This 5-piece set of R&G Titanium Sprocket Nuts are made from grade 5 – 6AL-4V – 1068 MPA titanium? meaning they offer extraordinary strength and weight reduction. Our Black Titanium Sprocket Nuts go through a PVD (physical vapour deposition) treatment? ensuring longevity and corrosion resistance. ? Only use Manufacturer torque settings? 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? before using tools – this will help prevent accidental damage. ? Fit R&G Sprocket Nuts along with a medium thread lock? 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? 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? and protect with a corrosion inhibitor.*Please purchase the
