This 5-piece set of R&G Titanium Sprocket Nuts are made from grade 5 - 6AL-4V - 1068 MPA titanium&-44; meaning they offer extraordinary strength and weight reduction. Our Black Titanium Sprocket Nuts go through a PVD -physical vapour deposition- treatment&-44; ensuring longevity and corrosion resistance. • Only use Manufacturer torque settings&-44; between 33 - 45nm.• Kits are offered as bike-specific fitments. If you have a variation of a standard model you may require an alternative kit. • Please check the thread fitment by hand&-44; before using tools - this will help prevent accidental damage. • Fit R&G Sprocket Nuts along with a medium thread lock&-44; after cleaning bolt threads of all corrosion and dirt. Titanium requires an anti-galling lubricant and must not be fitted dry -included-.• This is a critical safety component - it must be fitted by a competent mechanic. • To avoid marking the Sprocket Nuts&-44; use a 6-sided socket and stretch a rubber glove -or similar- over the socket before trying to tighten up. • Clean as part of your regular maintenance&-44; and protect with a corrosion inhibitor.*Please purchase the R&G Thread Lock 10ml when purchasing R&G Titanium Sprocket Nuts- """""""
