Product Information
Full details
Silca Hold Fast Carbon Paste is a high-performance assembly compound designed for professional mechanics and cycling enthusiasts who prioritize precision, cleanliness, and component longevity. By utilizing a high-tack silicone formula with three to four times the silicate friction additive of standard options, it ensures secure grip at lower clamping torques, protecting delicate carbon, titanium, and aluminum parts from damage. While its superior grip and non-staining, clear formula offer significant advantages over traditional dyed greases, users should be prepared for its high-tack consistency which requires careful, deliberate application during part alignment.

Extended Product Information
FAQs
Is this safe to use on titanium bolts?
Yes, it is designed for use on various surfaces including carbon, titanium, and aluminum.
Does this paste contain grease?
No, it uses a high-tack silicone formula which is free from the dyed greases found in traditional assembly pastes.
Can I use this on threaded interfaces?
This product is designed as a friction paste for high-grip interfaces; for threaded parts, use a dedicated anti-seize or thread locker.
How often should I re-apply?
It is recommended to clean and re-apply whenever you remove or adjust the specific component to maintain optimal friction.
Will this stain my white bike frame?
No, the formula is clear and dye-free, meaning it will not leave the dark, unsightly stains typical of standard carbon pastes.
Troubleshooting
Component feels too difficult to slide into place
Ensure you are using a thin, consistent layer. If the paste is too thick, wipe off the excess and re-seat the part.
Visible white residue after installation
Use a lint-free cloth or a dedicated bike cleaner to wipe away excess material from the outer surface of the junction.
Pros and Cons
Pros
- Significantly higher friction for reduced clamping force requirements
- Clear, non-staining formula protects frame paint and clothing
- Resists migration due to high-tack silicone base
- Safe for carbon, titanium, aluminum, and painted surfaces
Cons
- Higher viscosity may feel stickier than traditional greases
- Requires thorough cleaning before re-application to ensure efficacy
- Professional-grade volume may exceed needs for casual occasional use
Setup, Compatibility & Care
To ensure maximum effectiveness, start by thoroughly cleaning the contact surfaces with isopropyl alcohol to remove any existing grease or grime. Apply a thin, even layer of the Silca Hold Fast Carbon Paste to the component interface. When installing, align your parts carefully, as the high-tack nature of the paste makes micro-adjustments slightly more difficult than with standard, slippery grease. After assembly, wipe away any excess paste from the frame or component edges to prevent dirt buildup. The product is compatible with all standard bike frame materials, but always refer to your specific component manufacturer's torque recommendations.
