▬▬▬▬ Video Overview ▬▬▬▬
Carbon assembly paste should increase grip without creating mess, stains, or uncertainty. If you have ever wondered why handlebars slip or seat posts creep even at correct torque, this video explains exactly why.
In this launch video, Josh Poertner explains why most carbon pastes fall short and how SILCA Hold Fast Carbon Assembly Paste addresses real-world problems in cockpit and seat post interfaces for decades.
Developed in collaboration with pro mechanics from VISMA | Lease a Bike, Hold Fast replaces grease-based formulas with engineered “tackification” using a clear high-tack silicone carrier and refined friction modifiers. The result is secure clamping at lower torque, excellent resistance to movement and washout, and clean installs that stay clean.
Using microscope footage and real interface examples, Josh explains why grit shape, carrier chemistry, dielectric resistance, and long-term stability matter when carbon, aluminum, and titanium meet.
If you have dealt with slipping bars, creeping seat posts, stained shorts, or over-torqued components, this video shows how Hold Fast fixes each one.
