SAC-2 Carbon and Alloy Assembly Compound helps create a tighter grip between two slippery surfaces. Highly recommended when installing the Supercross BLK Forks, and Supercross BLK Carbon Bars on the Supercross BMX ENVY BLK 2 BMX Racing Frame.
Perfect for the bond area between the Carbon Surfaces of Carbon Bars, Carbon Stems, Carbon Forks, Carbon Seatposts, anywhere you might have an area where the Carbon to alloy or Carbon to Carbon area might cause a bit of slippage.
