Juice Lubes Carbon Juice Carbon-Fibre Friction Assembly Paste - Review

Introduction

Carbon Juice is a friction-boosting assembly paste designed to increase grip between carbon components—or carbon and metal—on bicycles. Ideal for cyclists fitting carbon seatposts, handlebars, stems, or frame parts, it supports proper torque tightening without slippage—especially helpful for road, MTB, cyclocross, or commuter bikes.

Design & Build Quality

Packaged in a 50 ml pot, Carbon Juice features a clear, white beaded gel—viscous yet easy to spread, avoiding messy stained fingers. The gel is infused with pliable micro-beads that deform under clamp pressure, boosting both friction and surface conformity. The packaging is recyclable, supporting environmentally conscious consumers.

Performance & Features

Carbon Juice excels at preventing slipping of carbon-to-carbon or carbon-to-metal interfaces, enabling you to apply the manufacturer’s recommended torque without fear of over-tightening or damage. The bead-infused gel ensures consistent coverage and enhanced grip, while its easy “blob-and-wipe” application makes installation swift and mess-free. A small amount goes a long way—making the pot last for numerous component installations.

Pros, Cons & Verdict

Pros

• Superior grip for carbon-on-carbon or carbon-on-metal connections.
• Prevents over-tightening, protecting fragile carbon parts.
• User-friendly application—clear, easy-spread gel with minimal mess.

Verdict

Juice Lubes’s Carbon Juice Assembly Paste is a must-have for any cyclist using expensive carbon components. Its friction-boosting formula ensures secure clamping, proper torque, and damage prevention—all with clean, easy application. While stock may fluctuate and the container size is modest, the performance and lasting value make it a standout among carbon assembly products.
