Hold Fast Carbon Paste

What Our Gearhead® Experts Are Saying:

"Hold Fast Carbon Paste changed how I think about cockpit installs entirely. I was running my stem bolts tighter than I should have been because I never fully trusted my old carbon paste to hold at the recommended torque spec, and switching to Hold Fast let me actually dial back to the manufacturer limit without second guessing the grip. The silicone base has zero migration after weeks of riding, it has not stained a single surface, and cleanup is genuinely effortless compared to anything grease based I have used before."

Carbon paste is one of those products that rarely gets attention until something goes wrong, and the Silca Hold Fast Carbon Paste was built specifically to make sure nothing does. Its origin sits in a practical frustration: the pro mechanics at VISMA Lease-a-Bike needed a paste that could deliver real grip at the low torque values demanded by modern carbon components, without the staining, migration, and inconsistent friction that characterize most grease based alternatives. What they developed with Silca is a product that holds up under the demands of professional racing and translates directly to anyone who cares about doing the job right.

The core difference is the carrier. Where virtually every other carbon paste on the market uses a grease base, Hold Fast uses a high-tack silicone that does not migrate, does not thin under pressure, and does not leave residue on surrounding surfaces. The silicate friction additive is loaded at three to four times the concentration of typical carbon pastes, which means the surface friction increase is real and measurable rather than marginal. The result is a paste that allows installers to meet manufacturer torque specifications with confidence, reducing the risk of fatigue cracking and hardware damage that comes from over-tightening to compensate for inadequate grip. The formula is completely clear and dye free, which eliminates the staining on fingers, gloves, clothing, and painted frame surfaces that makes most carbon paste installs feel like a damage control exercise.

Compatibility is broad across carbon, titanium, aluminum, and painted finishes, making Hold Fast the right choice for seatpost, stem, handlebar, and cleat installs across every category of performance bike. Cleanup requires nothing more than a SILCA Gear Wipe, leaving surfaces clean and ready for inspection. For mechanics and riders who hold their equipment to a high standard, this is the paste that matches that standard without compromise.
