Silca Hold Fast Carbon Paste

Secure your components with less torque and zero mess.

Trusted in pro-level builds and clean enough for everyday maintenance.

SILCA Hold Fast Carbon Paste delivers superior grip and cleaner installs through a high-tack silicone formula - setting it apart from traditional carbon grip pastes that rely on dyed greases and low-density texture additives.

Originally developed at the request of pro mechanics from VISMA | Lease a Bike, Hold Fast was engineered to solve real-world frustrations: stained clothing, slick grease bases, and poor grip at low torque. It increases surface friction, allowing for lower clamping torque while reducing the risk of fatigue, slippage, or damage to carbon and alloy parts. 

While most carbon pastes rely on grease as a base, Hold Fast uses a clean, high-tack silicone carrier that stays in place, wipes clean, and is safe on carbon, titanium, aluminum, and painted finishes.

Compared to industry standards from others, Hold Fast offers:

• Sticky, non-grease formula that resists sliding and migration
• Three to four times more silicate friction additive than typical carbon pastes
• Clear and dye-free—won’t stain fingers, clothing, or paint
• Designed to meet the torque and grip demands of modern performance bikes
• Ideal for cockpit and seatpost installs at lower torque values
• Easily cleans up with SILCA Gear Wipes

Recommended Application

• Carbon or alloy seatposts
• Dropper post assemblies
• Stem-to-steerer tube interfaces
• Handlebar clamps
• Saddle rails and clamps
• Any clamping interface where reduced torque and anti-slip performance is needed
