodynamics.
• ISO 4210-2:2015 standard: Compliance with international safety standards for road bikes, guaranteeing reliability and durability up to 100 kg user weight.

Geometry and standards

The 1"1/8 - 1"1/2 tapered steerer (290-300 mm length) integrates with 56/44 mm semi-integrated headsets, a widespread standard on modern road and gravel frames. The 45 mm rake and 370 mm axle-to-crown height are calibrated for endurance frames, offering stability on descents and liveliness when accelerating. The 12 x 100 mm thru-axle ensures maximum stiffness and perfect wheel centering, essential for disc brake precision.

Use and compatibility

This fork is designed to pair with titanium and carbon endurance road frames, notably the Chiru Kunlun models (original carbon #372 version) and other frames accepting a disc brake road fork. It excels on long-distance roads, road bikepacking, ultra-cycling and all rides where vertical compliance, lightness and reliability are paramount. The 40 mm crown diameter requires the use of a slotted crown race only.

Finish and delivery

Finish in matte clear coat highlighting the carbon weave and durably protecting the fibers. The fork is delivered with 12 x 100 mm thru-axle, steerer expander and aluminum cap — everything needed for immediate installation by a qualified mechanic.
