The CEC #S32 Seatpost Collar embodies Taiwanese excellence in titanium bicycle components. Designed for demanding cyclists seeking the perfect balance between lightness, strength and durability, this pure titanium 3Al/2.5V collar weighs only 23 grams while offering uncompromising strength. Its 31.8 mm diameter makes it compatible with most high-end frames equipped with 27.2 mm seatposts, whether for road, gravel or MTB setups.

Aerospace titanium excellence

• Premium titanium alloy: Manufactured in 3Al/2.5V titanium alloy (or Grade 5 Ti6Al4V depending on version), the same material used in aerospace, offering exceptional strength-to-weight ratio and total corrosion resistance, even in extreme conditions (salt, humidity, mud).
• Featherweight 23 g: Every gram counts in competition or bikepacking — this collar halves the weight of standard aluminum collars without compromising reliability.
• Timeless aesthetics: Natural brushed titanium finish that enhances high-end titanium, steel or carbon frames, requiring no special maintenance.
• Integrated titanium hardware: Titanium clamping bolt for homogeneous assembly, avoiding any risk of galvanic corrosion and ensuring maximum longevity.

Performance and compatibility

• 31.8 mm diameter: Universal standard for frames with 31.8 mm external seat tube, compatible with 27.2 mm seatposts (road, gravel, modern MTB).
• Reliable and progressive clamping: Recommended torque of 5-6 Nm maximum, allowing firm seatpost retention without risk of tube crushing.
• Compact height 11-12 mm: Clean and discreet design that integrates perfectly with the frame line.
• Simple installation: Quick assembly with Allen key (4 or 5 mm hex depending on version), no specialized tools required.

Premium manufacturer reference

The CEC #S32 collar is the original component chosen by Chiru Bikes to equip their Veldt, Vagus, Divider, Allure and Highlander titanium frames — technical validation by one of the major players in French titanium gravel and MTB. CEC, a Taiwanese manufacturer recognized for its precision titanium components (seatposts, thru-axles, forks), delivers here a product that meets the strictest standards of the cycling industry.

Field applications

• Gravel and bikepacking: Absolute resistance to weather and prolonged vibrations, ideal for long-distance raids.
• Performance road: Valuable weight savings for climbing and time trials, without compromising stiffness.
• XC and All-Mountain MTB: Perfect hold even on rough terrain, compatibility with telescopic seatposts (droppers).
• Cyclocross and endurance road: Impeccable retention over time, even after thousands of kilometers and dozens of assemblies/disassemblies.

A lasting investment

Unlike anodized aluminum collars whose finish wears over time, titanium indefinitely retains its appearance and mechanical properties. The CEC #S32 is a component for life, which will go through several frame builds without weakening. Its initial cost is fully justified by its exceptional longevity and perfect integration on high-end builds.
