The CEC titanium seatpost offset 13 mm embodies the excellence of the Carbon Endurance Component brand, developed by Pierre-Arnaud Le Magnan (founder of Chiru Bikes) and backed by over 35 years of expertise in high-end components for ultra-endurance. Entirely made from titanium 3Al/2.5V, this seatpost combines exceptional lightness, natural vibration filtering and uncompromising strength. With its 13 mm setback, it offers ideal positioning for cyclists seeking comfort and performance on road, gravel or MTB.

Why choose titanium for your seatpost

Titanium is recognized as the "Holy Grail" of cycling materials for its unique ability to absorb vibrations while maintaining optimal structural rigidity. Unlike carbon or aluminum posts, a CEC titanium post naturally filters road imperfections without compromising power transfer, thus offering superior comfort over long distances. The brushed finish integrates harmoniously with Chiru titanium frames or any other premium build.

Full titanium construction: tube, cradle and hardware

• Titanium 3Al/2.5V tube: alloy offering the best compromise between vertical flexibility (comfort) and lateral rigidity (precision). Standard 27.2 mm diameter compatible with most road, gravel and MTB frames.
• Titanium cradle and hardware: unlike entry-level models using aluminum and steel, the 13Ti range features a titanium head and titanium hardware for total mechanical consistency and exceptional durability.
• Two-bolt clamping system: precise adjustment of saddle angle and fore-aft position, compatible with 7 mm round rails (metal) and 7x10 mm oval rails (carbon).

Available variants

The CEC 13 Ti seatpost is offered in three lengths to suit all body types and frame configurations:

• 280 mm variant (#280-13Ti): S length, weight 180 g — ideal for small frames or cyclists seeking minimum insertion.
• 330 mm variant (#330-13Ti): M length, weight 210 g — versatile size for most cyclists and road/gravel configurations.
• 380 mm variant (#380-13Ti): L length, weight 230 g — recommended for large frame sizes, MTBs or configurations requiring significant extension.

Competition-proven performance

CEC seatposts equip Chiru Bikes frames (Vagus, Allure, Kegeti, Highlander, Divider) and have been tested in the most extreme conditions by Team Chiru during ultra-distance events such as the Atlas Mountain Race, Roc d'Azur or Cyclingworld. The maximum user weight of 100 kg guarantees total reliability even on technical terrain.

Compatibility and installation

• Diameter: 27.2 mm (universal road/gravel/MTB standard)
• Recommended seat clamp: CEC #S32 titanium, outer diameter 31.8 mm (sold separately)
• Offset: 13 mm setback — ideal compromise between sporty position and balance on the bike
• Markings: laser-etched for durable readability of minimum insertion graduations

The CEC ecosystem: aesthetic and technical consistency

The 13Ti seatpost is part of the complete range of CEC titanium and carbon/Textreme components: titanium forks #375T and #400T, titanium handlebars #760T, T5X stems, #S32 seat clamps, thru-axles and titanium spacers. This comprehensive approach creates a homogeneous cockpit, both aesthetically (brushed finish) and technically (vibration damping, weight savings, corrosion resistance).
